Abstract: A process for producing nonionic detergent granules having a bulk density of from 0.6 to 1.2 g/ml is disclosed, which comprises the following steps (1) to (3): (1) mixing a detergent material comprising a nonionic surfactant; (2) granulating a mixture obtained in said step (1) by agitating in an agitating mixer provided at the center position thereof with a rotation shaft having an agitation impeller with a clearance between the agitation impeller and an inner wall of the mixer, wherein the agitation impeller agitates the mixture to form an adhesion layer of said mixture on said inner wall of said mixer so as to increase a bulk density of granules of the mixture; and (3) mixing the granules obtained in said step (2) with fine particles to thereby coat the surface of the granules with the fine particles. The nonionic detergent granules containing a nonionic surfactant in a high content and having high bulk density and excellent powder fluidity and non-caking property can be produced in the process of the present invention with less suffering from restriction in the composition.
