Abstract

An emulsion lip composition, in solid or stick form, comprising: (a) a reaction product of (i) at least one polyamine with (ii) an oil-soluble polar modified polymer comprising at least one C2-C20 monomer; (b) water; (c) at least one non-volatile solvent; and (d) at least one colorant; and a method of using thereof.

Claims

1. An emulsion lip composition, in solid or stick form, comprising:

(a) a reaction product of (i) at least one polyamine with (ii) an oil-soluble polar modified polymer comprising at least one C2-C20 monomer;

(b) water;

(c) at least one non-volatile solvent; and

(d) at least one colorant.

2. The composition of claim 1, wherein the composition is free of silicone resin, surfactant and/or emulsifier.

3. The composition of claim 1, wherein the composition further comprises at least one wax, at least one water soluble film forming polymer and at least one volatile oil.

4. The composition of claim 1, wherein the polyamine is branched polyethyleneimine.

5. The composition 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.

6. The composition of claim 1, wherein the composition is made using from 3 to 30% by weight, based on the weight of the composition, of the polar modified polymer.

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

8. The composition of claim 3, wherein the composition is made using from 3 to 30% by weight, based on the weight of the composition, of the polar modified polymer.

9. 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.

10. The composition of claim 3, wherein water is present in an amount of from 0.1 to 50% by weight, based on the weight of the composition.

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

12. The composition of claim 3, wherein the water soluble film forming polymer is selected from the group consisting of polyvinyl pyrolidone, polyvinyl alcohol, and mixtures thereof.

13. The composition of claim 3, wherein the water soluble film forming polymer is present in an amount of from 1 to 15% by weight, based on the weight of the composition.
