Basis of Presentation and Description of Business [Abstract]
Basis of Presentation and Description of Business [Text Block]	Note 1 – Basis of Presentation and Description of Business Basis of Presentation As used in these Notes to Condensed Consolidated Financial Statements, the terms “Quaker,” “Quaker Houghton,” the “Company,” “we,” and “our” refer to Quaker Chemical Corporation (doing business as Quaker Houghton), its subsidiaries, and associated companies, unless the context otherwise requires. As used in these Notes to Condensed Consolidated Financial Statements, the term Legacy Quaker refers to the Company prior to the closing of its combination with Houghton International, Inc. (“Houghton”) (herein referred to as the “Combination”). The condensed consolidated financial statements included herein are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial reporting and the United States Securities and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the financial statements reflect all adjustments which are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”). Description of Business The Company was organized in 1918, incorporated as a Pennsylvania business corporation in 1930, and in August 2019 completed the Combination with Houghton to form Quaker Houghton. Quaker Houghton is the global leader in industrial process fluids. With a presence around the world, including operations in over 25 countries, the Company’s customers include thousands of the world’s most advanced and specialized steel, aluminum, automotive, aerospace, offshore, can, mining, and metalworking companies. Quaker Houghton develops, produces, and markets a broad range of formulated chemical specialty products and offe rs chemical management services (which the Company refers to as “Fluidcare”) for various heavy industrial and manufacturing applications throughout its four segments: Americas; Europe, Middle East and Africa (“EMEA”); Asia/Pacific; and Global Specialty Businesses. Hyper-inflationary economies Based on various indices or index compilations being used to monitor inflation in Argentina as well as economic instability, effective July 1, 2018, Argentina’s economy was considered hyper-inflationary under U.S. GAAP. As of, and for the three and six months ended June 30, 2021, the Company's Argentine subsidiaries represented less than 1 % of the Company’s consolidated total assets and net sales, respectively. During the three and six months ended June 30, 2021, the Company recorded $ 0.1 million and $ 0.3 million, respectively, of remeasurement losses associated with the applicable currency conversions related to Argentina. Comparatively, during the three and six months ended June 30, 2020, the Company recorded less than $ 0.1 million and $ 0.1 million, respectively, of remeasurement losses associated with the applicable currency conversions related to Argentina. These losses were recorded within foreign exchange losses, net, which is a component of other income (expense), net, in the Company’s Condensed Consolidated Statements of Operations. COVID-19 Management continues to monitor the impact that the COVID-19 pandemic is having on the Company, the overall specialty chemical industry, and the economies and markets in which the Company operates. The full extent of the COVID-19 pandemic related business and travel restrictions and changes to business and consumer behavior intended to reduce its spread are uncertain as of the date of this Quarterly Report on Form 10-Q for the period ended June 30, 2021 (the “Report”) as COVID-19 and the responses of governmental authorities continue to evolve globally. Further, management continues to evaluate how COVID-19-related circumstances, such as remote work arrangements, affect financial reporting processes, internal control over financial reporting, and disclosure controls and procedures. While the circumstances have presented and are expected to continue to present challenges, at this time, Management does not believe that COVID-19 has had a material impact on financial reporting processes, internal control over financial reporting, and disclosure controls and procedures. The Company cannot reasonably estimate the magnitude of the effects these conditions will have on the Company’s operations in the future as they are subject to significant uncertainties relating to the ultimate geographic spread of the virus, the incidence and severity of the symptoms, the duration or resurgences of the outbreak including the impact of new variants, the global availability and acceptance of vaccines as well as their efficacy, the length of the travel restrictions and business closures imposed by governments of impacted countries, and the economic response by governments of impacted countries, all of which continue to evolve. To the extent that the Company’s customers and suppliers continue to be significantly and adversely impacted by COVID-19, this could reduce the availability, or result in delays, of materials or supplies to or from the Company, which in turn could significantly interrupt the Company’s business operations. Such impacts could grow and become more significant to the Company’s operations and the Company’s liquidity or financial position. Therefore, given the speed and frequency of continuously evolving developments with respect to this pandemic, the Company cannot reasonably estimate the magnitude or the full extent to which COVID-19 may impact the Company’s results of operations, liquidity or financial position.

Business Acquisitions	Jun. 30, 2021
Business Acquisitions [Abstract]
Business acquisitions disclosure [Text Block]	Note 2 – Business Acquisitions 2021 Acquisitions In June 2021, the Company acquired certain assets for its chemical maskants product line in the Global Specialty Businesses reportable segment for 2.3 million EUR or approximately $ 2.8 million. The Company accounted for the acquisition using the asset acquisition method under ASC 805, Business Combinations . In February 2021, the Company acquired a tin-plating solutions business for the steel end market for approximately $ 25 million. This acquisition is part of each of the Company’s geographic reportable segments. The Company allocated $ 19.6 million of the purchase price to intangible assets, comprised of $ 18.3 million of customer relationships, to be amortized over 19 years ; $ 0.9 million of existing product technology to be amortized over 14 years ; and $ 0.4 million of a licensed trademark to be amortized over 3 years . In addition, the Company recorded $ 5.0 million of goodwill related to expected value not allocated to other acquired assets, all of which is expected to be tax deductible. As of June 30, 2021, the allocation of the purchase price has not been finalized and the one year measurement period has not ended. Further adjustments may be necessary as a result of the Company’s on-going assessment of additional information related to the fair value of assets acquired and liabilities assumed. Additionally, in February 2021, the Company acquired a 38 % ownership interest in a Germany-based, high-tech provider of coolant control and delivery systems for approximately 1.4 million EUR or approximately $ 1.7 million. The Company recorded this investment as an equity method investment within the Condensed Consolidated Financial Statements. The results of operations of the acquired assets and businesses subsequent to the respective acquisition dates are included in the Condensed Consolidated Statements of Operations as of June 30, 2021. Applicable transaction expenses associated with these acquisitions are included in Combination, integration and other acquisition-related expenses in the Company’s Condensed Consolidated Statements of Operations. Certain pro forma and other information is not presented, as the operations of the acquired assets and businesses are not considered material to the overall operations of the Company for the periods presented. Previous Acquisitions In December 2020, the Company completed its acquisition of Coral Chemical Company (“Coral”), a privately held, U.S.-based provider of metal finishing fluid solutions. The acquisition provides technical expertise and product solutions for pre-treatment, metalworking and wastewater treatment applications to the beverage cans and general industrial end markets. The original purchase price was approximately $ 54.1 million, subject to routine and customary post-closing adjustments related to working capital and net indebtedness levels. The Company anticipates finalizing its post-closing adjustments for the Coral acquisition during 2021 and currently estimates it will receive approximately $ 0.1 million to settle such adjustments. The following table presents the preliminary estimated fair values of Coral net assets acquired: Measurement December 22, December 22, Period 2020 2020 (1) Adjustments (as adjusted) Cash and cash equivalents $ 958 $ — $ 958 Accounts receivable 8,473 — 8,473 Inventories 4,527 — 4,527 Prepaid expenses and other assets 181 — 181 Property, plant and equipment 10,467 652 11,119 Intangible assets 30,300 (500) 29,800 Goodwill 2,814 270 3,084 Total assets purchased 57,720 422 58,142 Long-term debt including current portions and finance leases 183 556 739 Accounts payable, accrued expenses and other accrued liabilities 3,482 — 3,482 Total liabilities assumed 3,665 556 4,221 Total consideration paid for Coral 54,055 (134) 53,921 Less: estimated purchase price settlement — (134) (134) Less: cash acquired 958 — 958 Net cash paid for Coral $ 53,097 $ — $ 53,097 (1) As previously disclosed in the Company’s 2020 Form 10-K . Measurement period adjustments recorded during the first six months of 2021 include certain adjustments related to refining original estimates for assets and liabilities for certain acquired finance leases, as well the adjustment to reflect the expected settlement of post-closing working capital and net indebtedness true ups to the original purchase price. As of June 30, 2021, the allocation of the purchase price for Coral has not been finalized and the one year measurement period has not ended. Further adjustments may be necessary as a result of the Company’s on-going assessment of additional information related to the fair value of assets acquired and liabilities assumed. In May 2020, the Company acquired Tel Nordic ApS (“TEL”), a company that specializes in lubricants and engineering primarily in high pressure aluminum die casting for its Europe, Middle East and Africa (“EMEA”) reportable segment. Consideration paid was in the form of a convertible promissory note in the amount of 20.0 million DKK, or approximately $ 2.9 million, which was subsequently converted into shares of the Company’s common stock. An adjustment to the purchase price of approximately 0.4 million DKK, or less than $ 0.1 million, was made as a result of finalizing a post-closing settlement in the second quarter of 2020. The Company allocated approximately $ 2.4 million of the purchase price to intangible assets to be amortized over 17 years . In addition, the Company recorded approximately $ 0.5 million of goodwill, related to expected value not allocated to other acquired assets, none of which will be tax deductible. As of June 30, 2021, the allocation of the purchase price of TEL was finalized and the one year measurement period ended. In March 2020, the Company acquired the remaining 49 % ownership interest in one of its South African affiliates, Quaker Chemical South Africa Limited (“QSA”) for 16.7 million ZAR, or approximately $ 1.0 million, from its joint venture partner PQ Holdings South Africa. QSA is a part of the Company’s Europe, Middle East and Africa (“EMEA”) reportable segment. As this acquisition was a change in an existing controlling ownership, the Company recorded $ 0.7 million of excess purchase price over the carrying value of the noncontrolling interest in Capital in excess of par value. In October 2019, the Company completed its acquisition of the operating divisions of Norman Hay plc (“Norman Hay”), a private U.K. company that provides specialty chemicals, operating equipment, and services to industrial end markets. The original purchase price was 80.0 million GBP, on a cash-free and debt-free basis, subject to routine and customary post-closing adjustments related to working capital and net indebtedness levels. The Company finalized its post-closing adjustments for the Norman Hay acquisition and paid approximately 2.5 million GBP during the first quarter of 2020 to settle such adjustments.

