PROBLEM TO BE SOLVED: To provide a dentifrice composition which has moderate polishing ability, high cleaning ability, reduced bitter taste, and good feel of use.SOLUTION: The dentifrice composition includes (A) a synthesized amorphous aluminum-bonded silicate in which the amount of aluminum is in the range of 0.5-7.5 mass% to SiO2 as Al2O3 and the amount of OH groups is 2.0-3.5 mass% to SiO2 and (B) l-menthol. The dentifrice composition barely has injurious property to the teeth, moderate polishing ability and high cleaning ability without damaging the teeth, reduced bitter taste associated with the synthesized amorphous aluminum-bonded silicate of a silica dentifrice, and good feel of use.COPYRIGHT: (C)2011,JPO&INPIT【解決手段】(A)アルミニウムがAl2O3としてSiO2に対し0.5~7.5質量%の範囲で、かつOH基量がSiO2に対し2.0~3.5質量%である合成無定形アルミニウム結合ケイ酸塩、及び(B)l-メントールを含有してなることを特徴とする歯磨剤組成物。【効果】本発明の歯磨剤組成物は、歯牙に対する為害性がほとんどなく、歯牙を損傷させない適度な研磨性と高い清掃性を有し、かつシリカ系研磨剤の合成無定形アルミニウム結合ケイ酸塩由来の渋味が軽減され良好な使用感を有する。【選択図】なし
