Expert Verdict

CRITICAL: Contains PFAS (perfluorononylethyl group) classified as per- or polyfluoroalkyl substance. ECHA universal PFAS restriction will likely ban this ingredient in EU cosmetics. Already banned under California AB 2771 as intentionally added PFAS. Environmental persistence and potential bioaccumulation present significant safety concerns. CIR review of dimer dilinoleates did not cover this perfluorinated variant. Major brand and reputational risk.
