About VA/CROTONATES COPOLYMER

A film-forming polymer used in hair styling products — it provides hold and shine while also working as an antistatic agent to tame flyaways.

Detailed Analysis

VA/Crotonates Copolymer (CAS 25609-89-6) is a synthetic copolymer of vinyl acetate and crotonic acid (2-butenoic acid). It functions as an antistatic agent, binder, film-former, and hair fixative in cosmetic formulations. The polymer forms a clear, flexible film on hair that provides styling hold and shine. The CIR Expert Panel has reviewed vinyl acetate-based copolymers and found them safe in cosmetics. Residual monomer content (vinyl acetate, crotonic acid) should be minimized as the free monomers are more irritating than the finished polymer.
