Abstract

Softening agent esp. for washing-up solns. comprising an alkylenediaminomethylenephosphonic acid, with an alkyl side group, of formula:- (R = CH3) and a poly(alkyleneamino)-methylenephosphonic acid. The agent prevents granular deposits caused by hard water. The presence of the alkyl side group in the acid increases its solubility.
