Abstract

A packaged aerosol foaming skin cleanser can include a multiphase skin cleansing composition, a low pressure foaming agent, and a package.

First claim

What is claimed is:

1. A method for cleansing skin and enhancing deposition of a benefit agent onto the skin comprising:
a. providing an aerosol foamer comprising a container body, a collapsible bag contained in the container body, a low-pressure propellant disposed between the container body and the collapsible bag, the low-pressure propellant comprising air at a pressure of 20 psi or less at 21° C., and a foamable skin cleanser disposed in the collapsible bag, the foamable skin cleanser comprising:
i. a multiphase skin cleansing composition comprising:
1. a structured surfactant phase comprising a branched structured surfactant;
2. a benefit phase comprising a hydrophobic benefit agent; wherein the multiphase cleansing composition is shear thinning and has a viscosity of about 8,000 cps to about 80,000 cps; and

ii. a low pressure foaming agent;

b. dispensing the foamable skin cleansing composition as a foam;
c. cleansing the skin with the foam and delivering the hydrophobic benefit agent to the skin.

2. The method of claim 1 , wherein the low pressure foaming agent comprises n-butane, an isobutane blend, isopentane, or a combination thereof.

3. The method of claim 1 , wherein the branched structured surfactant composition comprises sodium trideceth-2 sulfate.

4. The method of claim 1 , wherein the structured surfactant phase comprises a lamellar structure.

5. The method of claim 1 , wherein the skin cleansing composition comprises from about 5% to about 15%, by weight of the skin cleansing composition, of the hydrophobic benefit agent.

6. The method of claim 5 , wherein the hydrophobic benefit agent comprises petrolatum, soybean oil, sucrose polyester, monoglyceryl monooleate, or a combination thereof.

7. The method of claim 1 , wherein the packaged aerosol foaming skin cleanser comprises from about 4% to about 10%, by weight of the packaged aerosol foaming skin cleanser, of the low pressure foaming agent.

8. The method of claim 1 , wherein the skin cleansing composition comprises from about 7% to about 25%, by weight of the skin cleansing composition, of the branched structured surfactant.

9. The method of claim 1 , wherein the multiphase skin cleansing composition is free from humectants.

10. The method of claim 1 , wherein the multiphase skin cleansing composition is free from non-surfactant structurants.

11. The method of claim 1 , wherein the cleansing phase further comprises a non-ionic low HLB emulsifier having an HLB value of about 1.5 to about 13.

12. The method of claim 11 , wherein the non-ionic low HLB emulsifier comprises glyceryl monohydroxystearate, isosteareth-2, trideceth-3, hydroxystearic acid, propylene glycol stearate, PEG-2 stearate, sorbitan monostearate, glyceryl laurate, laureth-2, cocamide monoethanolamine, lauramide monoethanolamine, or mixtures thereof.

13. The method of claim 12 , wherein the non-ionic low HLB emulsifier comprises trideceth-3.

14. The method of claim 1 , wherein the aerosol foamer is configured as bag on valve package and the collapsible bag is attached to a valve.
