Patent Images
1. A foamable composition comprising:
- at least 40 weight percent alcohol, based upon the total weight of the alcoholic composition;
a foaming surfactant selected from the group consisting of anionic, cationic, and zwitterionic fluorosurfactants, and combinations thereof; and
a polymeric or oligomeric foam stabilizer selected from the group consisting of polyquaterniums, quaternized copolymers of vinylpyrrolidone and dimethylamino methacrylate, hydrophobically modified quaternized copolymers of vinylpyrrolidone &
dimethylaminopropyl methacrylamide, and mixtures thereof, wherein the weight ratio of foaming surfactant to foam stabilizer is from about 3.5;
1 to about 14.5;

10. A method for forming stabilized alcoholic foam, the method comprising:
-
combining an alcohol, a foaming surfactant selected from the group consisting of anionic, cationic, and zwitterionic fluorosurfactants and combinations thereof, and a polymeric or oligomeric foam stabilizer selected from the group consisting of polyquaterniums, quaternized copolymers of vinylpyrrolidone and dimethylamino methacrylate, hydrophobically modified quaternized copolymers of vinylpyrrolidone &
dimethylaminopropyl methacrylamide, and mixtures thereof, to form a foamable alcoholic composition, wherein the weight ratio of foaming surfactant to foam stabilizer is from about 3.5;
1 to about 14.5;
1;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 40 percent by weight alcohol, based upon the total weight of the alcoholic composition. - View Dependent Claims (11, 12, 13)
