  • Publication number: 20050136011
    Abstract: A hair conditioning foamed mousse product is provided which is housed in a pressurized canister fitted with valve having total orifice of at least 0.0002 in2 (0.13 mm2). The canister is filled with a cationic surfactant, a high molecular weight silicone, a low molecular weight silicone and a propellant. Advantageously the ratio of low to high molecular weight silicone ranges from 10:1 to 1:10. The low molecular weight silicone in amounts less than 1% counters the anti-foaming effect of the high molecular weight silicone thereby allowing formation of a stable light/airy foam. Also provided is a method for conditioning hair with mousse product applied to hair within a shower stall.
