As payments from the U.S. Pension Plan for this cash out offering exceeded the service and interest cost components of the U.S. Pension Plan expense for the year ended December 31, 2017, the Company recorded a settlement charge of approximately $1.9 million. This settlement charge represented the immediate recognition into expense of a portion of the unrecognized loss within AOCI on the balance sheet in proportion to the share of the projected benefit obligation that was settled by these payments. The gross pension benefit obligation was reduced by approximately $4.0 million as a result of these payments.

CY2018	us-gaap	Business Combination Separately Recognized Transactions Description BusinessCombinationSeparatelyRecognizedTransactionsDescription	In April 2017, Quaker entered into a share purchase agreement with Gulf Houghton Lubricants, Ltd. to purchase the entire issued and outstanding share capital of Houghton International, Inc. (“Houghton”) (herein referred to as “the Combination”). The shares will be bought for aggregate purchase consideration consisting of: (i) $172.5 million in cash; (ii) a number of shares of common stock, $1.00 par value per share, of the Company comprising 24.5% of the common stock outstanding upon the closing of the Combination; and (iii) the Company’s assumption of Houghton’s net indebtedness as of the closing of the Combination, which was approximately $690 million at signing. At closing, the total aggregate purchase consideration is dependent on the Company’s stock price and the level of Houghton’s indebtedness. The Company secured $1.15 billion in commitments from Bank of America Merrill Lynch and Deutsche Bank to fund the Combination and to provide additional liquidity, and has since replaced these commitments with a syndicated bank agreement (“the New Credit Facility”) with a group of lenders for $1.15 billion. The New Credit Facility is contingent upon and will not be effective until the closing of the Combination. During the fourth quarter of 2018, the Company extended the bank commitment for the New Credit Facility through March 15, 2019. The New Credit Facility is comprised of a $400.0 million multicurrency revolver, a $600.0 million USD term loan and a $150.0 million EUR equivalent term loan, each with a five-year term from the date the New Credit Facility becomes effective. The maximum amount available under the New Credit Facility can be increased by $200.0 million at the Company’s option if the lenders agree and the Company satisfies certain conditions. Borrowings under the New Credit Facility will bear interest at a base rate, LIBOR rate plus a margin, or Euribor rate plus a margin. The Company currently estimates the annual floating rate cost will be in the 3.75% to 4.0% range based on current market interest rates. The New Credit Facility will be subject to certain financial and other covenants, including covenants that the Company’s consolidated net debt to adjusted EBITDA ratio cannot exceed 4.25 to 1 and the Company’s consolidated adjusted EBITDA to interest expense ratio cannot be less than 3.0 to 1. Both the USD and EUR equivalent term loans will have quarterly principal amortization during their respective 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 amounts due at maturity. Until closing, the Company will incur certain interest costs paid to maintain the bank commitment (“ticking fees”), which began to accrue on September 29, 2017 and bear an interest rate of 0.30% per annum. The Company received regulatory approval for the Combination from China and Australia in 2017. In addition, at a shareholder meeting held during 2017, the Company’s shareholders overwhelmingly approved the issuance of the new shares of the Company’s common stock at closing of the Combination. The European Commission (“EC”) conditionally approved the Combination in December 2018, including the remedy proposed by Quaker and Houghton. The Company expects final approval from the EC once the final purchase agreement is in place between Quaker, Houghton, and the buyer of the divested product lines. The Company continues to be in productive discussions with the U.S. Federal Trade Commission (“FTC”), although the process is taking longer than anticipated. Given the time lapse since the Company’s initial filing, the FTC requested updated information as part of their approval process late in the fourth quarter of 2018. In addition, the government shutdown in the U.S. during the first quarter of 2019 extended the timeline to receive the final approval. Given current information, the Company estimates that FTC and EC final approval and closing of the combination will occur within the next few months.

CY2018	us-gaap	New Accounting Pronouncement Or Change In Accounting Principle Description NewAccountingPronouncementOrChangeInAccountingPrincipleDescription	Adoption of the revenue recognition guidance did not have a material impact on the Company’s reported earnings or cash flows, however, adoption did increase the amount and level of disclosures concerning the Company’s net sales and did result in one adjustment to the Company’s balance sheet. As a result of the Company’s impact assessment and adoption using the modified retrospective adoption approach, the Company recorded a cumulative effect of an accounting change as of January 1, 2018 to adjust the Company’s estimate of variable consideration relating to customers’ expected rights to return product. This adjustment resulted in an increase to other current liabilities of $1.0 million, an increase to non-current deferred tax assets of $0.2 million and a decrease to retained earnings of $0.8 million. There were no other impacts recorded as a result of adopting the revenue recognition guidance in 2018 or prior years and the Company expects the impact to be immaterial on an ongoing basis.

