PROBLEM TO BE SOLVED: To provide compositions for oral care that can complement reduced salivary secretion levels, the composition further having a function that can inhibit the proliferation of oral bacteria.SOLUTION: The present invention provides a composition for oral care containing a substance effective in oral hygiene (a substance with antimicrobial action and bactericidal action) and a substance expressing viscosity (a substance with thickening action, such as a thickener), wherein the viscosity can be controlled by the amount of added water. The invention also provides a composition for oral care that can control remaining levels and/or sustained-release levels of the substance effective in oral hygiene in the oral cavity by the amount of added water. The invention also provides a composition for oral care in which salivary does not affect the change of viscosity. The substance which expresses viscosity has water-retention effect and includes xanthan gum. The substances effective in oral hygiene are plant polyphenol and/or bacteriocin.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2016,JPO&INPIT【課題】唾液の分泌量の減少分を補完でき、さらに口腔内細菌の増殖を抑制できる機能を持った口腔ケア用組成物を提供する。【解決手段】口腔衛生に有効な物質(抗菌作用、殺菌作用を持つ物質)と粘性を発現する物質(増粘剤等の増粘作用を持つ物質)とを含有し、粘性を加水量により調整できる口腔ケア用組成物。口腔衛生に有効な物質の口腔内における滞留量及び/又は除放量を加水量により調整できる口腔ケア用組成物。唾液の影響により粘性が変化しない口腔ケア用組成物。粘性を発現する物質は保水効果を有し、キサンタンガムを含むものである。口腔衛生に有効な物質は植物ポリフェノール及び/又はバクテリオシンである。【選択図】図1
