Filed:

Feb 7, 1996

Appl. No.:

8/598159

Inventors:

Timothy John Cassady - Hamilton OH
Norman Milstein - Montgomery OH
Richard P. Crews - Simpsonville SC

Assignee:

Henkel Corporation - Plymouth Meeting PA

International Classification:

C07C30300

US Classification:

554 92

Abstract:

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.
