Abstract

The compositions of the present invention relate to improved shampoo compositions having from about from about 5 to about 50 weight percent of a detersive surfactant, at least about 0.1 weight percent of anti-dandruff particles, at least about 0.05 weight percent of a cationic polysaccharide polymer having a molecular weight of from about 10,000 to about 10,000,000 and a charge density from about 1.4 meq/gm to about 7.0 meq/gm, and at least about 20.0 weight percent of an aqueous carrier.

Claims

1. A shampoo composition comprising:

a) from about 5 to about 50 weight percent of a detersive surfactant,

b) at least about 0.1 weight percent of anti-dandruff particles,

c) at least about 0.05 weight percent of a cationic polysaccharide polymer having a molecular weight of from about 10,000 to about 10,000,000 and a charge density from about 1.4 meq/gm to about 7.0 meq/gm, and

d) at least about 20.0 weight percent of an aqueous carrier.

2. A shampoo composition according to claim 1, wherein said cationic polysaccharide polymer conforms to the general formula:

3. The composition of claim 1 wherein said cationic polysaccharide polymer has a charge density of from about 1.7 meq/gm to about 7 meq/gm.

4. The composition of claim 1 wherein said cationic polysaccharide polymer has a charge density of from about 1.9 meq/gm to about 5 meq/gm.

5. The composition of claim 1 wherein said anti-dandruff particles comprise a zinc salt of 1-hydroxy-2-pyridinethione.

6. The composition of claim 4 wherein said anti-dandruff particles comprise a zinc salt of 1-hydroxy-2-pyridinethione.

7. The composition of claim 1 wherein the weight ratio of said cationic polysaccharide polymer to said anti-dandruff particles is from about 1:

1 to about 1;

20.

8. A method of treating hair by administering a safe and effective amount of the composition according to claim 1.
