Abstract

A packaged aerosol foaming skin cleanser can include a multiphase skin cleansing composition; a foaming agent including a hydrofluoroolefin, a hydrochlorofluoroolefin, or a combination thereof; and a package.

First claim

What is claimed is:

1. A packaged aerosol foaming skin cleanser, comprising:
a) a multiphase skin cleansing composition, comprising a structured cleansing phase and a benefit phase, wherein the structured cleansing phase comprises a branched anionic surfactant, and the benefit phase comprises a first hydrophobic benefit agent selected from the group consisting of petrolatum, glycerides, butylated hydroxytoluene, sucrose polyesters, lanolin, lanolin derivatives, lanolin esters, lanolin oil, natural waxes, synthetic waxes; wherein the multiphase cleansing composition is shear thinning; wherein the multiphase composition is a dispersion;
b) a foaming agent comprising a hydrofluoroolefin, a hydrochlorofluoroolefin, or a combination thereof; and
c) a package for dispensing the aerosol foaming skin cleanser.

2. The packaged aerosol foaming skin cleanser of claim 1 , wherein the package comprises a bag in bottle package including a container body with an exterior wall, wherein within the container body is a collapsible bag.

3. The packaged aerosol foaming skin cleanser of claim 2 , wherein the bag in bottle package is a bag on valve package.

4. The packaged aerosol foaming skin cleanser of claim 3 , wherein the package further comprises a valve, wherein the collapsible bag is attached to the valve and resides within the container body.

5. The packaged aerosol foaming skin cleanser of claim 4 , wherein the aerosol foaming skin cleanser further comprises a propellant in between the exterior wall and the collapsible bag comprising n-butane, an isobutane blend, isopentane, compressed air, or a combination thereof.

6. The packaged aerosol foaming skin cleanser of claim 5 , wherein the propellant is a combination of isobutane and isopentane with about 25 weight percent of the isobutane and about 75 weight percent of the isopentane.

7. The packaged aerosol foaming skin cleanser of claim 5 , wherein the propellant is filled to a pressure of about 12-15 psi.

8. The packaged aerosol foaming skin cleanser of claim 1 , wherein the package is a dip tube package.

9. The packaged aerosol foaming skin cleanser of claim 1 , wherein the multiphase skin cleansing composition is free from non-surfactant structurants.

10. The packaged aerosol foaming skin cleanser of claim 1 , wherein the skin cleansing composition comprises from about 5% to about 30%, by weight of the skin cleansing composition, of the branched anionic surfactant.

11. The packaged aerosol foaming skin cleanser of claim 10 , wherein the branched anionic surfactant comprises sodium trideceth-2 sulfate.

12. The packaged aerosol foaming skin cleanser of claim 11 , wherein the skin cleansing composition comprises from about 3% to about 20%, by weight of the skin cleansing composition, of the hydrophobic benefit agent.

13. The packaged aerosol foaming skin cleanser of claim 12 , wherein the benefit agent further comprises a second hydrophobic benefit agent and wherein the second hydrophobic benefit agent consists of monoglyceryl monooleate.

14. The packaged aerosol foaming skin cleanser of claim 12 , wherein the packaged aerosol foaming skin cleanser comprises from about 3% to about 15%, by weight of the aerosol foaming skin cleanser, of the foaming agent.

15. The packaged aerosol foaming skin cleanser of claim 14 , wherein the skin cleansing composition further comprises a non-ionic low HLB emulsifier with an HLB of about 1.5 to about 13.

16. The packaged aerosol foaming skin cleanser of claim 15 , 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 a mixture thereof.

17. The packaged aerosol foaming skin cleanser of claim 15 , wherein the non-ionic low HLB emulsifier comprises trideceth-3.

18. The packaged aerosol foaming skin cleanser of claim 4 , wherein the foaming agent comprises trans-1,3,3,3-tetrafluoropropene.