Recently Issued Accounting Standards	Jun. 30, 2021
New Accounting Pronouncements And Changes In Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles [Text Block]	Note 3 – Recently Issued Accounting Standards Recently Issued Accounting Standards Adopted The Financial Accounting Standards Board (“FASB”) issued Account Standards Update (“ASU”) ASU 2019-12 , Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes in December 2019 to simplify the accounting for income taxes. The guidance within this accounting standard update removes certain exceptions, including the exception to the incremental approach for certain intra-period tax allocations, to the requirement to recognize or not recognize certain deferred tax liabilities for equity method investments and foreign subsidiaries, and to the general methodology for calculating income taxes in an interim period when a year-to- date loss exceeds the anticipated loss for the year. Further, the guidance simplifies the accounting related to franchise taxes, the step up in tax basis for goodwill, current and deferred tax expense, and codification improvements for income taxes related to employee stock ownership plans. The guidance is effective for annual and interim periods beginning after December 15, 2020. The Company adopted this standard on a prospective basis, effective January 1, 2021. There was no cumulative effect of adoption recorded within retained earnings on January 1, 2021. The FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting in March 2020. The FASB subsequently issued ASU 2021-01, Reference Rate Reform (Topic 848): Scope in January 2021 which clarified the guidance but did not materially change the guidance or its applicability to the Company. The amendments provide temporary optional expedients and exceptions for applying U.S. GAAP to contract modifications, hedging relationships and other transactions to ease the potential accounting and financial reporting burden associated with transitioning away from reference rates that are expected to be discontinued, including the London Interbank Offered Rate (“LI BOR”). ASU 2020-04 is effective for the Company as of March 12, 2020 and generally can be applied through December 31, 2022. As of June 30, 2021, the expedients provided in ASU 2020-04 do not presently impact the Company; however, the Company will continue to monitor for potential impacts on its consolidated financial statements.

Net Sales and Revenue Recognition	6 Months Ended
Net Sales and Revenue Recognition	Jun. 30, 2021
Revenue From Contract With Customer [Abstract]
Revenue From Contract With Customer [TextBlock]	Note 5 – Net Sales and Revenue Recognition Business Description The Company develops, produces, and markets a broad range of formulated chemical specialty products and offers chemical management services (“Fluidcare”) for various heavy industrial and manufacturing applications throughout its four segments. A significant portion of the Company’s revenues are realized from the sale of process fluids and services made directly to manufacturers through its own employees and its Fluidcare programs, with the balance being handled through distributors and agents. As part of the Company’s Fluidcare business, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, revenue is recognized on a net reporting basis at the amount of the administrative fee earned by the Company for ordering the goods. The Company transferred third-party products under arrangements recognized on a net reporting basis of $ 16.7 million and $ 34.5 million for the three and six months ended June 30, 2021, respectively, and $ 6.2 million and $ 18.7 million for the three and six months ended June 30, 2020, respectively. As previously disclosed in the Company’s 2020 Form 10-K, during 2020, the Company’s five largest customers (each composed of multiple subsidiaries or divisions with semiautonomous purchasing authority) accounted for approximately 10 % of consolidated net sales, with its largest customer accounting for approximately 3 % of consolidated net sales. Revenue Recognition Model The Company applies the five-step model in the FASB’s guidance, which requires the Company to: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. Refer to the Company’s 2020 Form 10-K for additional information on the Company’s revenue recognition policies, including its practical expedients and accounting policy elections. Allowance for Doubtful Accounts As previously disclosed in the Company’s 2020 Form 10-K, during 2020, the Company adopted, as required, an accounting standard update related to the accounting and disclosure of credit losses effective January 1, 2020. The Company recognizes an allowance for credit losses, which represents the portion of its trade accounts receivable that the Company does not expect to collect over the contractual life, considering past events and reasonable and supportable forecasts of future economic conditions. The Company’s allowance for credit losses on its trade accounts receivables is based on specific collectability facts and circumstances for each outstanding receivable and customer, the aging of outstanding receivables, and the associated collection risk the Company estimates for certain past due aging categories, and also, the general risk to all outstanding accounts receivable based on historical amounts determined to be uncollectible. The Company does not have any off-balance-sheet credit exposure related to its customers. Contract Assets and Liabilities The Company recognizes a contract asset or receivable on its Condensed Consolidated Balance Sheet when the Company performs a service or transfers a good in advance of receiving consideration. A receivable is the Company’s right to consideration that is unconditional and only the passage of time is required before payment of that consideration is due. A contract asset is the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer. The Company had no material contract assets recorded on its Condensed Consolidated Balance Sheets as of June 30, 2021 or December 31, 2020. A contract liability is recognized when the Company receives consideration, or if it has the unconditional right to receive consideration, in advance of performance. A contract liability is the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration, or a specified amount of consideration is due, from the customer. The Company’s contract liabilities primarily represent deferred revenue recorded for customer payments received by the Company prior to the Company satisfying the associated performance obligation. Deferred revenues are presented within other current liabilities in the Company’s Condensed Consolidated Balance Sheets. The Company had approximately $ 4.3 million and $ 4.0 million of deferred revenue as of June 30, 2021 and December 31, 2020, respectively. For the six months ended June 30, 2021, the Company satisfied all of the associated performance obligations and recognized into revenue the advance payments received and recorded as of December 31, 2020. Disaggregated Revenue The following tables disaggregate the Company’s net sales by segment, geographic region, customer industry, and timing of revenue recognized for the three and six months ended June 30, 2021 and 2020.

