Abstract
The use of at least 0.5% by weight water as an additive in a hairspray composition for the purpose of inducing or enhancing autophobic behavior in the hairspray composition.
Claims11
A hairspray composition comprising in addition to at least 5% by weight water:
- a) from 0.5% to 10% by weight of a hairspray resin;
- b) from 0 to 50% by weight of an aerosol propellant;
- and
- c) from 0.05% to 2% by weight of an autophobic hairspray surfactant or polymer, which is a surfactant or polymer which exhibits autophobic behaviour in conjunction with at least 0.5% water, and which is selected from the group consisting of:
- (i) dimethicone copolyols of formula (I):
- where n is an integer chosen to give the copolyol a molecular weight of at least 600;
- x and x′ are integers of from 1 to 12;
- a, a′, b, b′ are integers of from 0 to 50, and R is hydrogen or a C1-4 alkyl radical;
- and
- (ii) polydimethicone copolyols of formula (II):
- where x and n are integers chosen to give the copolyol a molecular weight of at least 500;
- y is an integer of from 1 to 12, and
- a and b are integers of from 0 to 50.
