Abstract
Cosmetic compositions comprising, in a cosmetically acceptable medium, at least one aqueous emulsion of at least one silicone copolymer with a dynamic viscosity ranging from 1×106 to 100×106 cP and at least one non-cellulose thickener. This combination can give cosmetic properties, such as at least one of smoothness, lightness, and softness, without the phenomenon of regreasing keratin fibers. These compositions can be used for washing and/or conditioning a keratin material, such as the hair or the skin.
Claims104
A cosmetic composition comprising, in a cosmetically acceptable medium, at least one non-cellulose thickener and at least one aqueous emulsion comprising at least one silicone copolymer with a dynamic viscosity ranging from 1×106 to 100×106 cP, resulting from the addition reaction, in the presence of a catalyst, of at least:

- in which:
- R1, which may be identical or different, are independently chosen from groups that can react by chain addition reaction,
- R2 in formula (I), which may be identical or different, are independently chosen from alkyl, alkenyl, cycloalkyl, aryl, hydroxyl, and alkylaryl groups, and can optionally further comprise functional groups,
- n is an integer wherein the polysiloxane of formula (I) has a kinematic viscosity ranging from 1 to 1×106 mm2/s;
- and
- (b) at least one silicone compound comprising at least one and not more than two groups capable of reacting with the groups R1 of the polysiloxane (a), wherein:
