Abstract: PROBLEM TO BE SOLVED: To provide a phosphor dispersion liquid composition for adding to powder detergent, containing hardly water-soluble phosphor difficult to be uniformly distributed in detergent particles and having excellent aging stability (low precipitation/separation tendency), a method for producing the composition, and a powder detergent composition produced by adding the dispersion composition to a base detergent particle group and having excellent dyeing capacity to clothes.
SOLUTION: The phosphor dispersion liquid composition for adding to powder detergent is a solution of a water-soluble polymer having an average molecular weight of ≥2,000 and containing dispersed hardly water-soluble phosphor. The minimum precipitation distance of the undissolved phosphor is ≤40mm after leaving at rest at 80°C for 4 days. The method for producing the dispersion composition comprises the dispersion of the hardly water-soluble phosphor in the solution of the water-soluble polymer by a dispersion machine and the adjustment of the minimum precipitation distance of the undissolved phosphor to ≤40mm after leaving at rest at 80°C for 4 days. The powder detergent composition is produced by adding the phosphor dispersion liquid composition to a base detergent particle group.

SOLUTION: This composition comprises high-bulk-density detergent particles containing a surfactant and having a 95% dissolution time of 90 s or below as measured at 10 deg.C by the conductivity method and a bulk density of 500 g/l or above, bleach-accelerator-containing particles having a 95% dissolution time of 120-480 s as measured in the manner identical with the above, and particles having the ability to liberate H2O2 in an aqueous solution. It is desirable that the high-bulk-density detergent particles are ones having a mean particle diameter of 150-600 μm and prepared by infiltrating a surfactant into base granules containing a difficultly water-soluble inorganic material and a water-soluble component selected from among water-soluble polymers and water-soluble salts or ones having a such a size that the mean particle diameter is 150-500 μm, and particles with diameters of 710 μm or above and particles with diameters of below 125 μm account for at most 10 wt.% of the entire detergent particles, respectively.
