Abstract:
A single phase autophobic hairspray composition comprising:a) 0.5% to 10% by weight of a film-forming hairspray resin; b) 10 to 60% by weight of a mixed propellant system consisting of (C1-C4 alkyl ether) and a C3-C5 alkane selected from the group consisting of propane, isobutane, n-butane, and mixtures thereof; c) 0.01% to 1.0% by weight of an autophobic hairspray additive selected from the group consisting of: (i) alkyl-pendant silicone copolyols of formula (I): â€ƒwhere m and n are integers of from 0 to 50, and x and y are integers chosen to give the copolyol a molecular weight of at least 600; Z is hydrogen or a C1-4 alkyl radical; Wherein Me stands for methyl; (ii) dimethicone copolyols of formula (II): â€ƒwhere n is an integer chosen to give the copolyol a molecular weight of at least 600; x and xâ€² are integers of from 1 to 12; a, aâ€², b, bâ€² are integers of from 0 to 50, R is hydrogen or a C1-4 alkyl radical; and wherein me stands for methyl; (iii) polydimethicone copolyols of formula (III): â€ƒwhere x and n are integers chosen to give the copolyol a molecular weight of a least 500; y is an integer of from 1 to 12, and a and b are integers of from 0 to 50; and wherein me stands for methyl; (iv) alkyl ethoxylates; and (v) fluorosurfactants which imparts autophobic behavior to the hairspray composition, and d) 10% to 25% by weight water.
