Cosmetic Hazardous Ingredient Right to Know Act of 2025

The Cosmetic Hazardous Ingredient Right to Know Act of 2025 amends the Federal Food, Drug, and Cosmetic Act to sharply increase transparency around cosmetic ingredients. It requires brand owners to publicly disclose, via a master list maintained by the FDA and on their own websites, which ingredients are present in cosmetics and where those ingredients appear on government or international hazard lists. It also creates mandatory labeling requirements for cosmetics sold in interstate commerce, requiring a full ingredient listing (including fragrance and flavor components) and specific health hazard disclosures linked to those ingredients. The bill sets clear timelines (1 year for website disclosures; 2 years for product labeling) and establishes enforcement mechanisms that treat failures to disclose as adulterated or misbranded cosmetics. States can implement stricter rules, but federal rules govern the baseline, with careful attention to fragrance and flavor ingredients and the broad “hazard” lists referenced. In short, the act aims to give consumers and professionals easier access to information about potentially hazardous cosmetic ingredients, and to place a structured, multi-list hazard framework (from U.S. and international sources) at the center of how cosmetics are labeled and marketed.
