  • Liquid personal cleansing composition
    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.
    Type: Grant
    Filed: November 13, 2009
    Date of Patent: September 13, 2011
    Assignee: Conopco, Inc.
    Inventors: Anat Shiloach, Suzanne Lynn Gencarelli, Sirisha Muppidi, Michael A. Rahn, Rosa Mercedes Paredes
