ABSTRACT:
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.
