  • Patent number: 5985809
    Abstract: A personal cleansing composition comprising: (a) from about 1% to about 30% by weight of a dispersed oil phase comprising at least one nonocclusive liquid polyol fatty acid polyester containing at least four fatty acid ester groups wherein the polyol moiety is selected from sugars and sugar alcohols containing from about 4 to about 8 hydroxyl groups, and wherein each carboxylic acid moiety has from about 8 to about 22 carbon atoms and wherein the liquid polyol fatty acid polyester has a complete melting point of less than about 30.degree. C.; and (b) from about 5% to about 30% by weight of water-soluble surfactant selected from anionic, nonionic, zwitterionic and amphoteric surfactants and mixtures thereof. The products provide excellent in-use and efficacy benefits including excellent skin feel during and after use, good lather volume and stability characteristics, skin conditioning, mildness, stability, cleansing, good water-feel and appearance.
