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.
