Acrylates/t-Butylacrylamide Copolymer
Acrylates/t-Butylacrylamide Copolymer is a film-forming polymer used in UK beauty products to help makeup, hairspray and skincare stay put. It creates a flexible, breathable layer on skin or hair that improves wear time and water resistance without feeling stiff or heavy.
How it works in skincare
In cosmetics and skincare this synthetic copolymer works by forming a thin, invisible film on the surface of skin or hair after the product dries. It helps bind pigments and active ingredients in place, enhances water and transfer resistance, and improves the overall texture and longevity of formulations such as mascaras, eyeliners, sunscreens and styling sprays.
