  • Patent number: 5977037
    Abstract: A personal cleansing product comprising:(a) from about 0.1% to about 20% of anionic surfactant,(b) from about 0.1% to about 20% of amphoteric surfactant,(c) from about 0.5% to about 25% of a vegetable oil adduct and,(d) water.The vegetable oil adduct can be made by Diels-Alder addition of a conjugated, elaidinized form of the vegetable oil with acrylic acid, fumaric acid or maleic anhydride. The preferred adduct is maleated soybean oil. The compositions provide excellent in-use and efficacy benefits including cleansing and lathering as well as improved mildness and skin conditioning.

  • Patent number: 5942477
    Abstract: A personal cleansing product comprising:(a) from about 5% to about 50% by weight of a mixed surfactant system which comprises:(i) from about 1% to about 20% by weight of composition of anionic surfactant, and(ii) from about 1% to about 20% by weight of composition of amphoteric surfactant,(b) from about 3% to about 40% by weight of an insoluble nonionic oil or wax, and(c) water,wherein the anionic surfactant and amphoteric surfactant together comprise from about 5% to about 30% by weight of the composition, the weight ratio of anionic surfactant:amphoteric surfactant is in the range from about 1:5 to about 20:1, the weight ratio of total surfactant: nonionic oil or wax is in the range from about 10:1 to about 1:3, and wherein the composition is in the form of an oil-in-water emulsion having a viscosity in the range from 10,000 to 40,000 cps and a yield point of at least 50 dyne/cm.sup.2. The cleansing products demonstrate excellent lathering, mildness, stability, rinsibility and conditioning benefits.
