PROBLEM TO BE SOLVED: To provide a liquid composition for oral cavities which, while improving an adsorption effect of cetylpyridium chloride having sterilization activity against bacteria in the oral cavity on a teeth surface, retains also solution stability of a formulation.SOLUTION: The transparent liquid composition for oral cavities includes cetylpyridium chloride, a water-insoluble component and a nonionic surfactant together with 0-10 wt.% of ethanol. The formulation ratio of the nonionic surfactant to the water-insoluble component is 0.55-3.6.COPYRIGHT: (C)2010,JPO&INPIT【課題】口腔内細菌に対する殺菌活性を有する塩化セチルピリジニウムの歯牙表面への吸着効果を向上させながら、さらに製剤上の溶液安定性を保持させた液体口腔用組成物の提供。【解決手段】塩化セチルピリジニウム、非水溶性成分、非イオン性界面活性剤を含有し、さらにエタノールを0~10重量%含有する、非水溶性成分に対する非イオン性界面活性剤の配合比率が0.55~3.6である透明な液体口腔用組成物。【選択図】なし
