This copolymer, made of styrene, acrylates and ammonium methacrylate is a water-resistant film-forming agent.
Copolymer compounds create a water-repellent base for products with waterproof qualities. They act by creating a thin flexible film that prevents water from washing the product away.
The synthetic polymers found in Lush products are in a solution, not in a solid or in a bead form. Depending on the type, they are water soluble or oil soluble. Lush have never used microbeads for exfoliation and never will. Styrene/Acrylates/Ammonium Methacrylate Copolymer has been proven safe for use on skin and hair.
