Abstract

Claims (29)

1. A hair care composition comprising:

a) an anti-dandruff agent selected from piroctone olamine, selenium sulfide, and mixtures thereof; and

b) a copolymer wherein the copolymer is acrylamidopropyltrimonium chloride/acrylamide copolymer;

wherein the weight ratio of the amount of the copolymer to the amount of the anti-dandruff agent is in the range of from 1:5 to 1:1.

2. The hair care composition according to claim 1 , wherein the composition comprises the anti-dandruff agent in an amount of from 0.01 to 10% by weight of the composition.

3. The hair care composition according to claim 2 , wherein the composition comprises the anti-dandruff agent in an amount of from 0.01 to 5% by weight of the composition.

4. The hair care composition according to claim 1 , wherein the weight ratio of the amount of the copolymer to the amount of the anti-dandruff agent is in the range of from 1:4 to 1:1.

5. The hair care composition according to claim 4 , wherein the weight ratio of the amount of the copolymer to the amount of the anti-dandruff agent is in the range of from 1:4 to 1:1.5.

6. The hair care composition according to claim 1 , wherein the composition comprises a cleansing surfactant.

8. The hair composition according to claim 1 , wherein the composition comprises a conditioning agent.

9. The hair composition according to claim 8 , wherein the conditioning agent is a silicone oil.

10. The hair composition according to claim 9 , wherein the conditioning agent is selected from dimethicone, dimethiconol, or a mixture thereof.

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

12. The hair care composition according to claim 11 , wherein the cationic polymer is cationic cellulose, cationic guar, or mixtures thereof.

13. The hair care composition according to claim 12 , wherein the cationic guar is guar hydroxypropyltrimonium chloride.

14. The hair care composition according to claim 1 , wherein the composition is a shampoo.

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