DIAMINOALKYL DI(SULPHOSUCCINATES) AND DETERGENT COMPOSITIONS CONTAINING THEM
Diaminoalkyl di(sulphosuccinate) (DDSS) compounds of formula (I) wherein M is an alkali metal or an alkaline earth metal or a mixture; and R1 is CH2 or CHOH and is optionally present, and when R1 is present R2 is hydrogen, and when R1 is absent R2 is methyl or hydrogen, are novel materials which are highly effective chelants of di- and polyvalent metal ions and are useful as builders in detergent compositions.
