US Classification:

510130, 510137, 510120, 510125, 510159, 510417, 510424, 510428, 510506, 510490

Abstract:

The present invention relates to a multiphase aqueous cleansing composition for cleansing human skin and hair, which when agitated forms a single application phase, and when left standing, the composition rapidly returns to an appearance having at least two visibly distinct aqueous phases. The multiphase aqueous cleansing composition of the present invention provides an esthetically interesting and useful cleansing composition for use as a body wash, shower gel, foam bath or shampoo. The aqueous multiphase cleansing composition comprises: a surfactant comprising a surfactant or salt thereof; one or more co-surfactants; a humectant; and a salt, wherein the cleansing composition is essentially free of a thickener or a detergent builder.

Abstract:

Compositions and methods are disclosed for producing pearlized compositions of alcoholic hydrogels at ambient temperatures. More particularly, compositions and methods are disclosed for pearlized alcoholic hydrogel compositions with stearyl alcohol at preparation temperatures below the melting point of stearyl alcohol, which is solid at room temperature. Pearlizing effects are achieved in alcoholic hydrogels at low temperatures by the addition to the alcoholic hydrogel of stearyl alcohol in a siloxane form as stearyl alcohol trialkylsiloxane. By incorporating the siloxane form of stearyl alcohol, which previously could be only handled at anhydrous conditions, into the hydroalcoholic gel, one obtained a stable pearlized alcoholic hydrogel having a lustrous pearlescent appearance. Preparation was accomplished without heating above room temperature, without a pearlescent wax, and without a potentially skin irritating surfactant.
