<p>DETERGENT COMPOSITIONS Detergent compositions are characterised in that they 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 < IMG > and a diethylenetriamine derivative of the formula < IMG > where in each formula at least three R's represent -CH2PO3M2, with M representing hydrogen or an alkali metal and the remaining R's represent hydrogen, -CH3 or -CH2PO3M2, in which mixture the ratio by weight of the ethylenediamine derivative to the 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.</p> |
