A low water content cleansing composition in toilet bar form is described which includes high levels of emollients having a melting point below 25 C., 12-hydroxystearic acid as a structuring agent, and at least one detersive surfactant. Useful emollients that are liquid at room temperature may include triglycerides, petroleum oil, polyhydric alcohols and silicone oil, and are present in a concentration range of 5 to 60 wt. %. The inventive toilet bars have excellent mush and wear properties.

Skin cleansing bar with high levels of liquid emollient

A multi-phase solid toilet article whose phases are separated by a membrane, and processes for making the article are described. Each phase is reproducibly fabricated to form an article allowing the user to sequentially or simultaneously derive benefits from the different materials contained in the article's layers. The membrane is either at least partially water soluble or dispersible in the case of a product used with water, or shearable in the case of a cosmetic product which is applied directly to or rubbed on the skin. The membrane material is selected to dissolve or disintegrate with product use, so as to accomplish its intended function of separating the different cosmetic materials until they are consumed. The flowable toilet or cosmetic formulations are simultaneously or separately transferred into the mold, simultaneously or separately allowed to harden, where the membrane divider is not removed and becomes a part of the finished product. The hardened multi-phase article is finally ejected from the mold.

Multi-phase toilet articles and methods for their manufacture

A cleansing bar composition is described comprising an anionic surfactant, a C6 to C18 free fatty acid, and a fatty alcohol having a melting point under about 35&deg;C.  and optionally a hydrophobic emollient. Useful emolients include triglycerides, hydrocarbons, silicones, fatty esters, and mixtures thereof. Useful anionic surfactants include C8 to C18 alkali metal acyl isethionates. Suitable low melting fatty alcohols include lauryl alcohol, oleyl alcohol, and a mixture thereof. The inventive bars have excellent mush, lather and wear properties.
