<p>Aqueous aerosol lacquer for holding and/or fixing hair. This lacquer contains, dissolved in water and as film-forming substance, a copolymer essentially consisting of repeating units derived from the polymerisation: (i) of at least one unsaturated sulphonic acid in a proportion of 30 to 90% by weight and having the following general formula: <IMAGE> in which: R1 represents a hydrogen atom or the CH3 radical, X represents -O- or -NH-, and Y represents a linear or branched alkylene chain having from 1 to 6 carbon atoms, and (ii) of at least one N-monoalkylacrylamide or methacrylamide in a proportion of 10 to 70% by weight and having the following general formula: <IMAGE> in which: R2 represents a hydrogen atom or the -CH3 radical and R3 represents a linear or branched alkyl radical having from 3 to 10 carbon atoms, the sulphonic acid functional groups of the said copolymer being neutralised in a proportion of 40 to 70% by triethanolamine, and the propellant for the said aerosol lacquer being dimethyl ether.</p> |
