Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer
Octylacrylamide/Acrylates/Butylaminoethyl Methacrylate Copolymer is a synthetic film-forming polymer used in UK hair and beauty products. It helps create flexible, long-lasting hold in hairsprays, gels and styling creams while improving water resistance. Shoppers will often see it listed in products promising strong yet touchable style that lasts all day.
How it works in skincare
In cosmetics and skincare this copolymer acts as a film-former and fixative, creating a thin, flexible layer on the hair shaft that holds styles in place without stiffness or flaking. It is particularly valued in aerosol and pump hairsprays, gels and mousses where it delivers humidity resistance and helps the product adhere evenly. The ingredient also contributes to the texture and spreadability of the formula, allowing for smooth application and a natural-looking finish that can be brushed out when desired.
