Abstract

Claims (42)

1. A hair care composition comprising:

a) one or more anionic surfactants, wherein the one or more anionic surfactants include from about 8% to about 25% of sodium deceth-n sulfate where n is between 0.5 to 3.5; or from about 8% to 13% by weight of one or more amino acid based anionic surfactant;

b) from about 0.01% to 10% of one or more surfactant-soluble agent wherein the surfactant-soluble agent is piroctone olamine;

c) wherein the composition has a fractional soluble agent concentration (a) of 0.5-1.0 wherein ‘a’ is defined as

a

where C is the surfactant-soluble agent concentration, C s i are the surfactant concentrations and K s i is the solubilization capacity of each type of surfactant wherein K s i can be measured for any surfactant and surfactant-soluble agent combination and wherein a surfactant to surfactant-soluble agent concentration is 15:1 by weight, wherein the composition has a deposition efficiency of greater than or equal to 1.2x that of a deposition control composition.

2. A hair care composition according to claim 1 wherein the composition has a deposition efficiency of greater than or equal to 1.4x that of a deposition control composition.

3. A hair care composition according to claim 1 wherein the composition has a deposition efficiency of greater than or equal to 1.6x that of a deposition control composition.

4. A hair care composition according to claim 1 wherein the fractional soluble agent concentration is from about 0.6 to 1.0.

5. A hair care composition according to claim 1 wherein the fractional soluble agent concentration is from about 0.75 to 1.

6. A hair care composition according to claim 1 wherein the surfactant-soluble agent is from about 0.2% to 3% by weight.

7. A hair care composition according to claim 1 wherein the surfactant-soluble agent is from about 0.3% to 1% by weight.

8. A hair care composition according to claim 1 further comprising one or more scalp health agents.

9. A hair care composition according to claim 1 further comprising the surfactant-soluble agent azole.

10. A hair care composition according to claim 9 further comprising wherein the azole is climbazole.

11. A hair care composition according to claim 1 further comprising the surfacant-soluble agent menthol.

12. A hair care composition comprising:

a combination of anionic surfactants including from about 8% to about 25% of sodium deceth-n sulfate where n is between 0.5 to 3.5 and from about 8% to 13% by weight an amino acid based anionic surfactants;

b) from about 0.01% to 10% of one or more surfactant-soluble agent wherein the surfactant-soluble agent is piroctone olamine;

c) wherein the composition has a fractional soluble agent concentration (a) of 0.5-1.0 wherein ‘a’ is defined as
