Abstract

A cosmetic composition comprising a thickening polymer having hydrophobic and hydrophilic portions, a non-ionic surfactant, a neutralising agent, a non-ionic kosmotrope and water. Also, a hair colorant formulation obtained from mixing said composition and a hair dye. Also, the use of said formulation for colouring and/or sculpting hair.

First claim

What is claimed is:

1 . A cosmetic composition comprising:
at least about 12% thickening polymer having hydrophobic and hydrophilic portions; a non-ionic surfactant; a neutralising agent; a non-ionic kosmotrope; water; and wherein the ratio of thickening polymer having hydrophobic and hydrophilic portions to neutralising agent is from about 10:1 to about 60:1.

2 . The composition of claim 1 , wherein the thickening polymer is an associative thickening polymer.

3 . The composition of claim 2 , wherein the thickening polymer is acrylate-based.

4 . The composition of claim 1 , wherein the composition comprises from about 15 to about 25% thickening polymer;

5 . The composition of claim 4 , wherein the composition also comprises from about 5% to about 20% non-ionic kosmotrope.

6 . The composition of claim 1 , wherein the thickening polymer is selected from the group consisting of Acrylates/Ceteth-20 Itaconate Copolymers, Polyurethane-39 polymers, and mixtures thereof.

7 . The composition of claim 6 , wherein the thickening polymer is an Acrylates/Ceteth-20 Itaconate Copolymer.

8 . The composition of claim 1 , wherein the non-ionic kosmotrope is selected from the group consisting of polyethylene glycol, ethylene glycol, propylene glycol, propane-1,2,3-triol, and mixtures thereof

9 . The composition of claim 8 , wherein the non-ionic kosmotrope is propane-1,2,3-triol.

10 . The composition of claim 1 , wherein the composition is substantially free of any further thickening polymer, or is substantially free of any film-forming polymer or hair fixing polymer except for the thickening polymer having hydrophobic and hydrophilic portions.

11 . The composition of claim 1 , wherein the neutralising agent is selected from the group consisting of: aminomethyl propanol, ethanolamine, and mixtures thereof.

12 . The composition of claim 11 , wherein the neutralising agent is aminomethyl propanol.

13 . The composition of claim 12 , wherein the composition comprises from about 0.01% to about 2% neutralising agent.

14 . The composition of claim 13 , wherein the composition comprises from about 0.2% to about 0.8% neutralising agent.

15 . The composition of claim 14 , wherein the ratio of thickening polymer having hydrophobic and hydrophilic portions to neutralising agent is from about 20:1 to about 50:1.

16 . The composition according to claim 1 , wherein the composition comprises at least one preservative; and wherein the preservative is selected from the group consisting of benzyl alcohol, phenoxyethanol, and mixtures thereof.

17 . The composition according to claim 1 , wherein the composition consists of:
from about 15 to about 25% thickening polymer having hydrophobic and hydrophilic portions; a non-ionic surfactant; a neutralising agent; a non-ionic kosmotrope; water. and wherein the ratio of thickening polymer having hydrophobic and hydrophilic portions to neutralising agent is from about 10:1 to about 60:1.

18 . A hair colorant formulation obtained from mixing:
the composition according to claim 1 ; a hair dye.

19 . A method of colouring hair comprising applying the hair colorant formulation according to claim 18 to human hair.

20 . The method of claim 19 comprising sculpting hair.
