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:

Superfatted personal cleansing bar containing alkyl polyglycoside

A translucent personal cleansing bar containing: (a) an alkyl polyglycoside of formula I:

Translucent personal cleansing bars

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:

Process for making skin cleansing combination soap bars and cleansing

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.

Abrasive-containing soap bars

Fatty acid esters of isethionate salts are made by reacting ethylene oxide and a bisulfite salt in an aqueous solution while maintaining the pH in the range of from about 5.5 to about 6.5 and while maintaining the temperature in the range of from 25.degree. C. to 85.degree. C. to form an isethionate salt. The isethionate salt is then esterified with a fatty acid to produce a product having little or no unwanted fatty acid esters of ethylene glycol.

Process for making isethionate ester salts

Fatty acid esters of isethionate salts are made by reacting ethylene oxide and a bisulfite salt, that may be made in situ, in aqueous ammonia while maintaining (1) the pH in the range of about 5.5 to about 6.5 and (2) the temperature in the range of 25.degree. C. to 85.degree. C. to form an isethionate salt. The isethionate salt is then esterified with a fatty acid to produce a product having little or no unwanted fatty acid esters of ethylene glycol.

Quaternary ammonium salts of fatty acid hydroxyalkanesulfonic acids are made by reacting a hydroxyalkanesulfonic acid of the formula (I):

Process for the production of quaternary ammonium salts of fatty acid

Ammonium fatty acid hydroxyalkanesulfonates are made by a process in which (a) ammonium hydroxyalkanesulfonate corresponding to general formula (I):
