Abstract
This invention relates to a high alcohol content aerosol antimicrobial mousse which is dispensed as a foam for use as an antiseptic. The mousse composition comprises (1) 85-98% of an intermediate concentrate and (2) 2-15% of a hydrocarbon propellant. The intermediate concentrate comprises from 52-75% by weight of ethanol or isopropyl alcohol; from 0.1% to 1.5% by weight of a water-dispersible polymeric gelling agent; an amphiphilic system consisting of from 0.5% to 5.0% by weight of (a) at least one alcohol with a hydrocarbon group of from 16 to 22 carbons and (b) at least one nonionic surfactant, the hydrophilic balance (HLB) of the combination components "a" and "b" is in the range of 4.5 to 8.0 and the balance being at least 20 wt % of water. The hydrocarbon propellant is a saturated aliphatic hydrocarbon having from 2 to 6 carbon atoms.
