  • Patent number: 10646414
    Abstract: The invention provides a personal cleansing composition having an aqueous continuous phase including cleansing surfactant and a solubilised hydrocarbon oil having a kinematic viscosity of 1 to 35 cSt at 40° C. and a specific gravity of 0.76 to 0.87 at 25° C.; in which the hydrocarbon oil is solubilised in wormlike micelles in the aqueous continuous phase by means of a linker molecule and an inorganic electrolyte; in which the linker molecule is selected from one or more compounds of formula: R(X)n, in which R is a C6 to C14 mono-, di- or trivalent saturated aliphatic or an aromatic hydrocarbyl group, n is 1 to 3 and each X is independently selected from —OH and —COOH; and in which the level of hydrocarbon oil in the composition ranges from 0.8 to 1.5% by weight based on the total weight of the composition.

  • Publication number: 20170020793
    Abstract: The present invention relates to personal wash compositions, in particular shampoo compositions comprising beneficial oils. It has been a long felt need to solubilise beneficial oils such as mineral oil in wormlike micelles in surfactant systems. It is therefore an object of the present invention to provide a personal wash composition comprising functional levels of beneficial oil such as mineral oil. It has been found that mineral oil can be solubilised in wormlike micelles in a surfactant system with specific hydrophilic or lipophilic linker molecules.
