Abstract

The present invention is directed to a cosmetic composition that is moisturizing, hydrating, refreshing and long wearing, and has an unique texture and feel comprising a cellulosic gelling agent, an oil-soluble polar modified polymer, and water.

Claims

1. A composition comprising:

(a) at least one cellulosic gelling agent selected from the group consisting of polyquarternium-10, hydroxypropyl methylcellulose, hydroxybutyl methylcellulose, and mixtures thereof;

(b) at least one oil-soluble polar modified polymer consisting of polypropylene and/or polyethylene, modified with maleic anhydride units, and having a weight-average molecular weight of less than or equal to 25 000 g/mol and a melting point above 75°

C.; and

(c) water,

wherein the composition is in the form of an emulsion.

2. The composition of claim 1, wherein the oil-soluble polar modified polymer is present in an amount of from about 3% to about 20% by weight, based on the weight of the composition.

3. The composition of claim 1, wherein the oil-soluble polar modified polymer is present in an amount of from about 1% to about 30% by weight, based on the weight of the composition.

4. The composition of claim 1, wherein water is present in an amount of from about 5 to about 50% by weight, based on the weight of the composition.

5. The composition of claim 1, further comprising at least one non-volatile oil.

6. The composition of claim 5, wherein the non-volatile oil is present in an amount of from about 1 to about 20% by weight, based on the weight of the composition.

7. The composition of claim 1, further comprising at least one colorant.

8. The composition of claim 1, wherein the cellulosic gelling agent is present in an amount of from about 0.1% to about 10.0% by weight of the total weight of the composition.

9. The composition of claim 2, wherein the cellulosic gelling agent is present in an amount of from about 0.1% to about 10.0% by weight of the total weight of the composition.

10. The composition of claim 3, wherein the cellulosic gelling agent is present in an amount of from about 0.1% to about 10.0% by weight of the total weight of the composition.

11. The composition of claim 4, wherein the cellulosic gelling agent is present in an amount of from about 0.1% to about 10.0% by weight of the total weight of the composition.

12. The composition of claim 1, in the form of a water-in-oil emulsion.

14. The composition of claim 1, wherein the weight-average molecular weight of the oil-soluble polar modified polymer is from 1,000 to 22,000 g/mol.

15. The composition of claim 1, wherein the melting point of the oil-soluble polar modified polymer is between 90°

C. and 160°

C.

16. The composition of claim 1, wherein the oil-soluble polar modified polymer has from about 0.5% to about 10% maleic anhydride units by weight with respect to the weight of the oil soluble polar modified polymer.

17. The composition of claim 1, wherein the oil-soluble polar modified polymer has from about 1% to about 8% maleic anhydride units by weight with respect to the weight of the oil soluble polar modified polymer.

18. The composition of claim 2, wherein the oil-soluble polar modified polymer has from about 0.5% to about 10% maleic anhydride units by weight with respect to the weight of the oil soluble polar modified polymer.

19. The composition of claim 3, wherein the oil-soluble polar modified polymer has from about 1% to about 8% maleic anhydride units by weight with respect to the weight of the oil soluble polar modified polymer.

13. A method of making-up a keratinous substrate comprising applying onto the substrate in an amount sufficient to make up the substrate a composition comprising:

(a) at least one cellulosic gelling agent selected from the group consisting of polyquarternium-10, hydroxypropyl methylcellulose, hydroxybutyl methylcellulose, and mixtures thereof;

(b) at least one oil-soluble polar modified polymer consisting of polypropylene and/or polyethylene, modified with maleic anhydride units, and having a weight-average molecular weight of less than or equal to 25 000 g/mol and a melting point above 75°
