Abstract (en)
A detergent composition contains as builder a combination of an aluminosilicate cation-exchange material, for example, Zeolite A, with an organic precipitant builder having the formula I <CHEM> wherein: R1 is C10-C24 alkyl or alkenyl, or an arylalkyl or alkylaryl group of equivalent chain length; X is CH, CR2, N or CON; R2 is C1-C3 alkyl; Y is hydrogen or a solubilising cation: n and m, which may be the same or different, are O or integers from 1 to 4; and Z is COOY or SO3Y. Preferred organic precipitant builders are the alkyl or alkenyl malonates and succinates. The inorganic phosphate content is desirably less than 10% by weight, and zerophosphate compositions are preferred.
