Autophobic silicone copolyols in hairspray compositions

Claim 1

An aerosol hairspray composition having improved body consisting essentially of from 0.5% to 8.0% by weight of an ethanol soluble hairspray resin dissolved in a sufficient amount of an ethanol solvent system to render the composition sprayable in aerosol form, said composition further containing an effective amount of an autophobic silicone copolyol to cause the sprayed film to contract on the hair at between 20° C. to 37° C. rather than to spread into an even film upon drying, said silicone copolyol consisting essentially of organosiloxy units selected from the group consisting of dimethylsiloxy units, CH 3 SiO(C x H 2x )(OCH 2 CH 2 ) y (OCHCH 3 CH 2 ) z OR, (CH 3 ) 2 SiO(C x H 2x )(OCH 2 CH 2 ) y (OCHCH 3 CH 2 ) z OR, and trimethylsiloxy units, and having a number average molecular weight of about 1500 to 6000 wherein x has a value of from 1 to 12, R is hydrogen or alkyl of 1 to 4 carbon atoms, y is greater than or equal to 1 and z is greater than or equal to 0 and the sum of y+z and the amount of dimethylsiloxy units and trimethylsiloxy units present is such that the silicone copolyol causes an ethanolic solution of the hairspray resin to contract on the hair rather to spread into an even film at 20° C. to 37° C. upon drying and a 0.1% by weight solution of the silicone copolyol in water has a cloud point of less than 30° C. and said ethanol solvent system consists essentially of at least 70% by weight of ethanol and any remaining solvent is selected from the group consisting of water. R 1 OH where R 1 is an alkyl of 3 or 4 carbon atoms, and mixtures thereof.
