Abstract

A hair care composition is disclosed comprising a polyhydroxy fatty acid amide surfactant of general formula (I) wherein R 1 is a C 1 -C 4 alkyl groups or hydroxy-substituted C 1 -C 4 alkyl groups; R 2 CO is a linear or branched, saturated or unsaturated C 12 -C 18 acyl group, a silicone compound, and from 0.01 to 10% by weight of an anti-dandruff agent selected from piroctone olamine, azole based anti-fungal agents and mixtures thereof.

Claims (20)

1 . A hair care composition comprising:

(a) from 5 to 20% by weight of a polyhydroxy fatty acid amide surfactant wherein the polyhydroxy fatty acid amide surfactant is a combination of lauroyl methyl glucamide, and myristoyl methyl glucamide;

(b) from 1 to 3% by weight of a silicone compound wherein the silicone compound is dimethicone, dimethiconol, or a combination thereof; and

(c) from 0.05 to 1.5% by weight of piroctone olamine.

2 . The hair care composition according to claim 1 , wherein a weight ratio of the lauroyl methyl glucamide and the myristoyl methyl glucamide is from 1:5 to 10:1.

3 . The hair care composition according to claim 2 , wherein the weight ratio of the lauroyl methyl glucamide and the myristoyl methyl glucamide is from 1:2 to 5:1.

4 . The hair care composition according to claim 1 , wherein the silicone compound comprises a mixture of dimethicone and dimethiconol.

5 . The hair care composition according to claim 1 , wherein the composition further comprises a cationic polymer.

6 . The hair care composition according to claim 1 , wherein the cationic polymer comprises cationic cellulose derivatives, cationic guar gum derivatives, or mixtures thereof.

7 . A method of depositing anti-dandruff agents onto scalp comprising the step of applying the hair care composition according to claim 1 onto scalp surfaces of an individual followed by rinsing the surfaces with water.

8 . The hair care composition according to claim 1 further comprising at least one preservative.

9 . The hair care composition according to claim 1 further comprising at least one suspending agent.

10 . The hair care composition according to claim 1 further comprising at least one amphoteric surfactant.

11 . The hair care composition according to claim 1 further comprising at least one zwitterionic surfactant.

12 . The hair care composition according to claim 1 further comprising at least one anionic surfactant.

13 . The hair composition according to claim 1 , wherein the composition has a pH from 4 to 7.

14 . A hair care composition comprising:

(a) from 5 to 20% by weight of a polyhydroxy fatty acid amide surfactant wherein the polyhydroxy fatty acid amide surfactant is a combination of lauroyl methyl glucamide, and myristoyl methyl glucamide;

(b) from 1 to 3% by weight of a silicone compound wherein the silicone compound is a combination of dimethicone and dimethiconol; and

(c) from 0.05 to 1.5% by weight of piroctone olamine.
