Detergent compositions are disclosed which contain on a dry weight basis, from 1 to 40% of a water-insoluble aluminosilicate and from 0.5 to 5% of a aminopoly(methylenephosphonate) component which is a mixture of an ethylenediamine derivative of the formula <IMAGE> and a diethylenetriamine derivative of the formula <IMAGE> wherein, in each formula, R is selected from H, -CH2PO3M2 and -CH3 wherein M is selected from hydrogen and alkali metal, provided that at least 3 Rs are -CH2PO3M2 and further provided that the weight ratio of ethylenediamine derivative to diethylenetriamine derivative is from 3:1 to 1:5, and the combined weight of the aluminosilicate material and the aminopoly(methylenephosphonate) component is at least 5% of the dry weight of the composition. |
