An improved instant foaming aerosol shave cream is provided which includes, in percent by weight of the entire composition, (a) about 70-90 % water, (b) about 10-20 % of a soap component comprising about 8-12 % of an alkanolamine C14-C18 fatty acid soap and about 2-4 % of a nonionic surfactant having an HLB of at least about 15, (c) about 1-5 % of a propellant having a vapor pressure of about 30-60 Psig at 70 DEG F, (d) about 0.1-5 % of one or more emollients, and (e) about 0.3-4 % of a foam stabilizer component comprising about 0.2-2 % of a fatty alcohol, about 0.1-3 % of a fatty alkanolamide, and about 0.01-0.6 % of a fatty acid diester of polyethylene glycol having a molecular weight of at least about 1000. The compositions are oil-in-water emulsions and exhibit advantages associated with delayed-foaming shaving gels but with the convenience of instant foams. |
