<P>PROBLEM TO BE SOLVED: To provide a powder detergent composition, capable of reducing generation of a water-insoluble content formed by integrating alkali metal silicate and aluminosilicate in a powder detergent composition containing the alkali metal silicate and the aluminosilicate. <P>SOLUTION: The powder detergent composition contains: an alkali metal silicate particle (A) obtained by forming an alkali metal silicate (a1) with an average particle size from 1 to 1,000 μm and a surface treatment agent (a2) that is present on the surface thereof into composite; and aluminosilicate (B) with an average particle size from 0.1-50 μm. The surface treatment agent (a2) is a non-ionic organic compound and/or a cationic organic compound, having a melting point from 45-90°C, a molecular weight from 200-700, moisture permeability from 0-2%, and solubility of 0.5 g or less with respect to 100 g of water at 20°C. <P>COPYRIGHT: (C)2012,JPO&INPIT |
