  • Publication number: 20040047830
    Abstract: A shaving cream composition and method is provided wherein the cream composition is packaged in an aerosol dispenser and includes a propellant system of dimethyl ether and hydrocarbon, an anionic surfactant, a fatty alcohol and a hydrophobic emollient. Total weight ratio of all hydrophobic emollients to all anionic surfactants ranges from about 50:1 to greater than about 1:1.

  • Patent number: 5639448
    Abstract: A method of thermally setting hair including the sequential steps of:(a) applying a thermoplastic polyester fixative resin composition, having a pH less than about 5, to the hair prior to configuring the hair in a desired configuration;(b) contacting the hair with a thermal appliance to heat the applied polyester to its glaze transition temperature;(c) configuring the hair while the polyester is at a temperature of at least its glass transition temperature; and(d) cooling the polyester to a temperature below its glass transition temperature while the hair is in the desired configuration to harden the polyester in the shape of the configured hair. Preferably, the thermoplastic polyester fixative resin includes a plurality of neutralized sulfonate moieties, and has a glass transition temperature below about 120.degree. C., and is solubilized or dispersed in water in an amount of about 0.1% to about 20%.
