Acrylamide/Ammonium Acrylate Copolymer
A film-forming polymer used in hair and skin products.
What it does
It’s a polymer made from acrylamide and ammonium acrylate. It binds a product together and helps hold hair in place.
The EU’s ingredient database lists it as a film former (leaves a film on skin) and a binder (holds the product together).European Commission, CosIng (© European Union, CC BY 4.0) · uses put in plain words by Drop ↗
The evidence, graded
expert consensusUS safety reviewers (2022) judged 16 acrylamide/acrylate copolymers, this one among them, safe as used. It binds, forms films and holds hair in place. They told makers to keep acrylamide, a raw material, under 5 ppm in finished products; this ingredient may itself hold 2 ppm of leftover acrylamide. Patch tests of it at 0.66% on 109 people and at 5% on 50 found no irritation or allergy. The data were too thin to judge it in airbrush makeup.Cherian 2022 · Cosmetic Ingredient Review ↗
