Abstract

A non-aqueous, non-aerosol foamable composition is provided that includes at least 40 wt % alcohol, based upon the total weight of the alcoholic composition; a foaming surfactant; and a skin benefit agent selected from the group consisting of emollients, humectants, occlusive agents, and other moisturizers to provide moisturization, skin softening, skin barrier maintenance, anti-irritation, or other skin health benefits. The foamable alcoholic composition forms a stable foam when mixed with air.

Claims

1. A non-aqueous, non-aerosol foamable composition comprising:

at least 40 wt % alcohol, based upon the total weight of the alcoholic composition;

from about 0.02 to about 4 wt. % of a foaming surfactant;

from about 0.1 to about 50 wt. % of a complex of hydrogen peroxide and a polymer formed from at least one vinyl heterocyclic monomer; and

a skin benefit agent selected from the group consisting of emollients, humectants, occlusive agents, and other moisturizer to provide moisturization, skin softening, skin barrier maintenance, anti-irritation, or other skin health benefits,

wherein the composition comprises from 0 to about 1 wt. % water, based upon the total weight of the composition.

2. The composition of claim 1, wherein said skin benefit agent is selected from the group consisting of glycols, glycerols, oils, esters, silicones, and ethers.

3. The composition of claim 2, wherein said skin benefit agent is selected from the group consisting of propylene glycol and ethylene glycol.

4. The composition of claim 1, where said composition comprises less than about 0.5 wt. % water, based upon the total weight of the composition.

5. The composition of claim 4, where said composition comprises less than about 0.1 wt. % water, based upon the total weight of the composition.

6. The composition of claim 1, where said composition is devoid of water.

7. The composition of claim 1, where the foaming surfactant is a siloxane polymer surfactant.

8. The composition of claim 7, where the skin benefit agent is propylene glycol or ethylene glycol.

9. The composition of claim 8, where the complex of hydrogen peroxide and a polymer formed from at least one vinyl heterocyclic monomer is a complex of hydrogen peroxide and polyvinylpyrrolidone.

10. The composition of claim 7, wherein the composition further comprises one or more foam enhancers.

11. A non-aqueous, non-aerosol foamable composition comprising:

at least 40 wt % alcohol, based upon the total weight of the alcoholic composition;

from about 0.02 to about 4 wt. % of a foaming surfactant;

from about 0.1 to about 50 wt. % of a complex of hydrogen peroxide and a polymer formed from at least one vinyl heterocyclic monomer; and

a skin benefit agent selected from the group consisting of emollients, humectants, occlusive agents, and other moisturizer to provide moisturization, skin softening, skin barrier maintenance, anti-irritation, or other skin health benefits,

wherein the composition comprises from 0 to about 1 wt. % water, based upon the total weight of the composition, and wherein the composition, upon being mixed with air, forms a foam that is stable for at least about 3 minutes at room temperature.

12. A method for forming a stabilized alcoholic foam, the method comprising the steps of:

combining a C_1-6 alcohol, a foaming surfactant, a non-aqueous skin benefit agent, a complex of hydrogen peroxide and a polymer formed from at least one vinyl heterocyclic monomer, and zero or less than 0.5 wt. % of added water, to form a foamable alcoholic composition;

mixing said alcoholic composition and air or an inert gas in a mixing chamber to form a mixture; and

passing said mixture through a mesh screen to form a foam, wherein said foamable alcoholic composition comprises at least about 40 percent by weight alcohol, based upon the total weight of the alcoholic composition, and wherein the the foam stability of the stabilized foam at room temperature is at least about 30 seconds.

13. The method of claim 12, wherein the foamable complsition comprises at least 40 wt % alcohol, based upon the total weight of the alcoholic composition;

from about 0.02 to about 4 wt. % of a foaming surfactant selected from the group consisting of anionic, cationic, and zwitterionic fluorosurfactants, and combinations thereof;

from about 0.1 to about 50 wt. % of a complex of hydrogen peroxide and a polymer formed from at least one vinyl heterocyclic monomer; and

a skin benefit agent selected from the group consisting of emollients, humectants, occlusive agents, and other moisturizer to provide moisturization, skin softening, skin barrier maintenance, anti-irritation, or other skin health benefits, wherein the composition comprises from 0 to about 1 wt. % water, based upon the total weight of the composition.
