Abstract
A monohydric alcohol-free, transparent, moisturizing bar soap having a high humectant solvent content. The formulation includes: (i) from about 38% to about 96% of one or more humectant solvents and (ii) from about 3% to about 20% of insoluble and/or soluble fatty acid soaps, with at least about 3% insoluble fatty acid soap. The weight ratio of humectant solvent to insoluble fatty acid soap ranges from about 3:1 to about 23:1. The bar soap has a standardized wear rate of less than about 15% and a hardness of from about 30 to about 100 hardness units. The transparent solid bar soap may be manufactured by a 'hot pour' process with conventional batch mixing equipment designed for relatively moderate temperatures; accordingly, the bar soap may be packaged for final consumer use in the mold in which it was formed.
