Acrylates/Steareth-20 Methacrylate Copolymer is a versatile polymer used in cosmetic and personal care formulations. It functions as a film former, emulsifier, and texture enhancer in creams, lotions, sunscreens, and hair care products. This copolymer helps stabilize emulsions, improve water resistance, and enhance product aesthetics. Its polymeric structure also provides a smooth, long-lasting feel on skin and hair.
