(57) [Summary] (Modified) [Problem] Since plaque causes periodontal disease such as dental caries, gingivitis and alveolar pyorrhea, the search for an active ingredient that suppresses the formation and adhesion of plaque is needed. Various dextranases have been put to practical use because of their high plaque suppression efficiency and high safety. Among them, the present invention provides an oral composition having a more effective plaque suppression effect. SOLUTION: An oral composition comprising a polylysine and a non-cationic bactericide selected from halogenated diphenyl ether, halogenated salicylanilide, halogenated carbanilide and phenol compound. The non-cationic fungicide is triclosan and / or isopropylmethylphenol. |
