A dentifrice composition containing (A) cetylpyridinium chloride, (B) hydroxyethylcellulose, and (C) an amphoteric surfactant selected from alkyldimethylaminoacetate betaine, fatty acid amide propylbetaine and 2-alkyl-N-carboxymethyl-N-hydroxyethylimidazolium betaine in which the mass ratio of (C)/(B) is 0.06 to 3, the water content is 50% by mass or less and an anionic surfactant is not practically contained. The dentifrice composition further containing (D) hydroxypropylmethylcellulose in which the mass ratio of (D)/(B) is 0.06 to 2.5, and the dentifrice composition further contained 7 to 60% by mass of an abrasive agent, 5 to 50% by mass of a thickening agent, and 0.1 to 5% by mass of a binder which is prepared as a toothpaste composition. The dentifrice composition is excellent in a bactericidal action against bacteria in the oral cavity, good in usability and useful for the prevention or treatment of a periodontal disease or dental caries. |
