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.
Claims15
A compound of the formula ##EQU3## wherein 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 substituted ammonium and n is an integer ranging from 2 to 15.
A detergent composition consisting essentially of
- 1. an organic water soluble detergent surfactant selected from the group consisting of anionic, nonionic, zwitterionic, and ampholytic detergent surfactants, and mixtures thereof;
- and
- 2. a builder compound of the formula ##EQU4## wherein R is a hydrocarbon radical having from 12 to 22 carbon atoms, X is sulfur, sulfinyl, or sulfonyl, M is hydrogen, a monovalent metal, ammonium or substituted ammonium and n is an integer ranging from 2 to 15.
