High-density granulated detergent composition for clothes
 The present invention is targeted to obtain a high-density granular detergent composition for clothes washing having sufficient detergency even when the amount of dosage is small without lowering its detergency even after long-term storage by blending a non-soap anionic surfactant and a crystalline alkali metal silicate in a state of non-contact as much as possible. The high-density granular detergent composition for clothes washing, the granular detergent composition having a bulk density of from 0.7 to 1.2 g/cm.sup.3, including (A) a non-soap anionic surfactant; (B) a crystalline alkali metal silicate; and (C) a metal ion capturing agent other than Component (B). In the above detergent composition, Component (A) is added in an amount of from 10 to 50% by weight, and a total amount of Component (B) and Component (C) is from 30 to 80% by weight, and a weight ratio of Component (B) to Component (C) is (B)/(C)=1/15 to 5/1, and at least a part of (B) the crystalline alkali metal silicate is blended in builder granules, the builder granules including the crystalline alkali metal silicate, a binder and optionally an aluminosilicate. Further, (A) the non-soap anionic surfactant is contained in the builder granules in an amount of less than 10% by weight.
