摘要

Cosmetic composition in the form of an aerosol lacquer. …??It contains, in a solvent, as a film-forming substance, a tetrapolymer resulting from the copolymerisation: … …  (a) of 5 to 10 % by weight of acrylic acid, …  (b) of 20 to 52 % by weight of N,N-dimethylacrylamide, …  (c) of 3 to 28 % by weight of N-tert-butylacrylamide, and …  (d) of 20 to 45 % by weight of ethyl methacrylate, … the carboxylic acid functional groups of the said tetrapolymer being neutralised, partially or completely, with the aid of an inorganic or organic base and at least one nonhalogenated compound as propellant gas. …??This lacquer permits an excellent fixing of the hair, the film-forming substance having no tacky effect with time and being easily removed by washing with the aid of a shampoo.