Leases	6 Months Ended
Leases	Jun. 30, 2021
Leases [Abstract]
Leases Disclosure [TextBlock]	Note 6 – Leases The Company determines if an arrangement is a lease at its inception. This determination generally depends on whether the arrangement conveys the right to control the use of an identified fixed asset explicitly or implicitly for a period of time in exchange for consideration. Control of an underlying asset is conveyed if the Company obtains the rights to direct the use of, and obtains substantially all of the economic benefits from the use of, the underlying asset. Lease expense for variable leases and short-term leases is recognized when the obligation is incurred. The Company has operating leases for certain facilities, vehicles and machinery and equipment with remaining lease terms up to 10 years . In addition, the Company has certain land use leases with remaining lease terms up to 94 years . The lease term for all of the Company’s leases includes the non-cancellable period of the lease plus any additional periods covered by an option to extend the lease that the Company is reasonably certain it will exercise. Operating leases are included in right of use lease assets , other current liabilities and long-term lease liabilities on the Condensed Consolidated Balance Sheet. Right of use lease assets and liabilities are recognized at each lease’s commencement date based on the present value of its lease payments over its respective lease term. The Company uses the stated borrowing rate for a lease when readily determinable. When a stated borrowing rate is not available in a lease agreement, the Company uses its incremental borrowing rate based on information available at the lease’s commencement date to determine the present value of its lease payments. In determining the incremental borrowing rate used to present value each of its leases, the Company considers certain information including fully secured borrowing rates readily available to the Company and its subsidiaries. The Company has immaterial finance leases, which are included in property, plant and equipment, current portion of long-term debt and long-term debt on the Condensed Consolidated Balance Sheet. Operating lease expense is recognized on a straight-line basis over the lease term. Operating lease expense for the three and six months ended June 30, 2021 was $ 3.6 million and $ 7.2 million, respectively. Comparatively, operating lease expense for the three and six months ended June 30, 2020 was $ 3.5 million and $ 6.9 million, respectively. Short-term lease expense for the three and six months ended June 30, 2021 was $ 0.2 million and $ 0.5 million, respectively. Comparatively, short-term lease expense for the three and six months ended June 30, 2020 was $ 0.4 million and $ 0.9 million, respectively. The Company has no material variable lease costs or sublease income for the three or six months ended June 30, 2021 and 2020. Cash paid for operating leases during the six months ended June 30, 2021 and 2020 was $ 7.1 million and $ 6.8 million, respectively. The Company recorded new right of use lease assets and associated lease liabilities of $ 3.9 million during the six months ended June 30, 2021. Supplemental balance sheet information related to the Company’s leases is as follows: June 30, December 31, 2021 2020 Right of use lease assets $ 36,160 $ 38,507 Other current liabilities 10,064 10,901 Long-term lease liabilities 25,668 27,070 Total operating lease liabilities $ 35,732 $ 37,971 Weighted average remaining lease term (years) 5.8 6.0 Weighted average discount rate 4.26% 4.20% Maturities of operating lease liabilities as of June 30, 2021 were as follows: June 30, 2021 For the remainder of 2021 $ 6,052 For the year ended December 31, 2022 9,400 For the year ended December 31, 2023 7,234 For the year ended December 31, 2024 5,355 For the year ended December 31, 2025 4,260 For the year ended December 31, 2026 and beyond 8,152 Total lease payments 40,453 Less: imputed interest (4,721) Present value of lease liabilities $ 35,732

Restructuring and Related Activities	6 Months Ended
Restructuring and Related Activities	Jun. 30, 2021
Restructuring And Related Activities [Abstract]
Restructuring And Related Activities Disclosure [Text Block]	Note 7 – Restructuring and Related Activities The Company’s management approved a global restructuring plan (the “QH Program”) as part of its plan to realize certain cost synergies associated with the Combination in the third quarter of 2019. The QH Program includes restructuring and associated severance costs to reduce total headcount by approximately 400 people globally, as well as plans for the closure of certain manufacturing and non-manufacturing facilities. The exact timing and total costs associated with the QH Program will depend on a number of factors and is subject to change; however, the Company currently expects reduction in headcount and site closures to continue to occur throughout 2021 and into 2022 under the QH Program and estimates that anticipated cost synergies realized from the QH Program will approximate one-times the restructuring costs incurred. Employee separation benefits will vary depending on local regulations within certain foreign countries and will include severance and other benefits. All costs incurred to date relate to severance costs to reduce headcount as well as costs to close certain facilities and are recorded in Restructuring and related charges in the Company’s Condensed Statements of Operations. As described in Note 4 of Notes to Condensed Consolidated Financial Statements, restructuring and related charges are not included in the Company’s calculation of reportable segments’ measure of operating earnings and therefore these costs are not reviewed by or recorded to reportable segments. Activity in the Company’s accrual for restructuring under the QH Program for the six months ended June 30, 2021 is as follows: QH Program Accrued restructuring as of December 31, 2020 $ 8,248 Restructuring and related charges 1,473 Cash payments (4,214) Currency translation adjustments (229) Accrued restructuring as of June 30, 2021 $ 5,278

