High alcohol content foaming compositions comprising an anionic phosphate fluorosurfactant
First Claim
1. A method of forming a skin disinfecting foam containing alcohol, comprising the steps of:
- activating a dispenser pump of an unpressurized dispenser to combine an alcohol-fluorosurfactant mixture with air to form and dispense a skin disinfecting foam containing alcohol, wherein the alcohol-fluorosurfactant mixture comprises an alcohol C1-4, or mixtures thereof, present in an amount greater than or equal to about 60% v/v of the total composition, a physiologically acceptable effective anionic phosphate fluorosurfactant for foaming present in an amount of at least 0.001% by weight of the total composition, and water present in an amount to balance the total composition to 100% by weight.

Abstract
A “high lower alcohol content” (>40% v/v of a C1-4 alcohol) liquid composition is able to be dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers. The liquid compositions comprise an alcohol, C1-4 (>40% v/v), a fluorosurfactant of at least 0.001% by weight to prepare a foamable composition, 0-10% w/w of additional minor components added to obtain the desired performance (a foamable composition with a viscosity less than 4,000 cps), and the balance being purified water. The compositions may include emulsifier-emollients and moisturizers, secondary surfactants, foam stabilizers, fragrances, antimicrobial agents, other type of medicinal ingredients, and the like ingredients or additives or combinations thereof commonly added to alcohol gels or foams, aerosol compositions or to toiletries, cosmetics, pharmaceuticals and the like.
