Abstract: A process for making a superfatted personal cleansing bar involving the steps of: (a) providing a solid-form superfatting agent consisting of: (i) a fatty component selected from the group consisting of C.sub.6 -C.sub.22 free fatty acids, C.sub.6 -C.sub.22 fatty alcohols, and mixtures thereof; and (ii) a nonionic sugar surfactant selected from the group consisting of an alkyl polyglycoside of formula I:R.sub.1 O(Z).sub.a Iwherein R.sub.1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; and a is a number having a value from 1 to about 6, a polyhydroxy fatty acid amide, and mixtures thereof; (b) providing a solid-form neutralized tallow/coco fatty acid soap mixture; (c) mixing components (a) and (b) to form a superfatted soap bar stock; and (d) stamping the superfatted soap bar stock into a finished personal cleansing bar.

Abstract: A translucent personal cleansing bar containing: (a) an alkyl polyglycoside of formula I:R.sub.1 O(Z).sub.a (I)wherein R.sub.1 is a monovalent organic radical having from about 8 to 10 carbon atoms, and a is a number having a value of from about 1.40 to 1.55; (b) a soap component; and (c) water.

Abstract: A surfactant composition consisting essentially of: (a) from about 20 to about 63% by weight of an acyl isethionate; (b) from about 3 to about 52% by weight of a nonionic sugar surfactant selected from the group consisting of alkyl glucose esters, aldobionamides, gluconamides, glyceramides, glyceroglycolipids, polyhydroxy fatty acid amides, alkyl polyglycosides having the general formula I:R.sub.1 O(R.sub.2 O).sub.b (Z).sub.a Iwherein R.sub.1 is a monovalent organic radical having from about 6 to about 30 carbon atoms; R.sub.2 is a divalent alkylene radical having from 2 to 4 carbon atoms; Z is a saccharide residue having 5 or 6 carbon atoms; b is a number having a value from 0 to about 12; a is a number having a value from 1 to about 6, and mixtures thereof; (c) from about 7 to about 23% by weight of a free fatty acid; and (d) remainder, water, all weights being based on the weight of the surfactant composition.

Abstract: A soap bar useful for removing heavy amounts of soil from the skin is comprised of a fatty acid soap, a fatty acid ester of an isethionate salt, a nonionic sugar surfactant selected from the group consisting of an alkyl glucose ester, an aldobionamide, a gluconamide, a glyceramide, a glyceroglycolipid, a polyhydroxy fatty acid amide, an alkyl polyglycoside, and combinations thereof, an abrasive and, water.

Abstract: Quaternary ammonium salts of fatty acid hydroxyalkanesulfonic acids are made by reacting a hydroxyalkanesulfonic acid of the formula (I):HO--(C.sub.n H.sub.2n)--SO.sub.3 H (I):wherein n=2 to 4 with a fatty acid having from 6 to 18 carbon atoms at a temperature range of from about 60.degree. C. to about 120.degree. C. and at a reduced pressure followed b reaction with an amine in an organic solvent.

Abstract: Ammonium fatty acid hydroxyalkanesulfonates are made by a process in which (a) ammonium hydroxyalkanesulfonate corresponding to general formula (I):HO--(C.sub.n H.sub.2n)--SO.sub.3 NH.sub.4 (I)wherein n=2 to 4, is subjected to the esterification reaction with a fatty acid corresponding to the formula (II)R--COOH (II)wherein RCO is an aliphatic, linear or branched acyl radical containing 6 to 18 carbon atoms, in the presence of an esterification catalyst, characterized in that (a) before the esterification reaction, the starting compounds corresponding to formulae (I) and (II) are dried at a temperature of 120.degree. C. to 160.degree. C. and under a pressure of 100 to 700 mbar; (b) the esterification reaction is carried out at a temperature above 160.degree. C. to 195.degree. C. and under a pressure of 250 mbar to atmospheric pressure; (c) water of solution and water of reaction formed are directly removed from the reaction mixture; (d) the catalyst is neutralized with a base on completion of the reaction.
