This bill, known as the "No PFAS in Cosmetics Act," amends the Federal Food, Drug, and Cosmetic Act to establish a ban on the inclusion of intentionally added perfluoroalkyl or polyfluoroalkyl substances (PFAS) in cosmetic products. It provides a clear definition for PFAS as a class of fluorinated organic chemicals containing specific carbon atoms, and specifies that an "intentionally added" PFAS has a functional or technical effect or is an intentional breakdown product. The prohibition on these substances in cosmetics is slated to become effective on January 1, 2027 . Additionally, the legislation includes a conforming amendment to repeal a section of the Modernization of Cosmetics Regulation Act of 2022, streamlining the regulatory framework. This measure aims to enhance consumer safety by eliminating these potentially harmful chemicals from cosmetic formulations.
