Ammonium Acrylates Copolymer

Ammonium Acrylates Copolymer is the ammonium salt form of an acrylic acid based polymer used to thicken formulas, hold pigment in place, and help mascara or liquid liner form a flexible film once it dries. CIR reviewed the acrylates copolymer family and concluded they are safe in current practices of use, and a 30% concentration of the material tested as practically nonirritating.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