Share-Based Compensation	6 Months Ended
Share-Based Compensation	Jun. 30, 2021
Disclosure of Compensation Related Costs, Share-based Payments [Abstract]
Disclosure of Compensation Related Costs, Share-based Payments [Text Block]	Note 8 – Share-Based Compensation The Company recognized the following share-based compensation expense in its Condensed Consolidated Statements of Operations for the three and six months ended June 30, 2021 and 2020: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Stock options $ 332 $ 353 $ 640 $ 785 Non-vested stock awards and restricted stock units 1,290 1,259 2,686 2,523 Non-elective and elective 401(k) matching contribution in stock — 1,162 1,553 1,162 Director stock ownership plan 216 54 419 94 Performance stock units 517 280 836 280 Annual incentive plan — (117) — 2,829 Total share-based compensation expense $ 2,355 $ 2,991 $ 6,134 $ 7,673 Share-based compensation expense is recorded in SG&A, except for $ 0.2 million and $ 0.5 million for the three and six months ended June 30, 2021, respectively, and $ 0.3 million and $ 0.8 million for the three and six months ended June 30, 2020, respectively, recorded within Combination, integration and other acquisition-related expenses. Stock Options During the first six months of 2021, the Company granted stock options under its long-term incentive plan (“LTIP”) that are subject only to time-based vesting over a three year period. For the purposes of determining the fair value of stock option awards, the Company used a Black-Scholes option pricing model and which primarily used the assumptions set forth in the table below: Number of options granted 25,250 Dividend yield 0.85 % Expected volatility 37.33 % Risk-free interest rate 0.60 % Expected term (years) 4.0 The fair value of these options is amortized on a straight -line basis over the vesting period. As of June 30, 2021, unrecognized compensation expense related to all stock options granted was $ 2.4 million, to be recognized over a weighted average remaining period of 2.3 years. Restricted Stock Awards and Restricted Stock Units During the six months ended June 30, 2021, the Company granted 17,692 non-vested restricted shares and 2,791 non-vested restricted stock units under its LTIP, which are subject to time-based vesting, generally over a three year period. The fair value of these grants is based on the trading price of the Company’s common stock on the date of grant. The Company adjusts the grant date fair value of these awards for expected forfeitures based on historical experience. As of June 30, 2021, unrecognized compensation expense related to the non-vested restricted shares was $ 6.3 million, to be recognized over a weighted average remaining period of 1.9 years, and unrecognized compensation expense related to non-vested restricted stock units was $ 1.1 million, to be recognized over a weighted average remaining period of 2.1 years. Performance Stock Units During the first six months of 2021, the Company granted performance-dependent stock awards (“PSUs”) as a component of its LTIP, which will be settled in a certain number of shares subject to market -based and time-based vesting conditions. The number of fully vested shares that may ultimately be issued as settlement for each award may range from 0 % up to 200 % of the target award, subject to the achievement of the Company’s total shareholder return (“TSR”) relative to the performance of the Company’s peer group, the S&P Midcap 400 Materials group. The service period required for the PSUs is three years and the TSR measurement period for the PSUs is from January 1 of the year of grant through December 31 of the year prior to issuance of the shares upon settlement. Compensation expense for PSUs is measured based on their grant date fair value and is recognized on a straight-line basis over the three year vesting period. The grant-date fair value of the PSUs granted during the first six months of 2021 was estimated using a Monte Carlo simulation on the grant date and using the following assumptions: (i) a risk-free rate of 0.29 %; (ii) an expected term of 3.0 years; and (iii) a three year daily historical volatility for each of the companies in the peer group, including Quaker Houghton. As of June 30, 2021, the Company estimates that it will issue approximately 14,698 fully vested shares as of the applicable settlement date of all outstanding PSUs awards based on the conditions of the PSUs and performance to date for each award. As of June 30, 2021, there was approximately $ 4.2 million of total unrecognized compensation cost related to PSUs, which the Company expects to recognize over a weighted-average period of 2.3 years. Annual Incentive Plan The Company maintains an Annual Incentive Plan (“AIP”), which may be settled in cash or a certain number of shares subject to performance-based and time-based vesting conditions. As of June 30, 2020, it was the Company’s intention to settle the 2020 AIP in shares, and therefore, expense associated with the AIP in 2020 was recorded as a component of share-based compensation expense. In the fourth quarter of 2020, the Company determined that it would settle the 2020 AIP in cash. Therefore, the share-based compensation associated with the AIP during the year ended December 31, 2020 was reclassified from a component of share-based compensation expense to incentive compensation. This determination and conclusion had no impact on the classification of AIP expense within the Company’s Condensed Consolidated Statement of Operations for the periods as both are a component of SG&A. As of June 30, 2021, it is the Company’s intention to settle the 2021 AIP in cash. Defined Contribution Plan The Company has a 401(k) plan with an employer match covering a majority of its U.S. employees. The Company matches 50 % of the first 6 % of compensation that is contributed to the plan, with a maximum matching contribution of 3 % of compensation. Additionally, the plan provides for non-elective nondiscretionary contributions on behalf of participants who have completed one year of service equal to 3 % of the eligible participants’ compensation. Beginning in April 2020 and continuing through March 2021, the Company matched both non-elective and elective 401(k) contributions in fully vested shares of the Company’s common stock rather than cash. For the three months ended June 30, 2021, there were no matching contributions in stock. For the six months ended June 30, 2021, total contributions were $ 1.5 million and for both the three and six months ended June 30, 2020, total contributions were $ 1.2 million.

Pension and Other Postretirement Benefits [Abstract]
Pension And Other Postretirement Benefits Disclosure [Text Block]	Note 9 – Pension and Other Postretirement Benefits The components of net periodic benefit cost for the three and six months ended June 30, 2021 and 2020 are as follows: Three Months Ended June 30, Six Months Ended June 30, Other Other Postretirement Postretirement Pension Benefits Benefits Pension Benefits Benefits 2021 2020 2021 2020 2021 2020 2021 2020 Service cost $ 316 $ 1,164 $ 2 $ 1 $ 632 $ 2,338 $ 3 $ 3 Interest cost 1,094 1,486 10 26 2,184 3,255 21 52 Expected return on plan assets (2,093) (1,761) — — (4,175) (3,720) — — Settlement charge — — — — — 22,667 — — Actuarial loss amortization 857 615 — 16 1,712 1,662 — 31 Prior service cost amortization 3 (41) — — 5 (81) — — Net periodic benefit cost $ 177 $ 1,463 $ 12 $ 43 $ 358 $ 26,121 $ 24 $ 86 As disclosed in the Company’s 2020 Form 10-K, in the fourth quarter of 2018, the Company began the process of terminating its legacy Quaker non-contributory U.S. pension plan (“Legacy Quaker U.S. Pension Plan”). During the third quarter of 2019, the Company received a favorable termination determination letter from the Internal Revenue Service (“I.R.S.”) and completed the Legacy Quaker U.S. Pension Plan termination during the first quarter of 2020. In order to terminate the Legacy Quaker U.S. Pension Plan in accordance with I.R.S. and Pension Benefit Guaranty Corporation requirements, the Company was required to fully fund the Legacy Quaker U.S. Pension Plan on a termination basis and the amount necessary to do so was approximately $ 1.8 million, subject to final true up adjustments, which were completed in the third quarter of 2020. In addition, the Company recorded a non-cash pension settlement charge at plan termination of approximately $ 22.7 million. This settlement charge included the immediate recognition into expense of the related unrecognized losses within accumulated other comprehensive (loss) income (“AOCI”) on the balance sheet as of the plan termination date. Employer Contributions As of June 30, 2021, $ 2.1 million and $ 0.1 million of contributions have been made to the Company’s U.S. and foreign pension plans and its other postretirement benefit plans, respectively . Taking into consideration current minimum cash contribution requirements, the Company currently expects to make full year cash contributions of approximately $ 6 million to its U.S. and foreign pension plans and less than $ 1 million to its other postretirement benefit plans in 2021

