Method for producing detergent particle



PROBLEM TO BE SOLVED: To provide a method for producing low bulk density detergent particles having a good water infiltration into the particles on its use, excellent in easy dissolution property, especially suitable for hand washing, having a good particle flowing property, and also excellent in caking resistance in the preservation of the product, at a low cost, low bulk density detergent particles having such characteristics and a detergent composition containing the detergent particles. SOLUTION: The detergent particles are produced by performing a first granulation of powdery or granular solid detergent raw materials with a liquid detergent raw material, crushing the obtained first granulated material, then passing through a process of a second granulation of the crushed first granulated material with a liquid binder in a fluidized bed to obtain as having ≤600 g/L bulk density. Also the detergent particles contains a surfactant, and has a structure of cross-linking a powdery material with the liquid binder, and having ≥700 g/L bulk density and ≤200 μm mean particle diameter, and containing ≤5 wt. % content of particles having ≥1,000 mμ particle diameter.
