  • Patent number: 8846592
    Abstract: The present invention provides personal wash compositions where hydrogenated triglyceride oils (defined by IV of 0 to <20) are specifically formulated to provide low temperature stability. Specifically when formulated to have specific concentration of hydrogenated triglycerides, delivered as pure sample or from mixtures of hydrogenated and other triglyceride oils, desirable low temperature stability of formulations is achieved.

  • Patent number: 8268767
    Abstract: The present invention relates to super mild surfactant systems used in combination with skin or hair benefit agent(s). Specifically, surfactant systems comprise a combination of specific alkanoyls or mixtures of alkanoyl surfactants with specifically identified fatty acyl isethionate product to provide synergy which reduces irritation (as measured by Patch Testing) so greatly that it is comparable to mildness which normally can be only achieved using very great amounts of benefit agent (e.g., emollient). Use of benefit agent reduces irritation even further.

  • Patent number: 8124574
    Abstract: The present invention relates to liquid personal care composition comprising both low levels of specific fatty isethionate product (e.g., less than 4%) and low overall fatty acid content (less than 4%) which, quite surprisingly, maintain excellent foaming profile relative to identical composition having high overall fatty acid content.

  • Patent number: 8110533
    Abstract: A liquid cleansing composition is provided which includes from 5 to 25% by weight of a fatty acids mixture and from 30 to 90% by weight of water, wherein the fatty acids mixture is present in a weight amount greater than a total of all surfactants other than soap present in the composition. Further, the fatty acids mixture is 70-95% of lauric and myristic fatty acids in a weight ratio from 9:1 to 1:2, and 5-30% C16-C20 fatty acid, all by weight of the fatty acids mixture. Still further, 60-90 mole % of the fatty acids mixture is neutralized into soap.