Income Taxes and Uncertain Income Tax Positions	Jun. 30, 2021
Taxes on Income and Uncertain Tax Positions [Abstract]
Taxes on Income [Text Block]	Note 11 – Income Taxes and Uncertain Income Tax Positions The Company’s effective tax rates for the three and six months ended June 30, 2021 were an expense of 32.2 % and 28.4 %, respectively, compared to an expense of 57.9 % and a benefit of 20.7 % for the three and six months ended June 30, 2020, respectively. The Company’s current year effective tax rates were largely impacted by the sale of certain held-for-sale real property assets related to the Combination, changes in foreign tax credit valuation allowances, tax law changes in a foreign jurisdiction and the income tax impacts of certain non-income tax credits recorded by the Company’s Brazilian subsidiaries described in Note 19 of Notes to Condensed Consolidated Financial Statements. Comparatively, the prior year effective tax rates were impacted by the tax effect of certain one-time pre-tax losses as well as certain tax charges and benefits in the prior year period including those related to changes in foreign tax credit valuation allowances, tax law changes in a foreign jurisdiction, changes in uncertain tax positions and the tax impacts of the Company’s termination of its Legacy Quaker U.S. Pension Plan. As of December 31, 2020, the Company had a deferred tax liability of $ 5.9 million, which primarily represents the Company’s estimate of non-U.S. taxes it will incur to repatriate certain foreign earnings to the U.S. The balance as of June 30, 2021 was $ 6.5 million. As of June 30, 2021, the Company’s cumulative liability for gross unrecognized tax benefits was $ 24.0 million, an increase of $ 1.8 million from the cumulative liability accrued as of December 31, 2020. The Company continues to recognize interest and penalties associated with uncertain tax positions as a component of taxes on income (loss) before equity in net income of associated companies in its Condensed Consolidated Statements of Operations. The Company recognized an expense for interest of approximately $ 0.2 million and $ 0.2 million and a benefit of less than $ 0.1 million and $ 0.2 million for penalties in its Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2021, respectively, and recognized an expense of $ 0.6 million and $ 0.6 million for interest and an expense of $ 0.6 million and $ 0.5 million for penalties in its Condensed Consolidated Statement of Operations for the three and six months ended June 30, 2020 , respectively. As of June 30, 2021, the Company had accrued $ 3.2 million for cumulative interest and $ 3.6 million for cumulative penalties in its Condensed Consolidated Balance Sheets, compared to $ 3.0 million for cumulative interest and $ 3.9 million for cumulative penalties accrued at December 31, 2020. During the six months ended June 30, 2021 and 2020, the Company recognized decreases of $ 0.8 million and $ 1.5 million, respectively, in its cumulative liability for gross unrecognized tax benefits due to the expiration of the applicable statutes of limitations for certain tax years. The Company estimates that during the year ending December 31, 2021 it will reduce its cumulative liability for gross unrecognized tax benefits by approximately $ 1.5 million due to the expiration of the statute of limitations with regard to certain tax positions. This estimated reduction in the cumulative liability for unrecognized tax benefits does not consider any increase in liability for unrecognized tax benefits with regard to existing tax positions or any increase in cumulative liability for unrecognized tax benefits with regard to new tax positions for the year ending December 31, 2021. The Company and its subsidiaries are subject to U.S. Federal income tax, as well as the income tax of various state and foreign tax jurisdictions. Tax years that remain subject to examination by major tax jurisdictions include Italy from 2006 , Brazil from 2011 , the Netherlands and China from 2015 , Mexico, Spain, Germany and the United Kingdom from 2016 , Canada and the U.S. from 2017 , India from fiscal year beginning April 1, 2018 and ending March 31, 2019 , and various U.S. state tax jurisdictions from 2011 . As previously reported, the Italian tax authorities have assessed additional tax due from the Company’s subsidiary, Quaker Italia S.r.l., relating to the tax years 2007 through 2015. The Company has filed for competent authority relief from these assessments under the Mutual Agreement Procedures (“MAP”) of the Organization for Economic Co-Operation and Development for all years except 2007. In 2020, the respective tax authorities in Italy, Spain and the Netherlands reached agreement with respect to the MAP proceedings which the Company has accepted. As of June 30, 2021, the Company has received $ 1.6 million in refunds from the Netherlands and Spain and expects to pay $ 2.6 million due to Italy in the second half of 2021. As of June 30, 2021, the Company believes it has adequate reserves for the remaining uncertain tax positions related to 2007. Houghton Italia, S.r.l is also involved in a corporate income tax audit with the Italian tax authorities covering tax years 2014 through 2018 . As of June 30, 2021, the Company has a $ 5.6 million reserve for uncertain tax positions relating to matters related to this audit. Since the reserve relates to the tax periods prior to August 1, 2019, the tax liability was established through purchase accounting related to the Combination. The Company has also submitted an indemnification claim against funds held in escrow by Houghton’s former owners and as a result, a corresponding $ 5.6 million indemnification receivable has also been established through purchase accounting. Houghton Deutschland GmbH is also under audit by the German tax authorities for the tax years 2015 through 2017 . Based on preliminary audit findings, primarily related to transfer pricing, the Company has recorded reserves for $ 0.9 million as of June 30, 2021. Of this amount, $ 0.8 million relates to tax periods prior to the Combination and therefore the Company has submitted an indemnification claim with Houghton’s former owners for any tax liabilities arising pre-Combination. As a result, a corresponding $ 0.8 million indemnification receivable has also been established to offset the $ 0.8 million tax liability.

Cash And Cash Equivalents Disclosure [Text Block]	Note 13 – Restricted Cash Prior to December 2020, the Company had restricted cash recorded in other assets related to proceeds from an inactive subsidiary of the Company which previously executed separate settlement and release agreements with two of its insurance carriers for an original total value of $35.0 million. The proceeds of both settlements were restricted and could only be used to pay claims and costs of defense associated with the subsidiary’s asbestos litigation. The proceeds of the settlement and release agreements were deposited into interest bearing accounts that earned less than $ 0.1 million offset by $ 0.5 million of net payments during the six months ended June 30, 2020. Due to the restricted nature of the proceeds, a corresponding deferred credit was established in other non-current liabilities for an equal and offsetting amount that continued until the restrictions lapsed. As disclosed in the Company’s 2020 Form 10-K, during December 2020, the restrictions ended on these previously received insurance settlements and the Company transferred the cash into an operating account. The following table provides a reconciliation of cash, cash equivalents and restricted cash as of June 30, 2021 and 2020 , as well as December 31, 2020 and 2019: June 30, December 31, 2021 2020 2020 2019 Cash and cash equivalents $ 145,610 $ 322,497 $ 181,833 $ 123,524 Restricted cash included in other current assets — 85 62 353 Restricted cash included in other assets — 19,173 — 19,678 Cash, cash equivalents and restricted cash $ 145,610 $ 341,755 $ 181,895 $ 143,555

The Company recorded $ 15.0 million and $ 29.8 million of amortization expense for the three and six months ended June 30, 2021, respectively. Comparatively, the Company recorded $ 13.7 million and $ 27.7 million of amortization expense for the three and six months ended June 30, 2020, respectively. Estimated annual aggregate amortization expense for the current year and subsequent five years is as follows: For the year ended December 31, 2021 $ 59,214 For the year ended December 31, 2022 59,564 For the year ended December 31, 2023 59,394 For the year ended December 31, 2024 58,750 For the year ended December 31, 2025 58,037 For the year ended December 31, 2026 57,740 The Company has four indefinite-lived intangible assets totaling $ 205.1 million as of both June 30, 2021 and December 31, 2020, including $ 204.0 million of indefinite-lived intangible assets for trademarks and tradename associated with the Combination. Goodwill and intangible assets that have indefinite lives are not amortized and are required to be assessed at least annually for impairment. The Company completes its annual goodwill and indefinite-lived intangible asset impairment test during the fourth quarter of each year. The Company continuously evaluates if triggering events indicate a possible impairment in one or more of its reporting units or indefinite-lived or long-lived assets. The Company previously disclosed in its 2020 Form 10-K that as of March 31, 2020, the Company concluded that the impact of COVID-19 did not represent a triggering event with regards to the Company’s reporting units or indefinite-lived and long-lived assets, except for the Company’s Houghton and Fluidcare trademarks and tradename indefinite -lived intangible assets. The determination of estimated fair value of the Houghton and Fluidcare trademarks and tradename indefinite-lived assets was based on a relief from royalty valuation method, which requires management’s judgment and often involves the use of significant estimates and assumptions, including assumptions with respect to the weighted average cost of capital (“WACC”) and royalty rates, as well as revenue growth rates and terminal growth rates. In the first quarter of 2020, as a result of the impact of COVID-19 driving a decrease in projected legacy Houghton net sales during that year and the impact of the sales decline on projected future legacy Houghton net sales as well as an increase in the WACC assumption utilized in the quantitative impairment assessment, the Company concluded that the estimated fair values of the Houghton and Fluidcare trademarks and tradename intangible assets were less than their carrying values. As a result, an impairment charge of $ 38.0 million was recorded in the first quarter of 2020 to write down the carrying values of these intangible assets to their estimated fair values. As of June 30, 2021, the Company continued to evaluate all potential triggering events, including the on-going impact of COVID- 19 on the Company’s operations, and the volatility and uncertainty in the economic outlook as a result of COVID-19, to determine if this indicated it was more likely than not that the carrying value of any of the Company’s reporting units or indefinite-lived or long- lived intangible assets were not recoverable. The Company concluded that the impact of COVID-19 did not represent a triggering event as of June 30, 2021. While the Company concluded that the impact of COVID-19 did not represent a triggering event as of June 30, 2021, the Company will continue to evaluate the impact of COVID-19 on the Company’s current and projected results. If the current economic conditions worsen or projections of the timeline for recovery are significantly extended, then the Company may conclude in the future that the impact from COVID-19 requires the need to perform further interim quantitative impairment tests, which could result in additional impairment charges in the future.

