In a move to bolster consumer safety, California is enhancing its regulations governing cosmetics with the introduction of Assembly Bill 496 (AB 496). This law updates the state’s 2020 Toxic-Free Cosmetics Act, which initially banned 24 chemicals from use in personal care products, by adding 26 chemicals to the list of prohibited ingredients. The bill, which comes into effect on January 1, 2027, builds upon existing legislation that prohibits the use of certain intentionally added ingredients in cosmetic products, a measure set to begin enforcement on January 1, 2025.

The list of prohibited ingredients includes those like lily aldehyde, acetaldehyde, and styrene, to name a few, which will be off-limits in cosmetic production starting in 2027. The bill also addresses a broad range of boron substances, perfluorooctane sulfonate (PFOS), and perfluorooctanoic acid (PFOA), among others. While these stringent regulations are in place, the bill acknowledges that trace quantities of these ingredients, stemming from any impurities of components or manufacturing and storage processes shall not lead to a violation of the new provisions.
