Abstract
A protein-acrylate copolymer contains at least one nitrogen containing acrylic monomer. The nitrogen containing acrylic monomer preferably contains a tertiary or quaternary amine group, and particularly a quaternary amine group. The protein-acrylate copolymer can be produced by reacting hydrolyzed protein with at least one nitrogen containing acrylic monomer, preferably by free-radical polymerization. The protein-acrylate copolymer is suitable for use in personal care or cosmetic products, particularly in hair care products where it can increase volume to hair.
