PROBLEM TO BE SOLVED: To provide an oral cavity care composition which can continuously display a sterilization/disinfection effect in an oral cavity and expect improvement/prevention of periodontitis and further control/prevent halitosis.SOLUTION: In an oral cavity care composition, MGO and cyclodextrin are blended with an oral cavity care product, so that sterilization/disinfection effect originated from the MGO can be continuously displayed to expect improvement/prevention of periodontitis. Further, if a polysaccharide dialytic ferment and/or a protease are blended together with the CD, dental plaque and fur can be removed by direct action of an antimicrobial composition to an bacterium to improve periodontitis, so that control/prevention of halitosis is expected.COPYRIGHT: (C)2013,JPO&INPIT【課題】口腔内の殺菌・除菌効果が持続的に発揮され、歯周炎の改善・予防が期待でき、さらに口臭の抑制、予防が期待できる口腔ケア組成物。【解決手段】MGOとシクロデキストリンを口腔ケア用品に配合することにより、MGO由来の殺菌・除菌効果が持続的に発揮され、歯周炎の改善・予防が期待できる。さらに多糖分解酵素および/ないしはタンパク分解酵素をCDと共に配合すると、抗菌組成物が直接菌に作用する事で歯垢や舌苔を除去し、歯周病が改善されることにより、口臭の抑制・予防が期待できる口腔ケア組成物を提供できる。【選択図】なし
