  • Patent number: 8691197
    Abstract: This invention relates to rinse-off skin conditioning compositions comprising relatively low amounts of oil/emollient and relatively low amounts of aqueous phase stabilizer/structurant. Use of unsaturated fatty acid (or at least minimum amount of unsaturated fatty acid as percentage of total fatty acid) has been found to result in unexpectedly high hydration. In a second embodiment, use of branched fatty acid (at minimum amount branched as percentage of total) also results in superior hydration. Also mixtures of unsaturated and branched fatty acids can be used. In a second embodiment, the invention relates to method of enhancing hydration using compositions as noted.

  • Patent number: 8017566
    Abstract: A mild, substantially isotropic skin cleansing solution was found to be able to suspend insoluble components and provide copious amounts of lather. The cleanser is formulated with synthetic anionic surfactants and a specific ratio of carboxylic acid(s) to hydrophobically modified cross-linked acrylate copolymer(s). The carboxylic acid and acrylate polymer combination were found to provide a synergistic effect on zero shear viscosity at 25 C in a specific pH and copolymer/acid concentration ratio range.

  • Patent number: 7977289
    Abstract: The invention relates to substantially surfactant free gel compositions comprising hydrophobic and hydrophilic benefit agents. Unexpectedly, the applicants have found these agents deposit with greater substantivity from such liquid gel compositions relative to surfactant-containing lotion.

  • Publication number: 20040202632
    Abstract: A solid cosmetic composition is described including a water dissolvable solid carrier incorporating at least one cosmetic agent. The solid carrier is a destructurized starch material. Fragrance is applied topically onto the solid carrier. The compositions are best formed into tablets, pellets, beads or sheet articles. Particularly preferred is where the solid cosmetic composition and carrier are foamed.
