Methods of cosmetically treating skin conditions with a cosmetic personal cleansing composition
A method of treating a skin condition including applying a rinse-off multi-phase cleansing composition including a cleansing phase including an anionic surfactant and zinc pyrithione and a benefit phase including a benefit agent.
1. A method of treating atopic dermatitis, comprising applying to at least a portion of the skin of an individual with atopic dermatitis a rinse-off multi-phase cleansing composition comprising a cleansing phase comprising an anionic surfactant and zinc pyrithione and a benefit phase comprising a benefit agent.
2. The method of claim 1 , further comprising rinsing the multi-phase cleansing composition from the skin of the individual.
3. The method of claim 1 , wherein the benefit agent comprises petrolatum, glyceryl monooleate, or a combination thereof.
4. The method of claim 3 , wherein the benefit agent comprises a combination of petrolatum and glyceryl monooleate and the ratio of petrolatum to glyceryl monooleate is about 98:2, by weight of the benefit phase.
5. The method of claim 1 , wherein the cleansing composition is applied once per day for 5 days or more.
6. The method of claim 1 , wherein the composition comprises from about from about 0.25% to about 1.0%, by weight of the composition, of the zinc pyrithione.
7. The method of claim 1 , wherein the anionic surfactant comprises sodium trideceth(n) sulfate, wherein n is from about 0.5 to about 2.7.
8. The method of claim 1 , wherein the cleansing phase further comprises from about 0.2% to about 0.8%, by weight of the composition, of a cationic deposition polymer.
9. The method of claim 8 , wherein the cationic deposition polymer comprises guar hydroxypropyltrimonium chloride.
10. The method of claim 9 , wherein the cationic polymer comprises a cationic charge density of from about 1.0 meq/g to about 1.5 meq/g.
11. A method of treating atopic dermatitis, comprising applying a multi-phase cleansing composition to at least a portion of skin of an individual with atopic dermatitis, wherein the composition comprises a structured cleansing phase comprising from about 3% to about 20%, by weight of the composition, of sodium trideceth(n) sulfate, wherein n is about 2.0, and from about 0.25% to about 5.0%, by weight of the composition, of zinc pyrithione; and from about 1% to about 30%, by weight of the composition, of a benefit phase, comprising from about 1% to about 3% by weight of the composition, of glyceryl monooleate, and from about 5% to about 15%, by weight of the composition, of petrolatum.
12. The method of claim 11 , further comprising rinsing the multi-phase cleansing composition from the skin of the individual.
13. The method of claim 12 , wherein the ratio of petrolatum to monoglyceryl monooleate is about 98:2, by weight of the benefit phase.
14. The method of claim 13 , wherein the cleansing phase further comprises from about 0.2% to about 0.8%, by weight of the composition, of a cationic deposition polymer.
15. The method of claim 14 , wherein the cationic polymer comprises a cationic charge density of about 1.0 meq/g to about 1.5 meq/g.
16. The method of claim 15 , wherein the composition further comprises from about 0.5% to about 2.5%, by weight of the composition, of a nonionic emulsifier.
17. The method of claim 16 , wherein the cationic deposition polymer comprises guar hydroxypropyltrimonium chloride.
18. The method of claim 17 , wherein the composition comprises from about 0.25% to about 1.0%, by weight of the composition, of the zinc pyrithione.
