Expert Verdict

CIR panel concluded acrylate/methacrylate copolymers are safe as cosmetic ingredients in current use concentrations. Residual monomers (cyclohexyl methacrylate, 2-ethylhexyl methacrylate) are potential sensitizers, so monomer levels must be controlled to very low ppm. Also listed in China's permitted cosmetics ingredient list (CFDA No. 3291).. This is the only polymer on this list. It produces a continuous, flexible, water-resistant film. The cyclohexyl methacrylate monomer contributes hardne...
