Soap- and Foam-Free Gel Patented by L’Oréal

US Patent No. 8,535,652 B2; L’Oréal, Paris, has patented a soap-free, self-foaming gel packaged in an aerosol container with a piston or flexible pocket separator to separate the gel from propellant necessary for ejecting the gel. The gel comprises, in a cosmetically acceptable medium, at least one aqueous phase; at least one N-acylsarcosine where the acyl radical is a C10-C20 radical; at least one mineral or organic base in an amount sufficient to dissolve the N-acylsarcosine and produce a pH of 4 to 8; at least one alkylbetaine; at least one nonionic surfactant; and at least one self-foaming agent. The gel is soap-free and is substantially foam-free until it is spread onto the skin, at which time it foams by evaporation of the self-foaming agent.
