TECHNOLOGY FOCUS - POLYMERS - Preferred Components: The amphoteric polymer is a copolymer of N-octyl acrylamide, (meth)acrylic acid or tert-butyl aminoethyl methacrylate and comprised in (I) at a concentration of 0.5-10 % by weight calculated to total composition excluding propellant gas.The nonionic polymer is vinylpyrrolidone/vinylacetate copolymer or polyvinylpyrrolidone, vinylpyrrolidone/vinylacetate/vinylpropionate copolymer and comprised in (I) at a concentration of 0.05-2 % by weight calculated to total composition excluding propellant gas.Preferred Composition: (I) comprise 80 % water by weight calculated to total composition excluding propellant gas. The ratio of non-ionic polymer and amphoteric polymer is 1:3-1:15. The concentration of propellant gas mixture is 2-30 % by weight calculated to total composition and at a weight ratio of 2-4C alkanes and/or haloalkanes or their mixtures and dimethylether between 1:2-1:5. (I) further comprises a surfactant (non-ionic, cationic, amphoteric or zwitterionic) and at a concentration lower than 2% by weight, calculated to total composition excluding propellant gas. (I) contains (all values are by weight): octylacrylamide/acrylates/butylaminoethyl methacrylate copolymer (2 %), vinylpyrrolidone/vinylacetate copolymer (0.25 %), cetrimoniumchloride (0.15 %), polyoxyethylene glycol-40 hydrogenated castor oil (0.20 %) and fragrance (0.20 %) in water without any added organic solvent at pH 8. 5 (preferably 7-8.5) adjusted with aminomethylpropanol and confectioned into an aerosol can with aqueous composition (80 %) with n-butane (4 w.%) and dimethylether (16 wt.%) or isobutane (5 %) and dimethylether (15 %) as propellants.Preferred Process: (I) has a pH 6.5-9. The hair is washed with a cleansing composition, then treated with preferably a rinse off conditioner, and towel dried before application of (I). EXAMPLE - Typical styling composition comprises (wt.%): octylacrylamide/acrylates/ butylaminoethyl methacrylate copolymer (2); vinylpyrrolidone/vinylacetate copolymer (0.25); cetrimoniumchloride (0.15); fragrance (0.20); polyoxyethylene glycol-40 hydrogenated castor oil (0.20 %); aminomethylpropanol (quantum satis (q.s) pH 8.5); water (add 100 %) and filling ratio are bulk (80); n-butane (4 %) and dimethylether (16%).
