PROBLEM TO BE SOLVED: To provide a detergent particle aggregate excellent in shelf stability, rapidly dissolving properties and flowability, its manufacturing method, and a detergent composition containing the detergent particle aggregate. SOLUTION: The detergent particle aggregate comprises particles which are obtained by subjecting a base granule aggregate containing a water-soluble solid alkaline inorganic substance (A), and a liquid acid precursor (B) of a non-soap anionic surfactant in an amount of at least 15 wt.% based on the base granule aggregate to a step of dry neutralization, which have a flowing aid (C) on the surfaces thereof, and of which the mean particle diameter of particles having a 60 sec solubility of 90% or higher is 150-500μm. The detergent particle aggregate has a bulk density of 600 g/L or smaller. The method for manufacturing the detergent particle aggregate is characterized in that it involves specified steps. The detergent composition contains the detergent particle aggregate. COPYRIGHT: (C)2004,JPO
