Abstract

The invention relates to a cosmetic composition comprising at least one polar modified polymer and at least one tackifier, as well as to methods of using such compositions.

Claims

1. A composition comprising at least one polar modified polymer and at least one tackifier.

2. The composition of claim 1, wherein the composition is an emulsion.

3. The composition of claim 1, further comprising at least one coloring agent.

4. The composition of claim 1, wherein the at least one polar modified polymer is selected from the group consisting of a wax consisting essentially of polypropylene and maleic anhydride units, a wax consisting essentially of C26-C28 alpha olefin and maleic acid anhydride units, and mixtures thereof.

5. The composition of claim 1, wherein the at least one polar modified polymer is a wax consisting essentially of polypropylene and maleic anhydride units.

6. The composition of claim 1, wherein the at least one polar modified polymer is a wax consisting essentially of C26-C28 alpha olefin and maleic acid anhydride units.

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

8. The composition of claim 7, wherein the at least one block copolymer is an A-B polymer or an A-B-A polymer, where A represents a hard segment and B represents a soft segment.

9. The composition of claim 8, wherein the polymer comprises polystyrene.

10. The composition of claim 1, further comprising an alkyl silsesquioxane resin.

11. The composition of claim 7, further comprising an alkyl silsesquioxane resin.

12. A method of making up eyelashes comprising applying the composition of claim 1 to the eyelashes.

13. A method of making up lips comprising applying the composition of claim 1 to the lips.

14. A method of making up eyelashes comprising applying the composition of claim 7 to the eyelashes.

15. A method of making up lips comprising applying the composition of claim 7 to the lips.
