This invention relates to a monohydric alcohol free process for making transparent pour molded personal cleansing bars which exhibit good hardness characteristics. The process comprises: (I) making a molten mixture of from 18 parts to 35 parts soap, wherein said soap is at least 50% insoluble sodium soap; from 14 parts to 32 parts water; from 5 parts to 37 parts synthetic surfactant; and from 18 parts to 37 parts of a water soluble organic solvent, wherein the combined level of water and water soluble organic solvent within the molten mixture is at least 40 parts; and (II) transferring a unit amount of said molten mixture into a bar forming mold or tube and (III) allowing said molded unit to cool in acquiescent conditions into a mild, low smearing transparent personal cleansing bar. The preferred bars made by the process of the present invention are more weight stable than bars made with several parts of alcohol. An important benefit of this invention is that bar processing time is substantially reduced by faster crystallization and faster bar stabilization. |
