With Free Higher Fatty Acid Component Patents (Class 510/153)
  • Patent number: 5965500
    Abstract: The present invention provides high foaming aqueous liquid compositions with levels of oil/emollient equal to or in excess of level of surfactant. It is surprising that good levels of foam can be maintained at such high levels of emollient. In addition to surfactant and emollient, compositions also preferably comprise C.sub.12 -C.sub.24 fatty acid and/or cationic polymer.

  • Patent number: 5908707
    Abstract: Wet-like cleaning wipes and similar articles are described. These wipes comprise a carrier that provides controlled fluid absorbency and an emulsion applied to the carrier. The emulsion comprises a continuous external lipid phase and a polar (e.g., water) internal phase. The emulsion is sufficiently brittle that it ruptures when subjected to low shear pressures during use to release the dispersed polar phase. The carrier allows the released internal phase to initially reach and remain on the surface being cleaned, but then absorbs the material at the end of the wiping process.

  • 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.

  • Patent number: 5681980
    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.
