Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying interim Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and the related notes included in our 2021 Annual Report on Form 10-K (“2021 Form 10-K”). The interim Consolidated Financial Statements are unaudited. In addition, certain information and footnote disclosures normally included in financial statements prepared in accordance with generally accepted accounting principles in the United States of America have been condensed or omitted, if not materially different from the 2021 Form 10-K. The year-end balance sheet data included in this Form 10-Q was derived from the audited financial statements. In the opinion of management, all adjustments, which consist of normal recurring adjustments necessary for a fair statement of the interim Consolidated Financial Statements, have been made. On February 1, 2021 (the “Closing Date”), pursuant to an Agreement and Plan of Merger (the “Merger Agreement”), the Company completed the combination (the "Merger") of IFF and DuPont de Nemours, Inc (“DuPont”) nutrition and biosciences business (the “N&B Business”), which had been transferred to Nutrition and Biosciences, Inc., a Delaware corporation and wholly owned subsidiary of DuPont ("N&B") in a Reverse Morris Trust transaction. See Note 3 for additional information. As a result, the Company’s Consolidated Financial Statements for the three months ended March 31, 2022 reflect the results of N&B for the full three months in the first quarter of 2022, whereas the three months ended March 31, 2021 reflect only two months of results of N&B in the first quarter of 2021.
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) requires management to make estimates and judgments that affect the amounts reported in the Consolidated Financial Statements and accompanying notes. The inputs into our judgments and estimates take into account the current economic implications of the novel coronavirus ("COVID-19") and the potential impairment of assets arising from the recent events in Russia and Ukraine on our critical and significant accounting estimates, including estimates associated with future cash flows that are used in assessing the risk of impairment of certain long-lived assets. Actual results could differ from those estimates.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In November 2021, the FASB issued Accounting Standards Update ("ASU") 2021-10, "Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance." The ASU requires annual disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy. This guidance is effective for all entities for annual periods beginning after December 15, 2021 and early adoption is permitted. The Company is currently evaluating the impact of this guidance, but does not expect this guidance to have a material impact on its Consolidated Financial Statements. In October 2021, the FASB issued Accounting Standards Update ("ASU") 2021-08, "Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers." The ASU is intended to provide specific guidance on how to recognize and measure acquired contract assets and liabilities from revenue contracts in a business combination. An acquirer needs to recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with Topic 606, Revenue from Contracts with Customers. At the acquisition date, an acquirer should account for the related revenue contracts in accordance with Topic 606 as if it had originated the contracts. To achieve this, an acquirer may assess how the acquiree applied Topic 606 to determine what to record for the acquired revenue contracts. This guidance is effective for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years, and early adoption is permitted, including adoption in an interim period. The Company is currently evaluating the impact of this guidance, but does not expect this guidance to have a material impact on its Consolidated Financial Statements. In January 2021, the FASB issued Accounting Standards Update ("ASU") 2021-01, "Reference Rate Reform (Topic 848): Scope." The ASU is intended to provide updates and responses to concerns over Topic 848 related to the cessation of reference rates in certain financial markets. Alternative reference rates that are more observable or transaction based have been identified and are being transitioned to in numerous jurisdictions globally, such as a receive-variable-rate, pay-variable-rate cross currency interest rate swap. This guidance is effective immediately for all entities, but does not apply to any contract modifications or new hedging relationships entered into after December 31, 2022. This guidance was adopted and does not have a material impact on the Company's Consolidated Financial Statements.
Receivable	Accounts Receivable The Company has various factoring agreements in the U.S. and The Netherlands under which it can factor up to approximately $250 million in receivables. In addition, the Company has factoring agreements sponsored by certain customers. Under all of the arrangements, the Company sells the receivables on a non-recourse basis to unrelated financial institutions and accounts for the transactions as a sale of receivables. The applicable receivables are removed from the Company's Consolidated Balance Sheets when the cash proceeds are received by the Company. The impact on cash provided by operations from participating in these programs was a decrease of $45 million for the three months ended March 31, 2022 and an increase of $29 million for the three months ended March 31, 2021. The cost of participating in these programs was approximately $1 million for both the three months ended March 31, 2022 and 2021.
Revenue	Revenue Recognition The Company recognizes revenue when control of the promised goods is transferred to its customers in an amount that reflects the consideration it expects to be entitled to in exchange for those goods. Sales, value added, and other taxes the Company collects are excluded from revenues. The Company receives payment in accordance with standard customer terms. See Note 11 for further details on revenues disaggregated by segment.
Property, Plant and Equipment, Policy	Property, Plant and Equipment Property, plant and equipment are recorded at cost. Depreciation is calculated on a straight-line basis, principally over the following estimated useful lives: buildings and improvements, 1 to 50 years; machinery and equipment, 1 to 40 years; information technology hardware and software, 1 to 23 years; and leasehold improvements which are included in buildings and improvements, the estimated life of the improvements or the remaining term of the lease, whichever is shorter.
Goodwill and Intangible Assets, Intangible Assets, Policy	Finite-Lived Intangible Assets Finite-lived intangible assets include customer relationships, patents, trade names, technological know-how and other intellectual property valued at acquisition and amortized on a straight-line basis over the following estimated useful lives: customer relationships, 10 to 27 years; patents, 11 to 15 years; trade names, 4 to 28 years; and technological know-how, 5 to 28 years. The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their carrying value may not be recovered. An estimate of undiscounted future cash flows produced by an asset or group of assets is compared to the carrying value to determine whether impairment exists. If assets are determined to be impaired, the loss is measured based on an estimate of fair value using various valuation techniques, including a discounted estimate of future cash flows. Recent Events in Russia and Ukraine The Company maintains operations in both Russia and Ukraine and, additionally, exports products to customers in Russia and Ukraine from operations outside the region. In response to the events in Ukraine, the Company has limited the production and supply of ingredients in and to Russia to only those that meet the essential needs of people, including food, hygiene and medicine. During the first quarter of 2022, in connection with the events in Ukraine (including the impact of the invasion and the sanctions placed on Russia), the Company determined that certain assets should be tested for recoverability. In order to perform the test for recoverability, the Company prepared an estimate of the undiscounted cash flows for the applicable asset groups. The total amount of assets in the applicable asset groups identified, and to be tested for recoverability, was approximately $228 million, or less than 1% of total assets, of which approximately $210 million related to Russia. Based on the projections made, it was determined that no impairment existed in any of the asset groups as of March 31, 2022. The undiscounted cash flows were prepared under the assumption that the Company’s operations in Russia and Ukraine would continue to operate and that the Company would be able to continue to manufacture and sell products within Russia, subject to limiting our operations to servicing essential needs. The Company may incur impairment of such assets in the future if these assumptions change or circumstances worsen. As indicated above, the Company also recorded a charge of approximately $20 million related to expected credit losses on receivables from customers located in Russia and Ukraine (for both export and domestic sales) due to recent events in those countries. The Company will continue to evaluate its credit exposure related to Russia and Ukraine.

