PROBLEM TO BE SOLVED: To provide a composition for oral cavity containing sodium fluoride and aluminum lactate and having pH of the composition adjusted to a neutral range (pH 6.0-8.0), exhibiting high fluoride deposition promoting effect on dentin, free from formation of precipitate even in a neutral pH range, having high storage stability with time and excellent usability and, accordingly, expectable to have high caries preventing or suppressing effect.SOLUTION: The composition for oral cavity includes (A) sodium fluoride and (B) aluminum lactate, has a pH of the composition of 6.0-8.0, and is produced by compounding 0.02-0.5 mass% of sodium fluoride (A), 0.05-1.0 mass% of aluminum lactate (B) and 0.008-0.5 mass% of cationized cellulose (C), and setting the mass ratio of (B)/(A) to 0.3-10 and the mass ratio of (C)/((A)+(B)) to 0.08-0.8.COPYRIGHT: (C)2011,JPO&INPIT【課題】フッ化ナトリウムと乳酸アルミニウムを含有し、かつ組成物のpHを中性領域(pH6.0~8.0)に調整した口腔用組成物において、歯質への高いフッ化物沈着促進効果が発揮され、かつpHが中性領域でも沈殿を発生せず、経時での保存安定性も高く、使用感に優れ、その結果、高いう蝕予防又は抑制効果が期待できる口腔用組成物を提供する。【解決手段】(A)フッ化ナトリウムと(B)乳酸アルミニウムとを含有し、組成物のpHが6.0~8.0である口腔用組成物であって、(A)フッ化ナトリウムを0.02~0.5質量%、(B)乳酸アルミニウムを0.05~1.0質量%、及び(C)カチオン化セルロースを0.008~0.5質量%配合し、かつ(B)成分/(A)成分の質量比を0.3~10、(C)成分/[(A)成分+(B)成分]の質量比を0.08~0.8としたことを特徴とする口腔用組成物。【選択図】なし
