Abstract
The present invention encompasses a personal cleansing bar comprising from 10 parts to 70 parts by bar weight of a distilled, topped C.sub.12 -C.sub.18 acyl (topped cocoyl) isethionate (STCI). The bar of this invention contains little or no (0-2.8 parts) highly soluble acyl groups (sodium C.sub.6, C.sub.8, C.sub.10, C.sub.18:1 and C.sub.18:2 acyl isethionate). The bar of this invention is mild, smells better than a bar made with ordinary sodium cocoyl isethionate (SCI), is more stable in terms of both odor and color, and is easier to make. A preferred STCI bar contains a higher level of moisture without processing negatives which higher level of moisture contributes to better lather. The sodium topped cocoyl isethionate (STCI) also allows for an increase in levels of liquids and hygroscopic materials, in the bar formulation without the usual processing negatives.
