Cosmetics poised to be reformulated with lower toxic chemicals in the wake of new California law

[A California ban of toxic chemicals in cosmetics], signed by Gov. Gavin Newsom at the end of September, covers 24 chemicals, including mercury, formaldehyde and several types of per- and polyfluoroalkyl substances, known as PFAS. All the chemicals are carcinogenic or otherwise toxic — and advocates argue they have no place in beauty products.

When the law takes effect in 2025, it will mark the first major action to remove toxic substances from beauty products in almost a century. Federal regulation of cosmetics has not been updated meaningfully since 1938, and only 11 ingredients in personal care products are regulated by the Food and Drug Administration. By contrast, the European Union bans more than 1,600 cosmetic substances and ingredients from cosmetics.

The California law, passed by wide margins in both houses of the legislature, “is a milestone for cosmetic safety in the United States,” said Emily Rusch, executive director of the California Public Interest Research Group, which was heavily involved in shaping the bill.

“If you’re doing business in the United States, you’re doing business in California,” said Mike Thompson, senior vice president for government affairs at the council. “I would assume that this would really, in many ways, set up a new standard.”
