Abstract

Abstract There are disclosed herein novel builder salts of alkyloxysuccinic acids, alkyloxyhydroxysuccinic acids, alkylthiosuccinic acids, alkylthiohydroxysuccinic acids, and the sulfoxide and sulfone derivatives of the alkylthiosuccinic and alkylthiohydroxysuccinic acids. The new builder compounds can be generally represented as follows: ##STR1## wherein Z is selected from the group consisting of O, S, SO and SO 2 ; X is H or OH; R is an alkyl radical containing from 6 to 30 carbon atoms and M is selected from the group consisting of alkali metal cations, ammonium and substituted ammonium. These new builder compounds can be substituted in detergent compositions for existing builders containing phosphorous or nitrogen without impairing and in some cases improving the efficiency of such detergent compositions.
