Translucent soap cakes, which preferably are transparent, are made from mixed tallow and coconut oil soaps (or equivalents), lanolin soap and/or lanolin fatty acids and/or lanolin and/or other suitable derivative(s) thereof, and mixtures thereof, and water. Soap cakes or tablets of improved translucency (transparency) result when the lanolin soap, lanolin fatty acid, lanolin or suitable derivative thereof, or any mixture thereof is mixed at elevated temperature with substantially all of other soap cake components, except perfume (and possibly some other relatively minor constituents), and the resulting mixture is partially dried at elevated temperature, worked, extruded, cut into blanks and pressed to shape. The translucent soap cakes resulting, which may preferably be superfatted and contain a suitable antibacterial component, lather well, are of stable translucency on storage and are desirably mild to the skin. Translucency of the product may be further improved when there is also present in the soap cake formula a soap crystallization inhibiting polyol of 3 to 6 carbon atoms and 2 to 6 hydroxyl groups, such as glycerol or sorbitol. Also described are translucent soap-synthetic detergent cakes, variegated and at least partially translucent soap cakes and soap-syndet tablets, and pearlescent and at least partially translucent such products. Improved manufacturing processes are disclosed and an improved method for measuring product translucency is described. |
