First Claim
Patent Images
1. A foamable composition comprising:
- at least about 40 weight percent alcohol, based upon the total weight of the alcoholic composition; and
a foaming surfactant selected from the group consisting of siloxane polymer surfactants, anionic, cationic, and zwitterionic fluorosurfactants, and combinations thereof;
with the proviso that where the foaming surfactant comprises a fluorosurfactant, the foamable alcoholic composition further comprises a polymeric or oligomeric foam stabilizer.

Abstract
A stable foam composition includes greater than about 40 weight percent of an alcohol, based upon the total weight of the alcoholic composition, and a foaming surfactant selected from fluorosurfactants, siloxane polymer surfactants, and combinations thereof. When the foaming surfactant includes a fluorosurfactant, the alcoholic composition further includes a polymeric or oligomeric foam stabilizer.

25. A method for forming stabilized alcoholic foam, the method comprising:
-
combining an alcohol, a foaming surfactant selected from the group consisting of siloxane polymer surfactants, anionic, cationic, and zwitterionic fluorosurfactants and combinations thereof, to form a foamable alcoholic composition;
mixing said alcoholic composition and air or an inert gas in a mixing chamber to form a mixture; and
passing said mixture through a mesh screen to form a foam, wherein said foamable alcoholic composition comprises at least about 40 percent by weight alcohol, based upon the total weight of the alcoholic composition, and with the proviso that, when the foaming surfactant comprises a fluorosurfactant, the foamable alcoholic composition further comprises a polymeric or oligomeric foam stabilizer. - View Dependent Claims (26, 27)
