  • Patent number: 7163692
    Abstract: A substantially dry personal care cleansing article is provided which includes a water-insoluble substrate and associated with the substrate a personal care cleansing composition. The latter includes at least one lathering surfactant and at least about 2% of a cationic polymer. The composition has an average particle size ranging from about 75 to about 900 micron. The cationic polymer improves the rapidity and duration of foam formation when the article is wetted with water to activate the surfactant.
