    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: 4792619
    Abstract: Textile cellulose material is printed or dyed with reactive dyes with the aid of foam. The foam is applied by applying to the cellulose material a foamed, aqueous preparation which contains in addition to dyes and fixing alkalis(1) a foam-forming agent(2) a homopolymer or copolymer of acrylamide or methacrylamide or preferably a graft polymer which is obtained from an addition product of an alkylene oxide, preferably propylene oxide, on an at least trihydric aliphatic alcohol, e.g. glycerol, and acrylamide or methacrylamide, and(3) a betainelike quaternary ammonium salt which is obtainable by condensation of (A) a sulfonated asymmetric succinic acid diester which has as ester groups a halohydrin group and an etherified polyalkylene glycol group, with (B) a tertiary amine-substituted N-alkylamide of ethylenically unsaturated aliphatic monocarboxylic or dicarboxylic acid.The cellulose material thus treated is then subjected to a heat treatment, for example steaming, to fix the dye.
