Abstract
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 <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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
133 words
A detergent composition comprising a surfactant, other conventional additives, and on a dry weight basis, from 4 to 15% of a water-insoluble aluminosilicate and from 0.5 to 2.5% of an aminopoly(methylenephosphonate) component which is a mixture of an ethylenediamine derivative of the formula ##STR5## and a diethylenetriamine derivative of the formula ##STR6## wherein, in each formula, R is selected from H, --CH 2 PO 3 M 2 and --CH 3 wherein M is selected from hydrogen and alkali metal, provided that at least 80% of the Rs are --CH 2 PO 3 M 2 and further provided that the weight ratio of ethylenediamine derivative to diethylenetriamine derivative is about 1.2, and the combined weight of the aluminosilicate material and the aminopoly(methylenephosphonate) component is at least 5% of the dry weight of the composition.
Claim 2
Dependent Claim
133 words
A detergent composition comprising a surfactant, other conventional additives, and on a dry weight basis, from 4 to 15% of a water-insoluble aluminosilicate and from 0.5 to 2.5% of an aminopoly(methylenephosphonate) component which is a mixture of an ethylenediamine derivative of the formula ##STR5## and a diethylenetriamine derivative of the formula ##STR6## wherein, in each formula, R is selected from H, --CH 2 PO 3 M 2 and --CH 3 wherein M is selected from hydrogen and alkali metal, provided that at least 80% of the Rs are --CH 2 PO 3 M 2 and further provided that the weight ratio of ethylenediamine derivative to diethylenetriamine derivative is about 1.2, and the combined weight of the aluminosilicate material and the aminopoly(methylenephosphonate) component is at least 5% of the dry weight of the composition.
