Aerosol collar for hair fixation containing a tetrapolymer of acrylic acid, N-vinylpyrrolidone, N-tert, butylacrylamide and methacrylic acid ethyl ester.

摘要

This composition, in the form of aerosol lacquer in a solvent, contains as film-forming substance a tetrapolymer resulting from the copolymerisation of: (a) 4 to 6 % by weight of acrylic acid (AA), (b) 42 to 52 % by weight of N-vinylpyrrolidone (NVP), (c) 15 to 25 % by weight of N-tert-butylacrylamide (NtBA), and (d) 20 to 26 % by weight of ethyl methacrylate (EMA), the carboxylic acid functional groups of the said tetrapolymer being neutralised partially or completely with the aid of an inorganic or organic base, the propellent gas of the said lacquer being at least one nonhalogen compound. This lacquer has an excellent lacquering power and makes hair shiny and supple.
