Aerosol Foam Skin Cleanser

Abstract

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

What is claimed is: 
     
         1 . A packaged aerosol foaming skin cleanser, comprising:
 a) a multiphase skin cleansing composition, comprising a structured surfactant phase and a benefit phase, wherein the structured surfactant phase comprises a branched structured surfactant, and the benefit phase comprises 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;   b) a low pressure foaming agent; and   c) a package.   
     
     
         2 . The packaged aerosol foaming skin cleanser of  claim 1 , wherein the low pressure foaming agent comprises n-butane, an isobutane blend, isopentane, or a combination thereof. 
     
     
         3 . The packaged aerosol foaming skin cleanser of  claim 2 , wherein the package is a dip tube package. 
     
     
         4 . The packaged aerosol foaming skin cleanser of  claim 2 , wherein the package is a bag on valve package. 
     
     
         5 . The packaged aerosol foaming skin cleanser of  claim 4 , wherein the bag on valve package comprises a collapsible bag attached to a valve, wherein the multiphase skin cleansing composition is within the collapsible bag. 
     
     
         6 . The packaged aerosol foaming skin cleanser of  claim 5 , wherein the bag on valve package further comprises an exterior wall at least partially surrounding the collapsible bag and a propellant between the exterior wall and the collapsible bag. 
     
     
         7 . The packaged aerosol foaming skin cleanser of  claim 6 , wherein the propellant comprises n-butane, an isobutane blend, isopentane, compressed air, or a combination thereof. 
     
     
         8 . The packaged aerosol foaming skin cleanser of  claim 7 , wherein the propellant is filled to a pressure of about 12 psi to about 15 psi. 
     
     
         9 . The packaged aerosol foaming skin cleanser of  claim 1 , wherein the low pressure foaming agent is a combination of isobutane and isopentane with about 25 weight percent of the isobutane and about 75 weight percent of the isopentane. 
     
     
         10 . The packaged aerosol foaming skin cleanser of  claim 1 , wherein the multiphase skin cleansing composition is free from non-surfactant structurants. 
     
     
         11 . The packaged aerosol foaming skin cleanser of  claim 1 , wherein the multiphase skin cleansing composition is free from humectants. 
     
     
         12 . The packaged aerosol foaming skin cleanser 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. 
     
     
         13 . The packaged aerosol foaming skin cleanser of  claim 12 , wherein the branched structured surfactant composition comprises sodium trideceth-2 sulfate. 
     
     
         14 . The packaged aerosol foaming skin cleanser 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. 
     
     
         15 . The packaged aerosol foaming skin cleanser of  claim 14 , wherein the hydrophobic benefit agent comprises petrolatum, soy bean oil, sucrose polyester, monoglyceryl monooleate, or a combination thereof. 
     
     
         16 . The packaged aerosol foaming skin cleanser of  claim 1 , wherein the packaged aerosol foaming skin cleanser comprises from about 4% to about 10%, by weight of the aerosol foaming skin cleanser, of the low pressure foaming agent. 
     
     
         17 . The packaged aerosol foaming skin cleanser of  claim 1 , wherein the skin cleansing composition further comprises a non-ionic low HLB emulsifier. 
     
     
         18 . The packaged aerosol foaming skin cleanser of  claim 17 , 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. 
     
     
         19 . The packaged aerosol foaming skin cleanser of  claim 17 , wherein the non-ionic low HLB emulsifier comprises trideceth-3.
