Expert Verdict

Acrylate monomers can cause skin irritation and sensitization upon direct contact; however, in cosmetics it is almost exclusively used in polymerized form (copolymers) where residual monomer levels are extremely low. A 22-carbon long-chain acrylate ester (C₂₅H₄₈O₂, MW 380.65 g/mol); the long alkyl chain imparts hydrophobicity, water resistance, and flexibility to polymer films; typically copolymerized with other acrylates/methacrylates for cosmetic applications
