Abstract: Aminomethylenephosphonate-coated granules of substantially water-insoluble silicate having improved stability in the presence of peroxygen compounds. Such coatings can comprise alkali metal aminomethylenephosphonate of the formula: ##STR1## where each R is H, CH.sub.2 PO.sub.3 H.sub.2 or CH.sub.2 PO.sub.3 HM or CH.sub.2 PO.sub.3 M.sub.2 ; where M is an alkali metal; and n is 0 or an integer, preferably an integer of from 1 to 4. The coatings are substantially free of peroxygen compounds and peroxy compound precursors.

Abstract: 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 ##STR1## and a diethylenetriamine derivative of the formula ##STR2## wherein, in each formula, R is selected from H, --CH.sub.2 PO.sub.3 M.sub.2 and --CH.sub.3 wherein M is selected from hydrogen and alkali metal, provided that at least 3 Rs are --CH.sub.2 PO.sub.3 M.sub.2 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.
