Method of producing high alcohol content foaming compositions with silicone-based surfactants
First Claim
1. A method of producing and dispensing a foam using a foamable alcohol composition, the method comprising:
- dispensing a foamable alcohol composition from a container having a dispenser pump configured to mix air with the foamable alcohol composition under low pressure during dispensing to form a foam, the foamable alcohol composition comprising;
i) a C1-4 alcohol, or mixtures thereof, present in an amount greater than 60% v/v of the total composition;
ii) an effective physiologically acceptable silicone-based surfactant, comprising a lipophilic chain containing a silicone backbone for foaming present in an amount of at least 0.5% by weight of the total composition; and
iii) water present in an amount to balance the total composition to 100% by weight.

Abstract
This invention relates to a method of producing and dispensing a foam using a “high lower alcohol content”(>40% v/v of a C1-4 alcohol) liquid composition. The liquid compositions comprise an alcohol, C1-4(>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.