Debt [Text Block]	Note 15 – Debt Debt as of June 30, 2021 and December 31, 2020 includes the following: As of June 30, 2021 As of December 31, 2020 Interest Outstanding Interest Outstanding Rate Balance Rate Balance Credit Facilities: Revolver 1.59% $ 189,503 1.65% $ 160,000 U.S. Term Loan 1.59% 555,000 1.65% 570,000 EURO Term Loan 1.50% 148,115 1.50% 157,062 Industrial development bonds 5.26% 10,000 5.26% 10,000 Bank lines of credit and other debt obligations Various 2,165 Various 2,072 Total debt $ 904,783 $ 899,134 Less: debt issuance costs (9,550) (11,099) Less: short-term and current portion of long-term debts (48,079) (38,967) Total long -term debt $ 847,154 $ 849,068 Credit facilities The Company’s primary credit facility (as amended, the “Credit Facility”) is comprised of a $ 400.0 million multicurrency revolver (the “Revolver”), a $ 600.0 million term loan (the “U.S. Term Loan”), each with the Company as borrower, and a $ 150.0 million (as of August 1, 2019) Euro equivalent term loan (the “EURO Term Loan” and together with the “U.S. Term Loan”, the “Term Loans”) with Quaker Chemical B.V., a Dutch subsidiary of the Company as borrower, each with a five year term maturing in August 2024. Subject to the consent of the administrative agent and certain other conditions, the Company may designate additional borrowers. The maximum amount available under the Credit Facility can be increased by up to $ 300.0 million at the Company’s request if there are lenders who agree to accept additional commitments and the Company has satisfied certain other conditions. Borrowings under the Credit Facility bear interest at a base rate or LIBOR plus an applicable margin based upon the Company’s consolidated net leverage ratio. There are LIBOR replacement provisions that contemplate a further amendment if and when LIBOR ceases to be reported. The variable interest rate incurred on the outstanding borrowings under the Credit Facility as of and during the six months ended June 30, 2021 was approximately 1.6 %. In addition to paying interest on outstanding principal under the Credit Facility, the Company is required to pay a commitment fee ranging from 0.2 % to 0.3 % depending on the Company’s consolidated net leverage ratio to the lenders under the Revolver in respect of the unutilized commitments thereunder. The Company has unused capacity under the Revolver of approximately $ 206 million, net of bank letters of credit of approximately $ 4 million, as of June 30, 2021. The Credit Facility is subject to certain financial and other covenants. The Company’s initial consolidated net debt to consolidated adjusted EBITDA ratio could not exceed 4.25 to 1, with step downs in the permitted ratio over the term of the Credit Facility. As of June 30, 2021, the consolidated net debt to adjusted EBITDA may not exceed 4.00 to 1. The Company’s consolidated adjusted EBITDA to interest expense ratio cannot be less than 3.0 to 1 over the term of the agreement. The Credit Facility also prohibits the payment of cash dividends if the Company is in default or if the amount of the dividend paid annually exceeds the greater of $ 50.0 million and 20 % of consolidated adjusted EBITDA unless the ratio of consolidated net debt to consolidated adjusted EBITDA is less than 2.0 to 1, in which case there is no such limitation on amount. As of June 30, 2021 and December 31, 2020, the Company was in compliance with all of the Credit Facility covenants. The Term Loans have quarterly principal amortization during their five year terms, with 5.0 % amortization of the principal balance due in years 1 and 2, 7.5 % in year 3, and 10.0 % in years 4 and 5, with the remaining principal amount due at maturity. During the six months ended June 30, 2021, the Company made quarterly amortization payments related to the Term Loans totaling $ 19.1 million. The Credit Facility is guaranteed by certain of the Company’s domestic subsidiaries and is secured by first priority liens on substantially all of the assets of the Company and the domestic subsidiary guarantors, subject to certain customary exclusions. The obligations of the Dutch borrower are guaranteed only by certain foreign subsidiaries on an unsecured basis. The Credit Facility required the Company to fix its variable interest rates on at least 20 % of its total Term Loans. In order to satisfy this requirement as well as to manage the Company’s exposure to variable interest rate risk associated with the Credit Facility, in November 2019, the Company entered into $ 170.0 million notional amounts of three year interest rate swaps at a base rate of 1.64 % plus an applicable margin as provided in the Credit Facility, based on the Company’s consolidated net leverage ratio. At the time the Company entered into the swaps, and as of June 30, 2021, the aggregate interest rate on the swaps, including the fixed base rate plus an applicable margin, was 3.1 %. See Note 18 of Notes to Condensed Consolidated Financial Statements. The Company capitalized $ 23.7 million of certain third-party debt issuance costs in connection with executing the Credit Facility. Approximately $ 15.5 million of the capitalized costs were attributed to the Term Loans and recorded as a direct reduction of long- term debt on the Company’s Condensed Consolidated Balance Sheet. Approximately $ 8.3 million of the capitalized costs were attributed to the Revolver and recorded within other assets on the Company’s Condensed Consolidated Balance Sheet. These capitalized costs are being amortized into interest expense over the five year term of the Credit Facility. As of June 30, 2021 and December 31, 2020, the Company had $ 9.6 million and $ 11.1 million, respectively, of debt issuance costs recorded as a reduction of long-term debt. As of June 30, 2021 and December 31, 2020, the Company had $ 5.1 million and $ 5.9 million, respectively, of debt issuance costs recorded within other assets. Industrial development bonds As of June 30, 2021 and December 31, 2020, the Company had fixed rate, industrial development authority bonds totaling $ 10.0 million in principal amount due in 2028 . These bonds have similar covenants to the Credit Facility noted above. Bank lines of credit and other debt obligations The Company has certain unsecured bank lines of credit and discounting facilities in one of its foreign subsidiaries, which are not collateralized. The Company’s other debt obligations primarily consist of certain domestic and foreign low interest rate or interest- free municipality-related loans, local credit facilities of certain foreign subsidiaries and capital lease obligations. Total unused capacity under these arrangements as of June 30, 2021 was approximately $ 40 million. In addition to the bank letters of credit described in the “Credit facilities” subsection above, the Company’s only other off-balance sheet arrangements include certain financial and other guarantees. The Company’s total bank letters of credit and guarantees outstanding as of June 30, 2021 were approximately $7 million. The Company incurred the following debt related expenses included within Interest expense, net, in the Condensed Consolidated Statements of Operations: Three Months Ended Six Months Ended June 30, June 30, 2021 2020 2021 2020 Interest expense $ 4,813 $ 5,951 $ 9,463 $ 13,663 Amortization of debt issuance costs 1,188 1,188 2,375 2,375 Total $ 6,001 $ 7,139 $ 11,838 $ 16,038 Based on the variable interest rates associated with the Credit Facility, as of June 30, 2021 and December 31, 2020, the amounts at which the Company’s total debt were recorded are not materially different from their fair market value.