Sales, value added, and other taxes the Company collects are excluded from revenues. The Company receives payment in accordance with standard customer terms. See Note 11 for further details on revenues disaggregated by segment.

Property, Plant and Equipment, Policy

Property, Plant and Equipment

Property, plant and equipment are recorded at cost. Depreciation is calculated on a straight-line basis, principally over the following estimated useful lives: buildings and improvements, 1 to 50 years; machinery and equipment, 1 to 40 years; information technology hardware and software, 1 to 23 years; and leasehold improvements which are included in buildings and improvements, the estimated life of the improvements or the remaining term of the lease, whichever is shorter.

Goodwill and Intangible Assets, Intangible Assets, Policy

The Company reviews long-lived assets for impairment when events or changes in business conditions indicate that their carrying value may not be recovered. An estimate of undiscounted future cash flows produced by an asset or group of assets is compared to the carrying value to determine whether impairment exists. If assets are determined to be impaired, the loss is measured based on an estimate of fair value using various valuation techniques, including a discounted estimate of future cash flows.

Recent Events in Russia and Ukraine

The Company maintains operations in both Russia and Ukraine and, additionally, exports products to customers in Russia and Ukraine from operations outside the region. In response to the events in Ukraine, the Company has limited the production and supply of ingredients in and to Russia to only those that meet the essential needs of people, including food, hygiene and medicine.

During the first quarter of 2022, in connection with the events in Ukraine (including the impact of the invasion and the sanctions placed on Russia), the Company determined that certain assets should be tested for recoverability. In order to perform the test for recoverability, the Company prepared an estimate of the undiscounted cash flows for the applicable asset groups. The total amount of assets in the applicable asset groups identified, and to be tested for recoverability, was approximately $228 million, or less than 1% of total assets, of which approximately $210 million related to Russia. Based on the projections made, it was determined that no impairment existed in any of the asset groups as of March 31, 2022. The undiscounted cash flows were prepared under the assumption that the Company’s operations in Russia and Ukraine would continue to operate and that the Company would be able to continue to manufacture and sell products within Russia, subject to limiting our operations to servicing essential needs. The Company may incur impairment of such assets in the future if these assumptions change or circumstances worsen.

As indicated above, the Company also recorded a charge of approximately $20 million related to expected credit losses on receivables from customers located in Russia and Ukraine (for both export and domestic sales) due to recent events in those countries. The Company will continue to evaluate its credit exposure related to Russia and Ukraine.
