- the base granules obtained by spray drying (hereinafter referred to as slurry in the present invention) have an extremely low oil absorption compared to the oil absorption capacity (expected value) estimated from the specific surface area of the base and the pore volume in the base granules. Only the ability was expressed. Then, the present inventors examined the cause, and found that the water-soluble polymer component, which is a component for securing the particle strength of the base granule, tends to be unevenly distributed on the surface of the base granule and its vicinity in the spray drying process. As a result, it was clarified that an amorphous film composed of a water-soluble polymer and a water-soluble salt was formed on the surface of the base granules.
- the present inventors have found that such base granules have a surface state that is unsuitable for supporting a surfactant, which is an oily substance, and for absorbing oil, so that the base granules can fully exhibit the inherent oil absorbing ability of the base granules. I thought he didn't.
- the present inventor has further studied the process of spray drying and the base granules. As a result, it was found that a certain substance has the ability to inhibit the formation of a film.
- the base granule group of the present invention is an aggregate of base granules, and has a surfactant content of 0 to 10% by weight.
- a slurry containing a surfactant is spray-dried to produce base granules, a film tends to be formed on the surface of the obtained base granules. May decrease.

- a film-forming inhibitor is present on the surface of the base granules and / or in the vicinity thereof in terms of the surfactant loading and oil absorption.
- the presence of a film formation inhibitor on and / or in the vicinity of the base granules can be determined by observing the base granules by scanning electron microscopy (SEM) or energy dispersive X-ray spectroscopy (EDS). You can know.
- SEM scanning electron microscopy
- EDS energy dispersive X-ray spectroscopy
- the presence of the film-forming inhibitor as crystals means that a peak derived from the film-forming inhibitor is detected when powder X-ray diffraction analysis of the base granules is performed.
- Sodium carbonate, sodium sulfate, and the like which are generally used as water-soluble salts to be combined with detergents, are easily compatible with the water-soluble polymer and tend to partially become amorphous.
- the halogenated alkali metal salt since the halogenated alkali metal salt has high crystallinity, the halogenated alkali metal salt is crystallized alone and usually exists as crystals in the base granules in the present invention. For this reason, it is preferable to use an alkali metal halide as a film formation inhibitor.