General Discussion Of Derivative Instruments And Hedging Activities [Abstract]
Derivative Instruments And Hedging Activities Disclosure [Text Block]	Note 18 – Hedging Activities In order to satisfy certain requirements of the Credit Facility as well as to manage the Company’s exposure to variable interest rate risk associated with the Credit Facility, in November 2019, the Company entered into $ 170.0 million notional amounts of three year interest rate swaps.

Commitments and Contingencies Disclosure [Abstract]
Commitments And Contingencies Disclosure [Text Block]	Note 19 – Commitments and Contingencies The Company previously disclosed in its 2020 Form 10-K that AC Products, Inc. (“ACP”), a wholly owned subsidiary, has been operating a groundwater treatment system to hydraulically contain groundwater contamination emanating from ACP’s site, the principal contaminant of which is perchloroethylene. As of June 30, 2021, ACP believes it is close to meeting the conditions for closure of the groundwater treatment system, but continues to operate this system while in discussions with the relevant authorities. As of June 30, 2021, the Company believes that the range of potential-known liabilities associated with the balance of the ACP water remediation program is approximately $ 0.1 million to $ 1.0 million. The low and high ends of the range are based on the length of operation of the treatment system as determined by groundwater modeling. Costs of operation include the operation and maintenance of the extraction well, groundwater monitoring and program management. The Company previously disclosed in its 2020 Form 10-K that an inactive subsidiary of the Company that was acquired in 1978 sold certain products containing asbestos, primarily on an installed basis, and is among the defendants in numerous lawsuits alleging injury due to exposure to asbestos. During the three and six months ended June 30, 2021, there have been no significant changes to the facts or circumstances of this previously disclosed matter, aside from on-going claims and routine payments associated with this litigation. Based on a continued analysis of the existing and anticipated future claims against this subsidiary, it is currently projected that the subsidiary’s total liability over the next 50 years for these claims is approximately $ 0.4 million (excluding costs of defense). The Company previously disclosed in its 2020 Form 10-K that it is party to certain environmental matters related to certain domestic and foreign properties currently or previously owned by Houghton. These environmental matters primarily require the Company to perform long-term monitoring as well as operating and maintenance at each of the applicable sites. During the three and six months ended June 30, 2021, there have been no significant changes to the facts or circumstances of these previously disclosed matters, aside from on-going monitoring and maintenance activities and routine payments associated with each of the sites. The Company continually evaluates its obligations related to such matters, and based on historical costs incurred and projected costs to be incurred over the next 28 years, has estimated the present value range of costs for all of the Houghton environmental matters, on a discounted basis, to be between approximately $ 5.5 million and $ 6.5 million as of June 30, 2021, for which $ 6.0 million was accrued within other accrued liabilities and other non-current liabilities on the Company’s Condensed Consolidated Balance Sheet as of June 30, 2021. Comparatively, as of December 31, 2020, the Company had $ 6.0 million accrued for with respect to these matters. The Company believes, although there can be no assurance regarding the outcome of other unrelated environmental matters, that it has made adequate accruals for costs associated with other environmental problems of which it is aware. Approximately $ 0.1 million was accrued as of both June 30, 2021 and December 31, 2020, to provide for such anticipated future environmental assessments and remediation costs. The Company previously disclosed in its 2020 Form 10-K that one of the Company’s subsidiaries received a notice of inspection from a taxing authority in a country where certain of its subsidiaries operate which related to a non-income (indirect) tax that may be applicable to certain products the subsidiary sells. To date, the Company has not received any assessment from the authority related to potential liabilities that may be due from the Company’s subsidiary. Consequently, there is substantial uncertainty with respect to the Company’s ultimate liability with respect to this indirect tax, as the application of this tax in its given market is ambiguous and interpreted differently among other peer companies and taxing authorities. The Company, with assistance from independent experts, has performed an evaluation of the applicability of this indirect tax to the Company’s subsidiaries in this country. During the six months ended June 30, 2021 and through the date of this Report, there have been no significant changes to the facts or circumstances of this previously disclosed matter, aside from on-going discussions between the Company and the taxing authority related to this notice of inspection and independent testing conducted by third-party consultants at the direction of the Company and the taxing authority to determine if the Company’s products have contents which subject them to this indirect tax. Based on all of the information available to the Company at this time, as of June 30, 2021, the Company has recorded a liability of $ 1.8 million in other accrued liabilities, which reflects the Company’s current best estimate of probable indirect tax owed, including interest and taking into account applicable statutes of limitations. Because these amounts in part relate to a Houghton entity acquired in the Combination and for periods prior to the Combination, the Company has submitted an indemnification claim with Houghton’s former owners related to this potential indirect tax liability. The Company recorded a receivable in other assets for approximately $ 1.1 million, which reflects the amount of the initial recorded liability for which the Company anticipates being indemnified. As noted, the Company believes there is substantial uncertainty with respect to its ultimate liability given the ambiguous application of this indirect tax. At this time, the Company’s current best estimate of a potential range for possible assessments, including additional amounts that may be assessed under these indirect tax laws, would be $ 0 to approximately $ 40 million, which is net of approximately $ 11 million of estimated income tax deductions and approximately $ 22 million of applicable rights to indemnification from Houghton’s former owners. During the first six months of 2021, one of the Company’s Brazilian subsidiaries received a notice that it had prevailed on an existing legal claim in regard to certain non-income (indirect) taxes that had been previously charged and paid. The matter specifically relates to companies’ rights to exclude the state tax on goods circulation (a valued-added-tax or VAT equivalent, known in Brazil as “ICMS”) from the calculation of certain additional indirect taxes (specifically the program of social integration (“PIS”) and contribution for the financing of social security (“COFINS”)) levied by the Brazilian States on the sale of goods. In May 2021, the Brazilian Supreme Court concluded that ICMS should not be included in the tax base of PIS and COFINS, and confirmed the methodology for calculating the PIS and COFINS tax credit claims to which taxpayers are entitled. The Company’s Brazilian entities had previously filed legal or administrative disputes on this matter and are entitled to receive tax credits and interest dating back to five years preceding the date of their legal claims. As a result of these court rulings in the first six months of 2021, the Company recognized non-income tax credits of 67.0 million BRL or approximately $ 13.3 million, which includes approximately $ 8.4 million for the PIS and COFINS tax credits as well as interest on these tax credits of $ 4.9 million. The tax credits to which the Company’s Brazilian subsidiaries are entitled are claimable once registered with the Brazilian tax authorities and the Company anticipates completing this step during the second half of 2021. These tax credits can be used to offset future Brazilian federal taxes and the Company currently anticipates using the full amount of credits during the five year period of time permitted. In connection with obtaining regulatory approvals for the Combination, certain steel and aluminum related product lines of Houghton were divested on August 1, 2019. In July 2021, the entity that acquired these divested product lines submitted an indemnification claim for certain alleged losses in accordance with the terms of the Asset Purchase Agreement (“APA”) . Under the terms of the APA, the Company has 45 days to review the claim and respond , and as such, the Company is in the early stages of evaluating the merits of the alleged losses in the indemnification claim received. As of the date of this Report, the Company does not believe it is reasonably possible to determine or quantify any possible exposure. The Company is party to other litigation which management currently believes will not have a material adverse effect on the Company’s results of operations, cash flows or financial condition. In addition, the Company has an immaterial amount of contractual purchase obligations.

