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 the steps of;
- a) dispensing a foamable alcohol composition from a container having a dispenser pump configured to mix air with the foamable alcohol composition 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 40% v/v of the total composition;
ii) an effective physiologically acceptable silicone-based surfactant, comprising a lipophilic chain containing a silicone backbone for wetting and foaming present in an amount of at least 0.01% weight percent of the total composition; and
iii) water present in an amount to balance the total composition to 100% weight percent.

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.

31. A method of use of an alcohol foam composition for personal disinfecting, the method of use comprising providing an alcohol foam composition comprising;
-
a) air mixed under low pressure conditions; and
b) a liquid comprising i) a C1-4 alcohol, or mixtures thereof, present in an amount greater than about 60% v/v of the total composition;
ii) an physiologically acceptable silicone-based surfactant having a lipophilic chain containing a silicone backbone, for wetting and foaming present in an amount of at least 0.01% weight percent of the total composition; and
iii) water present in an amount to balance the total composition to 100% weight percent. - View Dependent Claims (32, 33, 34, 35, 36)

37. A method for producing, and applying to a person'"'"'s skin, a skin-disinfecting alcohol foam composition, comprising
a) combining an alcohol C1-4, or mixtures thereof, present in an amount greater than about 60% v/v of the total composition with an effective physiologically acceptable silicone-based surfactant 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 to form an alcohol/silicone-based surfactant mixture and storing said composition in an unpressurized dispenser having a dispenser pump; -
b) activating the dispenser pump to combine the alcohol/silicone-based surfactant mixture with air to form and dispense a skin-disinfecting alcohol foam; and
c) applying the skin-disinfecting alcohol foam to the person'"'"'s skin. - View Dependent Claims (38, 39, 40, 41, 42)
