  • Patent number: 11760889
    Abstract: Sulfate and sulfonate derivatives of unsaturated fatty alcohols, processes for making them, and methods of using them are disclosed. In one aspect, a monounsaturated fatty alcohol composition is made by reducing a metathesis-derived monounsaturated alkyl ester. The fatty alcohol composition is then converted to a sulfate or sulfonate derivative by one or more of alkoxylation, sulfation, sulfonation, and sulfitation. Of particular interest are the sulfate and ether sulfate derivatives. Microscopy studies indicate that the unsaturated sodium sulfates in particular have a lamellar phase that should enable formulation at high actives levels. Sulfate compositions comprising 40 to 60 wt. % of a monounsaturated fatty primary alcohol sulfate and 40 to 60 wt. % of a secondary hydroxyalkyl primary alcohol sulfate are also disclosed.

  • Patent number: 7833956
    Abstract: A cleansing composition comprising a water-compatible emollient that provides enhanced skin-feel characteristics, as well as viscosity-building properties. The water-compatible emollient is an alkoxylated derivative of glyceryl cocoate containing both propylene oxide and ethylene oxide groups in the molecular structure. The cleansing composition also comprises one or more surfactants, and optional additives, and can be formulated into a body wash, shampoo, facial cleanser, liquid hand soap, dish detergent or car wash detergent.
