What it does
This bill requires cosmetic manufacturers and suppliers to provide detailed safety and ingredient information to brand owners upon request, establishes an FDA list of harmful 'nonfunctional constituents' (impurities and byproducts) that must be tested for, and allows states to maintain or impose stricter cosmetic ingredient rules than federal standards. It also creates civil penalties up to $10,000 per day for non-compliance.
Why we flagged it
The bill's core function is mandating disclosure of cosmetic ingredients and contaminants to brand owners and the FDA, with testing requirements for harmful substances. It is fundamentally a transparency and safety-oversight measure, not a ban or prohibition.
What the text implies
- Compliance costs will likely be passed to consumers through higher cosmetic prices, disproportionately affecting lower-income shoppers who may have fewer affordable alternatives.
- The bill's reliance on existing lists (California Prop 65, EU REACH, IARC) means US cosmetic standards will de facto align with international regulations, potentially limiting product innovation or creating supply-chain friction for smaller manufacturers.
