Abstract
A cosmetic composition in the form of an aerosol spray for hair control contains a solvent; a film-forming tetrapolymer resulting from the copolymerization of (a) 5 to 10 wt. % acrylic acid, (b) 20 to 52 wt. % N,N-dimethylacrylamide, (c) 3 to 28 wt. % of N-tert-butylacrylamide, and (d) 20 to 45 wt. % ethyl methacrylate, the carboxylic acid functions of the tetrapolymer being at least partially neutralized with a mineral or organic base; and at least one non-halogen propellant gas. This spray provides excellent hair control, and the film-forming substance does not cause stickiness of the hair over time and is easily eliminated by washing with a shampoo.
