US 8,940,674 B2 · High alcohol content foaming compositions

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.

Dependent claims

A composition, comprising:

a) an alcohol C1-4, or mixtures thereof, present in an amount greater than or equal to about 60% v/v of the total composition;
b) an effective fluorinated surface active agent for wetting and foaming present in an amount of at least 0.001% by weight of the total composition wherein the fluorinated surface active agent is selected from the group consisting of fluorinated glycerol esters, amine oxides, acetylenic alcohol derivatives, carboxylates, phosphates, carbohydrate derivatives, sulfonates, betaines, esters, polyamides, and hydrocarbon surfactants;
and
c) water present in an amount to balance the total composition to 100% by weight.

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 fluorinated surface active agent 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;
wherein the effective physiologically acceptable fluorinated surface active agent is selected from the group consisting of fluorinated glycerol esters, amine oxides, acetylenic alcohol derivatives, carboxylates, phosphates, carbohydrate derivatives, sulfonates, betaines, esters, polyamides, hydrocarbon surfactants, and combinations thereof.

A method for personal disinfecting comprising:

applying to a person's skin a skin-disinfecting alcohol foam composition which comprises
a) air mixed under low pressure with
b) a liquid comprising
i) an alcohol C1-4, or mixtures thereof, present in an amount greater than or equal to about 60% v/v of the total composition;
ii) water present in an amount to balance the total composition to 100% by weight;
and
iii) a physiologically acceptable effective fluorinated surface active agent for foaming present in an amount of at least 0.001% by weight of the total composition,
wherein the effective physiologically acceptable fluorinated surface active agent is selected from the group consisting of fluorinated glycerol esters, amine oxides, acetylenic alcohol derivatives, carboxylates, phosphates, carbohydrate derivatives, sulfonates, betaines, esters, polyamides, hydrocarbon surfactants and combinations thereof.
