PROBLEM TO BE SOLVED: To provide a dentifrice composition which improves foam performance effectively while exhibiting a high dental plaque removing ability or stain removing ability, and is also excellent in segregational stability without stringiness.SOLUTION: The invention provides a dentifrice composition containing component (I): 5 mass% or more to 40 mass% or less of granules comprising a water-insoluble powder material (A) and an inorganic binder (B) as well as component (II): 0.4 mass% or more to 3 mass% or less of a specific binder. In component (I), the average value of the ratio (SA/SS) of the area (SA) of a projected plane of the granules to the area (SS) of the circumscribed circle whose diameter is the maximum diameter (DL) in the projected plane is 0.5 or more to 0.9 or less, and the collapse strength is 1 gf/piece or more to 20 gf/piece or less.COPYRIGHT: (C)2015,JPO&INPIT【課題】高い歯垢除去能又は汚れ除去能を発揮しつつ、効果的に泡性能を高め、曳糸性もなく分離安定性にも優れる歯磨組成物に関する。【解決手段】成分(I)水不溶性粉末材料(A)、及び無機結合剤(B)を含む顆粒 5質量%以上40質量%以下、並びに成分(II)の特定の粘結剤 0.4質量%以上3質量%以下を含有し、成分(I)において、該顆粒の投影面の面積(SA)と該投影面における最大差し渡し径(DL)を直径とする外接円の面積(SS)との比(SA/SS)の平均値が0.5以上0.9以下であり、崩壊強度が1gf/個以上20gf/個以下である歯磨組成物。【選択図】図2
