  In the case of adding polyalkylene glycol, in order to uniformly deposit a small amount of polyalkylene glycol on the surface of the granular molded body, a method of dropping or spraying a polyalkylene glycol aqueous solution or a heated melt is preferable, and spray spraying is particularly preferable. is there. Polyalkylene glycol has binder properties, and can be dissolved in a small amount of water or melted by appropriate heating and sprayed to spray, and the amount of water that reduces the swelling and solidifying function of the granular molded body is reduced. There is no need to use. When the polyalkylene glycol is water-soluble, a polyalkylene glycol aqueous solution is used. The aqueous polyalkylene glycol solution preferably uses as little water as possible, and the polyalkylene glycol concentration in the aqueous solution is preferably 40% by mass or more. Moreover, about a water-insoluble thing, it heat-melts to moderate temperature, and a heat-melting liquid can be added. In addition, when using a polyalkylene glycol that is solid at room temperature, the above components are added in a state where the surface of the granular molded body is heated from the viewpoint of distributing the polyalkylene glycol in a substantially uniform layer form on the surface of the granular molded body. Preferably, for example, it is preferably dropped onto the granular compact immediately after drying. The temperature of the polyalkylene glycol aqueous solution or the heated melt at the time of addition is preferably 30 to 100 ° C, more preferably 30 to 80 ° C, and further preferably 30 to 60 ° C. It is preferable that the temperature of the granular compact is also in the above range.

  In the case of polyphenol addition, polyphenol alone may be added, or may be added as a mixture mixed with the polyalkylene glycol aqueous solution or the heated melt. When polyphenol alone is added, it may be added before or after the addition of the polyalkylene glycol, but it is preferable to add them simultaneously, and it is preferable to add a mixture with the polyalkylene glycol aqueous solution or the heated melt.

  It is preferable to stir the granular molded body before, during and after the addition of polyphenol and polyalkylene glycol. Thereby, polyphenol and polyalkylene glycol can be uniformly adhered to the surface. Stirring can be performed with a Fuji Paudal Malmerizer (O-230 type), a ribbon mixer or the like, and the stirring speed is preferably 30 to 1000 rpm, more preferably 50 to 300 rpm. The stirring time is appropriately selected until the polyalkylene glycol can be uniformly attached to the surface of the granular molded body, but is preferably 5 seconds to 3 minutes after the addition.

  The hydrophilic component, oil component, antibacterial agent, deodorant and the like can be used for the surface treatment of the granular molded body. Examples of the surface treatment method include a method in which the above components are added dropwise or sprayed onto the granular molded body. Moreover, a granular molded object can also be surface-treated by mixing with polyalkylene glycol aqueous solution or a heat-melting solution, and dripping or spraying. In the case of an oily component, it is preferable that the granular component is surface-treated with polyphenol and polyalkylene glycol and then, if necessary, dried and then sprayed with the oily component. By performing the surface treatment using the oil component, the releasability can be remarkably improved, and the portion swollen and solidified by urine permeation can be more easily removed. If the surface treatment is further performed with polyalkylene glycol after the surface treatment with the oil component, the effect of improving the peelability cannot be obtained. When paraffin wax and liquid paraffin are used in combination as the oil component, the paraffin wax can be dispersed in liquid paraffin and sprayed. Furthermore, the excrement disposal material can be obtained by drying and sieving as necessary.

  Excrement for cats, in which the excrement treatment material is a solid molded body made of water-swellable clay mineral, natural sand, silica gel, pulp powder, etc., and a fragrance composition, polyphenol and polyalkylene glycol are supported on the surface. In the case of a treatment material, the state of support is not particularly limited, as long as the fragrance composition, polyphenol, and polyalkylene glycol are supported on part or the entire surface of the granular molded body, but inside the water-swellable clay mineral. Should not be supported. The fragrance composition, polyphenol, and polyalkylene glycol may be in a mixed state at random or may be unevenly distributed. Among them, the polyphenol has an alkaline pH for maintaining the excellent swelling and solidifying function of the granular molded body, and is preferably mixed with the polyalkylene glycol from the viewpoint of the stability of the polyphenol. More preferably, it is unevenly distributed in the surface layer portion. It is more preferable that the fragrance composition is unevenly distributed in the surface layer portion of the excrement disposal material from the point that the deodorizing effect of the fragrance composition is more exhibited.

  The method of using the excrement disposal material is not particularly limited. For example, by placing it on a cat's toilet etc. (cat toilet sand), the cat's excrement (urine, feces) is absorbed and taken in, and the deodorizing effect is obtained. It can be demonstrated.
