Acrylates/Dimethylaminoethyl Methacrylate Copolymer

What is Acrylates/Dimethylaminoethyl Methacrylate Copolymer?

Acrylates/Dimethylaminoethyl Methacrylate Copolymer is a synthetic, water-soluble polymer created from acrylate and dimethylaminoethyl methacrylate monomers. This cationic copolymer features positively charged groups, making it suitable for personal care products like hair fixatives, mascaras, eyeliners, and nail coatings. In formulations, it serves as a film former by depositing a sheer, flexible layer on skin, hair, or nails to boost adhesion, resist water, and maintain shape during wear. Its binding properties unite powders, pigments, and other components, enhancing the stability and smoothness of pressed or molded cosmetics. The polymer's design ensures easy rinse-off while providing hold without excessive rigidity, commonly appearing in styling gels, sprays, and long-wear makeup.
