Illinois has enacted the Chemicals in Cosmetic Products Act, introducing one of the most significant state-level cosmetic ingredient restrictions in the United States. Beginning July 1, 2028, cosmetic products manufactured, distributed, or sold in Illinois may not contain 24 specifically identified intentionally added chemicals, including formaldehyde, mercury, certain phthalates, parabens, and per- and polyfluoroalkyl substances (PFAS).
The legislation reflects the growing trend of state-level chemical regulations designed to improve consumer safety while encouraging manufacturers to adopt safer formulations and stronger product stewardship practices. Cosmetic companies should proactively evaluate ingredient portfolios, reformulate affected products where necessary, strengthen supplier verification programs, and enhance regulatory intelligence to ensure continued market access.
The law also provides a limited exemption for technically unavoidable trace quantities when manufacturers can demonstrate that products were manufactured using processes intended to comply with the Act.
Illinois joins a growing number of U.S. states implementing stricter chemical safety requirements for cosmetic products.
Several factors are driving these regulatory developments:
