Abstract

Hair treatment composition comprising from 3 to 20% bi-or tri-carboxylic acid, from 0.1 to 10% wt. cationic surfactant and having a pH of from 1 to 2.9.

First claim

1 . Packaged hair treatment comprising from 50 to 300 ml hair treatment composition comprising from 3 to 20% bi- or tri-carboxylic acid, from 0.1 to 10% wt. cationic surfactant and having a pH of from 1 to 2.9, wherein the composition comprises a fatty material selected from fatty alcohols, fatty acids, fatty amides and mixtures thereof and wherein the cationic surfactant has the formula N + R 1 R 2 R 3 R 4 wherein R′, R 2 , R 3 and R 4 are independently (C 1 to C 30 ) alkyl or benzyl, and wherein the hair treatment composition is a single dose.

2 . Packaged hair treatment product according to claim 1 comprising from 0.1 to 15% wt. fatty material.

3 . Packaged hair treatment product according to claim 1 comprising fatty alcohol.

4 . Packaged hair treatment product according to claim 1 wherein the cationic surfactant is a mono- or di-alkyl quaternary ammonium salt comprising from 8 to 24 carbons in the alkyl chain.

5 . Packaged hair treatment product according to claim 1 wherein the carboxylic acid is selected from aconitic acid, tricarballylic acid, malonic acid, tartaric acid, citric acid and mixtures thereof.

6 . Packaged hair treatment product according to claim 1 obtainable by forming a conditioning composition comprising a cationic surfactant and a fatty material and adding a solution of citric acid which has been buffered to a pH of from 1 to 2.8.

7 . Packaged hair treatment product according to claim 6 wherein the conditioning composition is formed by heating cationic surfactant in water and then adding fatty material at a temperature greater than the melting temperature of the fatty material and then adding a solution of citric acid buffered to a pH of from 1.0 to 2.9.

8 . Packaged hair treatment product according to claim 1 comprising from 100 to 200 ml hair treatment composition.

9 . A method for styling hair comprising:
applying to hair a hair treatment composition comprising from 3 to 20% bi- or tri-carboxylic acid, from 0.1 to 10% wt. cationic surfactant and having a pH of from 1 to 2.9, wherein the composition comprises a fatty material selected from fatty alcohols, fatty acids, fatty amides and mixtures thereof and wherein the cationic surfactant has the formula N 30 R 1 R 2 R 3 R 4 wherein R 1 , R 2 , R 3 and R 4 are independently (C 1 to C 30 ) alkyl or benzyl. leaving the composition on the hair for from 5 to 90 minutes; rinsing the product from the hair; and styling
wherein the treatment is applied to dry hair.

10 . Method according to claim 9 of durably styling the hair by applying to the hair a hair treatment composition according to claim 1 .
