PROBLEM TO BE SOLVED: To provide a glucanase enzyme-containing dentifrice composition in which the residence time of the glucanase enzyme in an oral cavity is increased to enhance plaque removing ability, and which is excellent in enzyme stability in a dentifrice composition, excellent in formability of a dentifrice, excellent in a foaming property during brushing of teeth and resistance against liquid separation with time, and also excellent in an anticaries effect.SOLUTION: The glucanase enzyme-containing dentifrice composition includes (A) 0.02-0.2 mass% of a cationic polymer, (B) 0.4-1.6 mass% of a fatty acid amide propylbetaine with a 12C-14C fatty acid, and (C) 0.5-3 mass% of at least one selected from hydroxyethylcellulose, hydroxypropyl methyl cellulose, and methyl cellulose. The mass ratio of the ingredient (C)/ingredient (A) is 10-100. In addition, (D) 0.1-2 mass% of a condensed phosphate is added thereto.COPYRIGHT: (C)2011,JPO&INPIT【課題】グルカナーゼ酵素配合の歯磨組成物において、口腔内へのグルカナーゼ酵素の滞留性を高めることで歯垢除去力が向上し、歯磨組成中での酵素の安定性に優れると共に、歯磨製剤の成形性、歯磨き時の泡立ち及び経時での液分離安定性に優れ、ムシ歯予防効果に優れた歯磨組成物を提供する。【解決手段】グルカナーゼ酵素配合の歯磨組成物に、(A)カチオン性ポリマーを0.02~0.2質量%、(B)脂肪酸の炭素数が12~14の脂肪酸アミドプロピルベタインを0.4~1.6質量%、(C)ヒドロキシエチルセルロース、ヒドロキシプロピルメチルセルロース、メチルセルロースから選ばれる少なくとも1種を0.5~3質量%配合し、かつ(C)成分/(A)成分の質量比を10~100とする。更に、(D)縮合リン酸塩を0.1~2質量%配合する。【選択図】なし
