Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Legal Proceedings During the year ended September 30, 2024, the Company settled legal matters for certain class action advertising claims which resulted in a loss of $3.9. This was included in SG&A in the Consolidated Statement of Earnings and Comprehensive Income for the year ended September 30, 2024. During the year ended September 30, 2023, the Company settled a legal matter which resulted in a gain of $4.9 related to an intellectual property claim against a third party. This was included in SG&A in the Consolidated Statements of Earnings and Comprehensive Income. The Company received payment for the intellectual property claim settlement in fiscal 2023. Additionally, during the year ended September 30, 2023, the Company received a favorable court ruling regarding an international VAT matter, which the plaintiff has no ability to appeal. As the Company had previously recorded an accrual for this matter, based on its best estimate of the facts and circumstances at that time, the result of the favorable court ruling was a release of the reserve established which resulted in a gain of $2.2. This was included in SG&A in the Consolidated Statement of Earnings and Comprehensive Income in fiscal 2023. The Company and its subsidiaries are subject to a number of legal proceedings in various jurisdictions arising out of its operations during the ordinary course of business. Many of these legal matters are in preliminary stages and involve complex issues of law and fact and may proceed for protracted periods of time. The amount of liability, if any, from these proceedings cannot be determined with certainty. The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies when the incurrence of a loss is probable and can be reasonably estimated and discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued if such disclosure is necessary for its financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated. Based upon present information, the Company believes that its liability, if any, arising from such pending legal proceedings, asserted legal claims, and known potential legal claims which are likely to be asserted, is not reasonably likely to be material to its financial position, results of operations or cash flows, when taking into account established accruals for estimated liabilities. Government Regulation and Environmental Matters The operations of the Company are subject to various federal, state, local, and foreign laws and regulations intended to protect the public health and environment. Contamination has been identified at certain of the Company’s current and former facilities, as well as third-party waste disposal sites, and the Company is conducting investigation and remediation activities in relation to such properties. In connection with certain sites, the Company has received notices from the U.S. Environmental Protection Agency, state agencies and private parties, that it has been identified as a potentially responsible party (“PRP”) under the Comprehensive Environmental Response, Compensation and Liability Act of 1980 (“CERCLA”), and may be required to share in the cost of cleanup with respect to a number of federal “Superfund” sites. The Company may also be required to share in the cost of cleanup with respect to state-designated sites, and certain international locations, as well as any of its own properties. Accrued environmental costs at September 30, 2025 and 2024 were $7.7 and $7.9, respectively, and were recorded in Other Current Liabilities and Other Liabilities within the Consolidated Balance Sheets. The amount of the Company’s ultimate liability in connection with those sites may depend on many factors, including the volume and toxicity of material contributed to the site, the number of other PRPs and their financial viability, and the remediation methods and technology to be used. Total environmental capital expenditures and operating expenses are not expected to have a material effect on the Company’s total capital and operating expenditures, cash flows, earnings or competitive position. Current environmental spending estimates may be modified as a result of changes in the Company’s plans or its understanding of the underlying facts, changes in legal requirements, including any requirements related to global climate change, or other factors. Many European countries, as well as the European Union, have been very active in adopting and enforcing environmental regulations. As such, it is possible that new regulations may increase the risk and expense of doing business in such countries. Certain of the Company’s products are subject to regulation under the U.S. Federal Food, Drug and Cosmetic Act and are regulated by the U.S. Food and Drug Administration.
