    Abstract: The powder detergent composition for clothes washing having a bulk density of 0.50 g/mL or more, including 5 % by weight or more of a crystalline sodium silicate represented by the general formula (1): Na2O . xSiO2 . yH2O. In the formula, x and y each stands for a molar number, and x is from 1.5 to 2.2, and y is from 0 to 5. The crystalline sodium silicate has an average particle size of from 1 to 100 mu m and comprises crystalline phases of a delta -phase and an alpha -phase, and at least one of a beta -phase and an NS-phase, wherein the compositional weight ratios of the alpha -phase, the beta -phase, and the delta -phase satisfy all of the following relationships: 0.05

    Abstract: 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 , 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.

    Abstract: A detergent composition for clothing comprising the following components (I) and (II): (I) a surfactant component comprising (A) a sulfonate anionic surfactant and (B) at least either a nonionic surfactant or a sulfate anionic surfactant at a (B) to (A) weight ratio of 1/10 to 2/1, and (II) a component comprising (C) an alkali metal silicate and (D) a sequestering agent other than the component (C) at a (C) to (D) weight ratio of 1/15 to 5/1, in total amounts of the components (I) and (II) of 20 to 50 % by weight and 30 to 80 % by weight, respectively, and having a bulk density of 0.6 g/cc or above; and a process for washing clothing with this detergent composition. The composition makes it possible to remarkably reduce the standard use level of detergents as compared with those of ordinary compact detergent compositions for clothing.
