A builder system for detergent compositions comprises 25 to 97% by weight of an aluminosilicate cation-exchange material such as Zeolite A and 3 to 75% by weight, in total, of an organic precipitant builder having a polyvalent anion, for example, an alkyl or alkenyl malonate or succinate, and an organic sequestrant such as a nitrilotriacetate. The ratio of precipitant to sequestrant is 10:1 to 1:10. The builder mix is advantageously used in detergent compositions containing less than 10% inorganic phosphate, and gives good results in zero-phosphate compositions.
