Abstract

The present invention relates to a composition comprising, in at least one physiologically acceptable volatile medium: (a) at least one cationic polysaccharide; (b) at least one crosslinker having three or more acid groups or a salt thereof; (c) at least one powder; and (d) at least one polyol, wherein the (c) powder is insoluble in the physiologically acceptable volatile medium. The composition can form a film including a DIC-gel and a powder wherein the distribution of the powder in the film can be more even or more uniform.

Claims (24)

1 . A composition, comprising, in at least one physiologically acceptable volatile medium:

(a) at least one cationic polysaccharide;

(b) at least one crosslinker having three or more acid groups or a salt thereof selected from phytic acid and salts thereof;

(c) at least one powder; and

(d) at least one polyol selected from the group consisting of glycerin, ethyleneglycol, polyethyleneglycol, propyleneglycol, dipropyleneglycol, butyleneglycol, pentyleneglycol hexyleneglycol and mixtures thereof,

wherein

the amount of the (a) cationic polysaccharide(s) in the composition is from 0.01% to 5% by weight,

the amount of the (b) crosslinker(s) having three or more acid groups or a salt(s) thereof in the composition is from 0.001% to 5% by weight,

the amount of the (c) powder(s) in the composition is from 0.1% to 25% by weight, relative to the total weight of the composition,

the amount of the (d) polyol(s) in the composition is from 1% to 10% by weight, relative to the total weight of the composition,

the (a) cationic polysaccharide(s) and the (b) crosslinker(s) having three or more acid groups or a salt thereof form a dynamically and ionically crosslinked gel, and

the (c) powder is insoluble in the physiologically acceptable volatile medium.

2 . The composition according to claim 1 , wherein the (a) cationic polysaccharide is selected from cationic cellulose polymers.

3 . The composition according to claim 1 , wherein the (a) cationic polysaccharide has at least one quaternary ammonium group.

4 . The composition according to claim 1 , wherein the (a) cationic polysaccharide is selected from the group consisting of polyquaternium-4, polyquaternium-10, polyquaternium-24, polyquaternium-67, and a mixture thereof.

5 . The composition according to claim 1 , wherein the amount of the (a) cationic polysaccharide(s) in the composition is from 0.05% to 5% by weight, relative to the total weight of the composition.

6 . The composition according to claim 1 , wherein the amount of the (b) crosslinker(s) having three or more acid groups or a salt(s) thereof in the composition is from 0.05% to 5% by weight, relative to the total weight of the composition.

7 . The composition according to claim 1 , wherein the (c) powder is selected from pigments, fillers, UV filters and mixtures thereof.

8 . The composition according to claim 1 , wherein the amount of the (c) powder(s) in the composition is from 0.5% to 20% by weight, relative to the total weight of the composition.

9 . The composition according to claim 1 , wherein the (d) polyol is selected from the group consisting of dipropyleneglycol, butyleneglycol and a mixture thereof.

10 . The composition according to claim 1 , wherein the composition is a skin cosmetic composition.

11 . A cosmetic process for skin, comprising

applying to the skin the composition according claim 1 ; and drying the composition to form a cosmetic film on the skin.

12 . The composition according to claim 1 , wherein the amount of the (c) powder(s) in the composition is from 1% to 15% by weight, relative to the total weight of the composition.
