[origin: WO9203525A1] Particulate laundry detergent compositions are disclosed incorporating 5 % to 50 % of a surfactant, from 10 % to 95 % of a three-component non-phosphorus builder system comprising a mixture of a sodium aluminosilicate zeolite, a water-soluble monomeric or oligomeric carboxylate chelating agent and a crystalline layered sodium silicate, and from 0 % to 40 % of non-surfactant, non-builder detergent ingredients. The crystalline layered silicate is of composition NaMSixO2x+1.yH2O where M is sodium or hydrogen, x is a number from 1.9 to 4 and y is a number from 0 to 20. Preferably M is sodium, x is 2 and y is O.
