Abstract
Formulations for transparent soaps and methods of preparation are disclosed. The transparent soaps are prepared by combining high and low molecular weight fatty acids in the presence of polyhydric alcohols. Citric acid is added to adjust pH. The formulations do not require volatile, short-chain monohydric alcohols to achieve transparency and the end products are able to retain transparent qualities when exposed to hot water conditions. Suitable formulations can be remelted to reduce waste.

- (r) a transparency enhancing amount of 5.0 to about 15.0% water.
A method for making transparent soap which comprises the following steps:
- (a) heating a composite of selected polyols to a first temperature range;
- (b) heating a transparency enhancing amount of a blend of selected tallow and vegetable fatty acids to about the temperature range of said polyol composite;
- (c) mixing said blend with said polyol composite at a second temperature range;
- (d) adding a transparency enhancing amount of a 50% aqueous solution of sodium hydroxide to said mixture of step (c) at a temperature not to exceed about 195.degree. F.;
- (e) adding heated, aqueous sodium chloride solution to the mixture of step (d) and mixing at a third temperature range until all ingredients are solubilized;
