PROBLEM TO BE SOLVED: To provide a method for producing a dentifrice by which a mixing time is shortened.SOLUTION: The method for producing the dentifrice includes the following steps 1 to 3: step 1 for preparing a powder mixture by mixing a binder powder with 0.1-4.0 pts.mass of the powder component selected from the group consisting of a humectant, an antiseptic agent and a sweetener, having 100-2,000 &mum average particle diameter and 0.50-1.20 g/ml bulk density based on 1 pt.mass of the binder powder step 2 for preparing a mixed liquid by feeding the powder mixture prepared at the step 1 to a continuous mixer by using a rotary powder feeder having 0-1.0 mm clearance between a rotary part and a fixed part, and mixing the powder mixture with water and the humectant under a reduced pressure and step 3 for producing the dentifrice by feeding the mixed liquid obtained at the step 2 to a batch-type mixer, and mixing the mixed liquid with an abrasive, a foaming agent, a perfume and the water.COPYRIGHT: (C)2009,JPO&INPIT【課題】混合時間が短縮された歯磨剤の製造方法を提供する。【解決手段】下記工程1~3を含むことを特徴とする歯磨剤の製造方法。工程1:粘結剤粉体と、該粘結剤粉体1質量部あたり0.1~4.0質量部の、湿潤剤、防腐剤及び甘味剤からなる群より選ばれ、平均粒子径が100~2000μmであり、嵩密度が0.50~1.20g/mlである粉体成分とを混合して粉体混合物を調製する工程、工程2:回転部と固定部とのクリアランスが0~1.0mmである回転式粉体供給機を用いて、工程1で調製した粉体混合物を連続式混合機へ供給し、水及び湿潤剤と減圧下で混合して混合液を調製する工程、及び工程3:工程2で得られた混合液をバッチ式混合機へ供給し、研磨剤、発泡剤、香料及び水と混合して歯磨剤を製造する工程。【選択図】なし
