Abstract

The present invention is directed to emulsion composition, in solid form, capable of imparting shine, hydration and/or moisturization onto lips containing: a) at least one polyamine; (b) at least one oil-soluble high carbon polar modified polymer; (c) water; (d) at least one non-volatile solvent; (e) at least one wax having a high melting point; and (e) optionally, at least one colorant.

Claims

1. An emulsion lipstick composition, in solid form, comprising:

(a) at least one polyamine;

(b) at least one oil-soluble high carbon polar modified polymer;

(c) water;

(d) at least one non-volatile solvent capable of solubilizing the oil-soluble high carbon polar modified polymer; and

(e) at least on high melting point wax.

2. The composition of claim 1, wherein the at least one polyamine is a branched polyethyleneimine.

3. The composition of claim 1, wherein the composition is made using from 0.05 to 5% by weight, based on the weight of the composition, of the polyamine.

4. The composition of claim 1, wherein the composition is made using from 3 to 20% by weight, based on the weight of the composition, of the oil-soluble high carbon polar modified polymer.

5. The composition of claim 1, wherein water is present in an amount of from 0.1 to 50% by weight, based on the weight of the composition.

6. The composition of claim 1, wherein the non-volatile solvent is a non-volatile oil.

7. The composition of claim 1, wherein the non-volatile solvent is present in an amount of from 20 to 90% by weight, based on the weight of the composition.

8. The composition of claim 1, wherein the wax is present in an amount of from 5 to 20% by weight, based on the weight of the composition.

9. The composition of claim, 1 wherein the composition has a hardness value of from about 50 to about 200 gram-force.

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

11. The composition of claim 1, wherein the composition is free of emulsifiers and/or silicone fluids.

12. A method of imparting shine, hydration and/or moisturization onto lips comprising applying onto the lips a the composition of claim 1.

13. An emulsion lipstick composition, in solid form, comprising:

(a) a reaction product of at least one polyamine and at least one oil-soluble high carbon polar modified polymer;

(b) water;

(c) at least one non-volatile solvent capable of solubilizing the oil-soluble high carbon polar modified polymer; and

(d) at least on high melting point wax.

14. The composition of claim 13, wherein the at least one polyamine is a branched polyethyleneimine.

15. The composition of claim 13, wherein the composition is made using from 0.05 to 5% by weight, based on the weight of the composition, of the polyamine.

16. The composition of claim 13, wherein the composition is made using from 3 to 20% by weight, based on the weight of the composition, of the oil-soluble high carbon polar modified polymer.

17. The composition of claim 13, wherein water is present in an amount of from 0.1 to 50% by weight, based on the weight of the composition.
