Cosmetic Composition Comprising a Thickening Polymer
A cosmetic composition comprising a thickening polymer, a non-ionic surfactant, 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.
1 . A cosmetic composition comprising:
from about 1% to about 5% thickening polymer being (a) crosslinked and having a hydrophobic portion, or (b) a polysaccharide;
a non-ionic surfactant;
from about 5% to about 20% non-ionic kosmotrope;
water.
2 . The composition of claim 1 , wherein the thickening polymer is an Acrylates/C10-30 Alkyl Acrylate Crosspolymer.
3 . The composition of claim 1 , wherein the composition further comprises a neutralising agent, and wherein the neutralising agent is selected from the group consisting of aminomethyl propanol, ethanolamine, and mixtures thereof.
4 . The composition of claim 3 , wherein the neutralising agent is aminomethyl propanol.
5 . The composition of claim 1 , wherein the non-ionic surfactant is a castor oil having polyethylene glycol ether groups or polypropylene glycol ether groups.
6 . 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.
7 . The composition of claim 6 , wherein the non-ionic kosmotrope is propane-1,2,3-triol.
8 . The composition of claim 1 , wherein the composition is substantially free of any further polymer, or is substantially free of any film-forming polymer or hair fixing polymer except for the thickening polymer.
9 . The composition of claim 1 , wherein the composition comprises from about 1% to about 5% thickening polymer being a polysaccharide.
10 . The composition of claim 3 , wherein the composition comprises from about 0.01% to about 2% neutralising agent.
11 . The composition of claim 3 , wherein the composition comprises from about 0.2% to about 0.8% neutralising agent.

13 . The composition of claim 12 , wherein the composition comprises from about 65% to about 75% water.
14 . The composition of 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.
15 . The composition of claim 14 , wherein the preservative is a mixture of benzyl alcohol and phenoxyethanol.
16 . The composition of claim 1 , wherein the thickening polymer has an average degree of crosslinking (crosslinks per unit) of at least about 0.02.
17 . The composition of claim 1 , wherein the composition consists of:
from about 1% to about 2% thickening polymer being crosslinked and having a hydrophobic portion;
a non-ionic surfactant;
a neutralising agent;
from about 5% to about 20% non-ionic kosmotrope;
water.
