Cosmetic Supply Chain Transparency Act of 2025

This bill would require cosmetic suppliers to provide brand owners with detailed safety information about ingredients, including environmental and health hazards, chemical properties, and testing results. It creates a new FDA list of "nonfunctional constituents" (chemicals with no purpose in the product but potentially harmful to health or the environment) and mandates testing for these substances. Suppliers must provide certificates of analysis showing levels of these substances before selling to brand owners. The bill also establishes recordkeeping requirements for the entire cosmetic supply chain to facilitate recalls or investigations. These requirements apply to cosmetic manufacturers, suppliers, and brand owners, with the FDA responsible for implementation and enforcement.
