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 degrees F., (d) about 0.1-5% of one or more emollients, and (e) about 0.3-4% of a foam stabilizer component comprising about 0.1-3% 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.
