Verdict
Safe film-forming and opacifying polymer with negligible systemic absorption. CIR concluded safe as used when formulated to avoid irritation. EWG scores low for cancer, allergies, developmental toxicity; potential impurity/contamination concern. EU permitted with no restrictions. Not restricted under EU Cosmetics Regulation.
US Note
Not prohibited or restricted by FDA. Reported in FDA VCRP. CIR assessed acrylates copolymer class (incl. ammonium styrene/acrylates copolymer) as safe when formulated to be non-irritating (IJT 2002, amended 2019).
