ABSTRACT OF INVENTION A sprayable germicidal foam composition containing a therapeutically sufficient quantity of the microbicidally active agent; an aliphatic fatty alcohol and an aliphatic fatty acid, each agent being in critical ratio to each other, in parts by weight of from 1:2 with a preferred range for this critical ratio of from 0.5 parts to 2.0 parts by weight of the fatty alcohol, to 1 to 3 parts by weight of the fatty acid; a nonionic surface tension reducing agent in concen- tration of at least equal to one-half of the combined weight of the fatty alcohol and fatty acid moieties but not greater than three times the weight of the fattyalcohol present; and aqueous-aliphatic glycol mixture, in critical proportion offrom 1 part aliphatic glycol to 15 parts of water, with a preferred range of critical ratio of from 0.5 to 1.5 parts by weight of said glycol, to 7.5 parts to 30 parts by weight of water, and a suitable aerosol propellant, in sufficient quantity to provide a ratio of from 0.5 parts to 3 parts by weight of said pro- pellant to 7 to 9.5 parts by weight of sprayable composition, the whole being packaged in a pressurized container fitted with a release valve. When the con- tainer pressure is released, a durable foam is extruded to provide a safe and effective, pain-free, germicidal barrier to burned, abraded or wounded skin and mucous membranes of humans and animals, when applied form 1 to 6 times daily. -1-