Basis of Presentation and Description of Business [Abstract]
Basis Of Accounting Policy [Policy Text Block]	Basis of Presentation As used in these Notes to Condensed Consolidated Financial Statements, the terms “Quaker,” “Quaker Houghton,” the “Company,” “we,” and “our” refer to Quaker Chemical Corporation (doing business as Quaker Houghton), its subsidiaries, and associated companies, unless the context otherwise requires. As used in these Notes to Condensed Consolidated Financial Statements, the term Legacy Quaker refers to the Company prior to the closing of its combination with Houghton International, Inc. (“Houghton”) (herein referred to as the “Combination”). The condensed consolidated financial statements included herein are unaudited and have been prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP”) for interim financial reporting and the United States Securities and Exchange Commission (“SEC”) regulations. Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to such rules and regulations. In the opinion of management, the financial statements reflect all adjustments which are necessary for a fair statement of the financial position, results of operations and cash flows for the interim periods. The results for the six months ended June 30, 2021 are not necessarily indicative of the results to be expected for the full year. These financial statements should be read in conjunction with the Company’s Annual Report filed on Form 10-K for the year ended December 31, 2020 (the “2020 Form 10-K”).
Segments [Policy Text Block]	The Company’s operating segments, which are consistent with its reportable segments, reflect the structure of the Company’s internal organization, the method by which the Company’s resources are allocated and the manner by which the chief operating decision maker assesses the Company’s performance. The Company has four reportable segments: (i) Americas; (ii) EMEA; (iii) Asia/Pacific; and (iv) Global Specialty Businesses. The three geographic segments are composed of the net sales and operations in each respective region, excluding net sales and operations managed globally by the Global Specialty Businesses segment, which includes the Company’s container, metal finishing, mining, offshore, specialty coatings, specialty grease and Norman Hay businesses.
Revenue Recognition [Policy Text Block]	The Company applies the five-step model in the FASB’s guidance, which requires the Company to: (i) identify the contract with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when, or as, the Company satisfies a performance obligation. Refer to the Company’s 2020 Form 10-K for additional information on the Company’s revenue recognition policies, including its practical expedients and accounting policy elections. The Company recognizes a contract asset or receivable on its Condensed Consolidated Balance Sheet when the Company performs a service or transfers a good in advance of receiving consideration. A receivable is the Company’s right to consideration that is unconditional and only the passage of time is required before payment of that consideration is due. A contract asset is the Company’s right to consideration in exchange for goods or services that the Company has transferred to a customer. The Company had no material contract assets recorded on its Condensed Consolidated Balance Sheets as of June 30, 2021 or December 31, 2020. A contract liability is recognized when the Company receives consideration, or if it has the unconditional right to receive consideration, in advance of performance. A contract liability is the Company’s obligation to transfer goods or services to a customer for which the Company has received consideration, or a specified amount of consideration is due, from the customer. The Company’s contract liabilities primarily represent deferred revenue recorded for customer payments received by the Company prior to the Company satisfying the associated performance obligation. Deferred revenues are presented within other current liabilities in the Company’s Condensed Consolidated Balance Sheets. The Company had approximately $ 4.3 million and $ 4.0 million of deferred revenue as of June 30, 2021 and December 31, 2020, respectively. For the six months ended June 30, 2021, the Company satisfied all of the associated performance obligations and recognized into revenue the advance payments received and recorded as of December 31, 2020.
Revenue From Contract With Customer [Policy Text Block]	As part of the Company’s Fluidcare business, certain third-party product sales to customers are managed by the Company. Where the Company acts as a principal, revenues are recognized on a gross reporting basis at the selling price negotiated with its customers. Where the Company acts as an agent, revenue is recognized on a net reporting basis at the amount of the administrative fee earned by the Company for ordering the goods.
Goodwill And Intangible Assets, Goodwill, Policy [Policy Text Block]	Goodwill and intangible assets that have indefinite lives are not amortized and are required to be assessed at least annually for impairment. The Company completes its annual goodwill and indefinite-lived intangible asset impairment test during the fourth quarter of each year. The Company continuously evaluates if triggering events indicate a possible impairment in one or more of its reporting units or indefinite-lived or long-lived assets.
Lessee Leases [Policy Text Block]	The Company determines if an arrangement is a lease at its inception. This determination generally depends on whether the arrangement conveys the right to control the use of an identified fixed asset explicitly or implicitly for a period of time in exchange for consideration. Control of an underlying asset is conveyed if the Company obtains the rights to direct the use of, and obtains substantially all of the economic benefits from the use of, the underlying asset. Lease expense for variable leases and short-term leases is recognized when the obligation is incurred.
Credit Loss Financial Instrument [Policy Text Block]	As previously disclosed in the Company’s 2020 Form 10-K, during 2020, the Company adopted, as required, an accounting standard update related to the accounting and disclosure of credit losses effective January 1, 2020. The Company recognizes an allowance for credit losses, which represents the portion of its trade accounts receivable that the Company does not expect to collect over the contractual life, considering past events and reasonable and supportable forecasts of future economic conditions. The Company’s allowance for credit losses on its trade accounts receivables is based on specific collectability facts and circumstances for each outstanding receivable and customer, the aging of outstanding receivables, and the associated collection risk the Company estimates for certain past due aging categories, and also, the general risk to all outstanding accounts receivable based on historical amounts determined to be uncollectible. The Company does not have any off-balance-sheet credit exposure related to its customers.

- Definition

Includes, but is not limited to, methodology used to estimate allowance for credit loss, how writeoff of uncollectible amount is recognized, and determination of past due status and nonaccrual status.

Restructuring Cost and Reserve [Abstract]
Restructuring And Related Cost Description	The Company’s management approved a global restructuring plan (the “QH Program”) as part of its plan to realize certain cost synergies associated with the Combination in the third quarter of 2019. The QH Program includes restructuring and associated severance costs to reduce total headcount by approximately 400 people globally, as well as plans for the closure of certain manufacturing and non-manufacturing facilities. The exact timing and total costs associated with the QH Program will depend on a number of factors and is subject to change; however, the Company currently expects reduction in headcount and site closures to continue to occur throughout 2021 and into 2022 under the QH Program and estimates that anticipated cost synergies realized from the QH Program will approximate one-times the restructuring costs incurred. Employee separation benefits will vary depending on local regulations within certain foreign countries and will include severance and other benefits.
Restructuring And Related Cost Expected Number Of Positions Eliminated	400

- Definition

Accumulated change in equity from transactions and other events and circumstances from non-owner sources, net of tax effect, at period end. Excludes Net Income (Loss), and accumulated changes in equity from transactions resulting from investments by owners and distributions to owners. Includes foreign currency translation items, certain pension adjustments, unrealized gains and losses on certain investments in debt and equity securities, other than temporary impairment (OTTI) losses related to factors other than credit losses on available-for-sale and held-to-maturity debt securities that an entity does not intend to sell and it is not more likely than not that the entity will be required to sell before recovery of the amortized cost basis, as well as changes in the fair value of derivatives related to the effective portion of a designated cash flow hedge.
