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.sub.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.
本文披露了烷氧基琥珀酸、烷氧基羟基琥珀酸、烷硫基琥珀酸、烷硫基羟基琥珀酸以及烷硫基琥珀酸和烷硫基羟基琥珀酸的亚砜和砜衍生物的新型建筑盐。新的建筑盐化合物可以通常表示如下:其中Z选自包括O、S、SO和SO.sub.2的组;X为H或OH;R为含有6至30个碳原子的烷基基团,M选自包括碱金属阳离子、铵和取代铵的组。这些新的建筑盐化合物可以替代含有磷或氮的现有建筑盐,而不会损害并且在某些情况下可以提高这些洗涤剂配方的效率。