CY2018	kwr	Us Tax Reform Act USTaxReformAct	On December 22, 2017, the U.S. government enacted comprehensive tax legislation commonly referred to as U.S. Tax Reform. U.S. Tax Reform included multiple changes to the U.S. tax code with varying effects on the Company’s 2017 results, including, but not limited to, (i) a revaluation of the Company’s U.S. deferred tax assets and liabilities based upon the reduction of the U.S. federal statutory corporate income tax rate from 35% to 21% and (ii) implementation of a new system of taxation for non-U.S. earnings which eliminates U.S. federal income taxes on dividends from certain foreign subsidiaries and imposes a one-time transition tax on the deemed repatriation of undistributed earnings of certain foreign subsidiaries that is payable over eight years. U.S. Tax Reform also made changes to the U.S. tax code that have impacted 2018 and will impact future years, including, but not limited to, (i) reduction of the U.S. federal statutory corporate tax rate; (ii) elimination of the corporate alternative minimum tax; (iii) the creation of the base erosion anti-abuse tax, a new minimum tax; (iv) a general elimination of U.S. federal income taxes on dividends from foreign subsidiaries; (v) a new provision designed to tax global intangible low-taxed income (“GILTI”), which allows for the possibility of using foreign tax credits and a deduction of up to 50 percent to offset the income tax liability (subject to some limitations); (vi) a new limitation on deductible interest expense; (vii) the repeal of the U.S. production activity deduction; (viii) limitations on the deductibility of certain executive compensation; (ix) limitations on the use of foreign tax credits to reduce the U.S. income tax liability; (x) a reduction in the dividends received deduction from 70% to 50% (in the case of less-than-20%-owned subsidiaries) and from 80% to 65% (in the case of less-than-80%-owned subsidiaries); and (xi) limitations on net operating losses generated after December 31, 2017 to 80 percent of taxable income. Also, in 2017, the Securities and Exchange Commission issued guidance on accounting for the tax effects of U.S. Tax Reform and provided a one-year measurement period for companies to complete the accounting. The Company’s initial analysis of the impact of U.S. Tax Reform resulted in an incremental tax expense of $22.2 million recorded during the fourth quarter of 2017. U.S. Tax Reform reduced the U.S. federal statutory corporate tax rate from 35% to 21% effective January 1, 2018. Consequently, the Company recorded a decrease in U.S. net deferred tax assets of approximately $4.5 million with a corresponding net adjustment to deferred income tax expense during the fourth quarter of 2017. This initial estimate was not adjusted during 2018. The Transition Tax is a tax on previously untaxed accumulated and current earnings and profits of certain of the Company’s foreign subsidiaries as of either the November 2, 2017 or December 31, 2017 measurement date provided within U.S. Tax Reform. The Company made a reasonable estimate of its Transition Tax and recorded a gross provisional Transition Tax obligation during the fourth quarter of 2017 of $18.4 million, or $17.8 million, net of the impact of eliminating U.S. Federal income taxes on dividends from certain foreign subsidiaries received during 2017. Subsequent to numerous temporary regulations, notices, and other formal guidance published by the Internal Revenue Service (“IRS”), U.S. Treasury, and various state taxing authorities in 2018, the Company completed its accounting for the tax effects of U.S. Tax Reform as of December 22, 2018 and refined the total incremental tax expense related to U.S. Tax Reform to approximately $28.0 million. Based on proposed regulations published by the U.S. federal and state taxing authorities, the Company recorded a $2.5 million tax benefit to adjust its net Transition Tax to $15.3 million. The Company elected to pay its Transition Tax in installments over eight years as provided for in U.S. Tax Reform. In addition, the Company recorded deferred income tax expense of $0.3 million in 2018 related to the deductibility of certain executive compensation based on formal guidance issued by the IRS in 2018. As a result of the impacts from U.S. Tax Reform, the Company re-evaluated its global cash strategy resulting in a change to its indefinite reinvestment assertion attributable to a portion of its undistributed foreign earnings and recognized a deferred tax liability and corresponding deferred tax expense of $7.9 million, which primarily represents the Company’s estimate of the non-U.S. income taxes the Company will incur to ultimately remit those earnings to the U.S.
