Abstract
New monoesters derived from ethoxylated higher alcohols and thiodisuccinic acid having the formula: ##EQU1## in which R is a hydrocarbon having from 12 to 22 carbon atoms, X is sulfur, sulfinyl, or sulfonyl, M is hydrogen, a monovalent metal, ammonium or a salt of ammonium, and n is an integer ranging from 2 to 15, are useful as detergent builders and are particularly suitable for hard water detergents. In preferred esters, R is alkyl or alkenyl, X is sulfur, M is hydrogen or sodium, and n is an integer ranging from 3 to 7.
