The method for producing a surfactant-supporting granule group of the present invention comprises a container rotary granulator comprising a powder raw material containing an inorganic alkali having an oil absorption capacity of 0.4 mL / g or more and a binder that is solid at room temperature or its precursor binder. And a step of supplying the binder or its precursor binder using a multi-fluid nozzle at a temperature equal to or higher than its melting point. By this production method, a surfactant-supporting granule group having a bulk density of 800 g / L or less can be obtained. One of the features of the present invention is that since the granule group obtained by such a production method has a small amount of water, it can be used as it is as a raw material for the detergent particle group without performing a drying operation such as spray drying.

The surfactant-supporting granule group in the present invention is presumed to have a structure in which powder raw materials having an oil absorption capacity of 0.4 mL / g or more are gradually aggregated by a solid binder or a precursor thereof at room temperature. Therefore, it has two supporting sites: (1) a large gap between powder raw materials, and (2) a small gap in the powder raw material (for example, a gap of 10 μm or less). Of these, both (1) and (2) have a significant effect on the loading capacity and loading force, and (1) has a significant effect on the loading speed. Surfactants with the desired loading capacity can be adjusted by adjusting these two loading sites. A group of supporting granules can be obtained.
