Abstract

The present invention generally relates to emulsions including a water-in-oil emulsion containing an oil-soluble polar modified polymer and polylysine.

Claims

1. An emulsion comprising a water-in-oil emulsion comprising:

(a) water;

(b) at least one polylysine; and

(c) at least one polar modified polymer selected from the group consisting of;

(1) a low carbon oil-soluble polar modified polymer comprising at least one C2-C4 monomer and modified with at least one hydrophilic unit, and having a weight-average molecular weight of less than or equal to 25 000 g/mol and a melting point above 75°

C.;

(2) an high carbon oil-soluble polar modified polymer comprising at least one C22-C40 monomer and modified with at least one hydrophilic unit, and having a weight-average molecular weight of less than or equal to 30000 g/mol and a crystallinity of 8% to 60%; and

(3) mixtures thereof.

2. The emulsion of claim 1, wherein the emulsion comprises at least one low carbon oil-soluble polar modified polymer comprising at least one C2-C4 monomer and modified with at least one hydrophilic unit, and having a weight-average molecular weight of less than or equal to 25 000 g/mol and a melting point above 75°

C.

3. The emulsion of claim 2, wherein the at least one low carbon oil-soluble polar modified polymer consists essentially of polypropylene and maleic anhydride units.

4. The emulsion of claim 1, wherein the composition comprises at least one oil-soluble high carbon polar modified polymer comprising at least one C26-C28 monomer and modified with at least one hydrophilic unit, and having a weight-average molecular weight of less than or equal to 30000 g/mol and a crystallinity of 8% to 60%.

5. The emulsion of claim 4, wherein the at least one high carbon oil-soluble polar modified polymer consists essentially of C26-C28 alpha olefin and maleic acid anhydride units.

6. The emulsion of claim 1, further comprising at least one coloring agent.

7. The emulsion of claim 1, wherein the emulsion is made using from 0.01 to 10% by weight, based on the weight of the emulsion, of the polylysine.

8. The emulsion of claim 1, wherein the emulsion is made using from 0.05 to 8% by weight, based on the weight of the emulsion, of the polylysine.

9. The emulsion of claim 1, wherein the emulsion is made using from 0.5 to 30% by weight, based on the weight of the emulsion, of the oil-soluble polar modified polymer.

10. The emulsion of claim 1, wherein water is present in an amount of from 45 to 90% by weight, based on the weight of the emulsion.

11. The emulsion of claim 1, further comprising at least one surfactant.

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

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

14. A cosmetic composition comprising the emulsion of claim 1.

15. A method of making up skin comprising applying the composition of claim 11 to the skin.

16. A method of making up lips comprising applying the composition of claim 11 to the lips.

17. A method of making up eyelashes comprising applying the composition of claim 11 to the eyelashes.
