US 7,683,018 B2 · High alcohol content gel-like and foaming compositions comprising an anionic phosphate fluorosurfactant

Abstract

This invention relates to a “high lower alcohol content” (>40% v/v of a C1-4 alcohol) liquid composition able to be either dispensed as a stable foam with the use of non-propellant foam dispensing devices from non-pressurized containers or as an alcohol gel composition which does not use thickener and gelling agents that leave undesirable deposits or a sticky after-feel and that has a final viscosity less than 4,000 cps. 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 or from 0-2.0% to prepare a gel-like composition of a final viscosity less than 4,000 cps, 0-10% w/w of additional minor components added to obtain the desired performance (a foamable composition or a gel-like 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.

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 60% by weight of the total composition, a physiologically acceptable effective anionic phosphate fluorosurfactant for foaming present in an amount of at least 0.001% by weight percent of the total composition, and water present in an amount to balance the total composition to 100% by weight.
