Abstract

Claims (21)

1. A foamable composition comprising:

at least 60 weight percent of a C 1-4 alcohol;

from about 0.1 to about 20 weight percent of a gemini surfactant; and

from about 0.1 to about 20 weight percent of a di-ester surfactant, wherein all weight percentages are based upon the total weight of the composition,

wherein said gemini surfactant is disodium ethylene dicocamide PEG-15 disulfate,

wherein said di-ester surfactant is selected from sodium sodium stearoyl lactylate, sodium behenoyl lactylate, sodium oleoyl lactylate, sodium cocoyl lactylate, sodium caproyl lactylate, lauroyl lactylic acid, myristoyl lactylic acid, triethanolamine stearoyl lactylate, triethanolamine behenoyl lactylate, triethanolamine oleoyl lactylate, triethanolamine cocoyl lactylate, triethanolamine caproyl lactylate, diethanolamine stearoyl lactylate, diethanolamine behenoyl lactylate, diethanolamine oleoyl lactylate, diethanolamine cocoyl lactylate, diethanolamine caproyl lactylate, potassium stearoyl lactylate, potassium behenoyl lactylate, potassium oleoyl lactylate, potassium cocoyl lactylate, potassium caproyl lactylate, calcium stearoyl lactylate, calcium behenoyl lactylate, calcium oleoyl lactylate, calcium cocoyl lactylate, calcium caproyl lactylate, ammonium sodium stearoyl lactylate, ammonium behenoyl lactylate, ammonium oleoyl lactylate, ammonium cocoyl lactylate, ammonium caproyl lactylate or combinations thereof, and

wherein said foamable composition produces a foam when passed through a non-aerosol foam dispenser.

2. The composition of claim 1 , wherein the amount of gemini surfactant relative to the di-ester is from about 0.6:1 to about 1.7:1 on a weight percent basis.

3. The composition of claim 1 , wherein said composition further comprises at least one foam booster.

4. The composition of claim 3 , wherein said foam booster is a cationic oligomer or polymer, a collagen amino acid, an amaranth protein, or a soluble elastin.

5. The composition of claim 3 , wherein the weight ratio of the gemini surfactant to foam booster is from about 3.5:1 to about 14.5:1.

6. An antimicrobial composition comprising:

at least 60 weight percent of a C 1-4 alcohol;

from about 0.1 to about 20 weight percent of a gemini surfactant;

from about 0.1 to about 20 weight percent of a di-ester surfactant; and

from about 0.005 to about 4 weight percent of an amaranth protein, wherein all weight percentages are based upon the total weight of the composition,

wherein said gemini surfactant is disodium ethylene dicocamide PEG-15 disulfate,

wherein said di-ester surfactant is selected from sodium sodium stearoyl lactylate, sodium behenoyl lactylate, sodium oleoyl lactylate, sodium cocoyl lactylate, sodium caproyl lactylate, lauroyl lactylic acid, myristoyl lactylic acid, triethanolamine stearoyl lactylate, triethanolamine behenoyl lactylate, triethanolamine oleoyl lactylate, triethanolamine cocoyl lactylate, triethanolamine caproyl lactylate, diethanolamine stearoyl lactylate, diethanolamine behenoyl lactylate, diethanolamine oleoyl lactylate, diethanolamine cocoyl lactylate, diethanolamine caproyl lactylate, potassium stearoyl lactylate, potassium behenoyl lactylate, potassium oleoyl lactylate, potassium cocoyl lactylate, potassium caproyl lactylate, calcium stearoyl lactylate, calcium behenoyl lactylate, calcium oleoyl lactylate, calcium cocoyl lactylate, calcium caproyl lactylate, ammonium sodium stearoyl lactylate, ammonium behenoyl lactylate, ammonium oleoyl lactylate, ammonium cocoyl lactylate, ammonium caproyl lactylate or combinations thereof, and

wherein said foamable composition produces a foam when passed through a non-aerosol foam dispenser.

7. The composition of claim 1 , wherein the composition further comprises one or more ingredients selected from emulsifiers, viscosity increasing agents, and detergents, wherein the total amount of emulsifiers, viscosity increasing agents, and detergents is from 0.1 to 1 wt. % based upon the total weight of the alcoholic composition.

8. The composition of claim 1 , wherein the composition further comprises auxiliary surfactant in an amount of from 0 to about 2 wt. % based upon the total weight of the alcoholic composition.
