  • Patent number: 5728663
    Abstract: The present invention relates to a clear colorless soap bar with superior mildness, lathering and discoloration resistance. The clear colorless soap consists of a blend of C12-C18 fatty acids neutralized with sodium hydroxide (NaOH) and triethanolamine (TEA). Excess TEA acts as a co-solvent and is responsible for clarity of the soap bar. The bar also contains a branched chain acid such as isostearic acid to break up crystallinity and add to product clarity. Low color and color stability are obtained by removing unsaturated fatty acids, and by the use of antioxidants (BHT and Vitamin E). Low levels of C6 to C10 fatty acids provide exceptional mildness.

    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.

  • Patent number: 5656579
    Abstract: The invention relates to mild toilet soap bars, comprising blends of soap with one or more coactives. There is a need for mild bars which do not have the processing problems associated with the use of superfatting agents and co-actives, which can be made without difficulty on conventional soap production lines without substantial modification of the lines and yet provide a product with reduced harshness while maintaining lathering and structural properties. Moreover, it is desirable that soap bars should not suffer from the defect of grittiness and also have a composition which contains relatively low levels of the significantly more expensive lauric fats. We have determined that in soap bars which comprise at least 25% wt. on total actives of lauric acid soaps; as the balance of the soaps, non-lauric soaps having an iodine value of less than 45; at least 5% wt.
