PROBLEM TO BE SOLVED: To provide a method for efficiently producing granules that have a moderate pore volume and are suitable as a dentifrice.SOLUTION: A method for producing dentifrice granules has a step of mixing a water-insoluble powder material and an organic binder heated to the temperature equal to or higher than the melting point, with a vessel rotary mixer. The melting point of the organic binder is 25°C or more, and in the step, a multi-fluid nozzle is used to supply the water-insoluble powder material with the organic binder.SELECTED DRAWING: NoneCOPYRIGHT: (C)2020,JPO&INPIT【課題】適度な細孔容積を有し、歯磨剤用として好適な顆粒を効率よく製造する方法を提供すること。【解決手段】水不溶性粉末材料及び融点以上の温度に加熱した有機結合剤を、容器回転型混合機を用いて混合する工程を有し、該有機結合剤の融点が２５℃以上であり、該工程において、多流体ノズルを用いて、該水不溶性粉末材料に有機結合剤を供給する、歯磨剤用顆粒の製造方法。【選択図】なし
