High alcohol content foaming compositions with silicone-based surfactants

Abstract

This invention relates to a “high lower alcohol content”(>40% v/v of a C 1-4 alcohol) liquid composition 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, C 1-4 (>40% v/v), a silicone-based surfactant 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), 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.
