A proposed REACH Annex XVII restriction could end octocrylene's use as a UV filter in the EU, capping it at 0.001% w/w in finished cosmetics on environmental grounds. For global brands, formulators, contract manufacturers, and importers, this is a market-access exposure that reaches every sunscreen, SPF moisturiser, foundation, and SPF lip product in the portfolio.
