Abstract
The invention relates to a styling composition packaged in an aerosol device, comprising from 45% to 65% by weight of a liquid phase containing, in dissolved or finely dispersed form in a cosmetically acceptable aqueous or aqueous-alcoholic liquid medium, at least one branched sulphonic polyester, and from 35% to 55% of dimethyl ether as propellant, the total water content of the liquid phase being between 65% and 99% by weight, and also to a styling process using such a composition.
Claims19
Styling composition packaged in an aerosol device, comprising
- from 45% to 65% by weight of a liquid phase containing, in dissolved or finely dispersed form in a cosmetically acceptable aqueous or aqueous-alcoholic liquid medium, at least one branched sulphonic polyester, and
- from 35% to 55% by weight of dimethyl ether as propellant,
- the total water content of the liquid phase being between 65% and 99% by weight.
Styling composition according to any one of the preceding claims, characterized in that the branched sulphonic polyester is a polymer formed by polycondensation
- (a) of at least one dicarboxylic acid not bearing a sulphonic function,
- (b) of at least one diol or a mixture of a diol and a diamine,
- (c) of at least one monomer comprising two reactive functions, which may be identical or different, chosen from hydroxyl, amino and carboxyl groups, and also bearing at least one sulphonic function, and
- (d) of at least one monomer comprising at least three reactive functions, which may be identical or different, chosen from hydroxyl, amino and carboxyl groups.
Styling composition according to any one of the preceding claims, characterized in that the branched sulphonic polyester represents from 0.2% to 15% and preferably from 0.5% to 10% of the total weight of the liquid phase of the styling composition.
Styling composition according to any one of the preceding claims, characterized in that the water content of the liquid phase is between 70% and 98% and preferably between 75% and 96% by weight.
Styling composition according to any one of the preceding claims, characterized in that it is a hair lacquer.
Process for styling by spraying a styling composition, packaged in an aerosol device, according to any one of the preceding claims, onto the hair.
