Abstract
Abstract Hair care and hair cosmetic preparations, i. e., aerosol hair sprays, hair conditioners, and hair setting lotions, etc. containing as the film-forming resin homo- and copolymers of Nvinyl pyrrolidone admixed with a quaternized copolymer of vinyl pyrrolidone and a vinyl monomer copolymerizable therewith, i. e., a di-loweralkyl aminoalkyl acrylate or methacrylate. Such compositions containing N-vinyl pyrrolidone polymers and the quaternized copolymer exhibit excellent adhesion and holding power when employed for hair care preparations.
