US 7,199,090 B2 · High alcohol content gel-like and foaming compositions comprising an alcohol and 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 mosturizers, 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.

Dependent claims

A foamable composition, comprising;

a) an alcohol C1-4, or mixtures thereof, present in an amount greater than about 40% 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 weight percent of the total composition, wherein the fluorinated surface active agent is an anionic phosphate fluorosurfactant of the following structure:
(RfCH2CH2O)x P(O2)− (NH4)+y, where Rf=F(CF2 CF2)z, x=1 or 2, y=2 or 1, x=y=3, and z=1 to about 7, and
c) water present in an amount to balance the total composition to 100 weight percent.

1 more element

A foamable alcohol disinfecting composition, comprising;

a) an alcohol C1-4, or mixtures thereof, present in an amount between about 60% to about 80% v/v of the total composition;
b) a physiologically acceptable fluorosurfactant present in an amount from about 0.01 to about 2.0 weight percent of the total composition, wherein said fluorosurfactant is an anionic phosphate fluorosurfactant of the following structure:
(RfCH2CH2O)x P(O2)−(NH4)+y, where Rf=F(CF2 CH2)z, x=1 or 2, y=2 or 1, x+y=3, and z=1 to about 7, and
c) a foam stabilizing agent present in an amount from about 0.01 to about 12.0 weight percent;
d) any one of moisturizers, emollients and combinations thereof present in an amount from about 0.05 to about 5.0 weight percent;
and
e) water in an amount to balance the total composition to 100 weight percent.

4 more elements

A foamable alcohol disinfecting composition, comprising;

a) an alcohol C1-4, or mixtures thereof, present in an amount between about 60% to about 80% v/v of the total composition;
b) a physiologically acceptable fluorosurfactant present in an amount from about 0.01 to about 2.0 weight percent of the total composition, wherein said fluorosurfactant is an amphoteric polytetrafluoroethylene acetoxypropyl betaine (CF3CF2(CF2CF2)nCH2CH2(OAc)CH2N+(CH3)2CH2COO−) where n=2 to 4;
c) a foam stabilizing agent present in an amount from about 0.01 to about 12.0 weight percent;
