<p>Disclosed is a composition for the oral cavity containing (A) an ascorbic acid phosphate ester or a salt thereof, (B) vitamin E or a derivative thereof, (C) a surfactant selected from among POE-hardened castor oils having an average mole number of added EO units of 10-60, POE alkyl ethers having a C14-18 alkyl group and an average mole number of added EO units of 5-8, and alkyl glucosides having a C10-14 alkyl group, and (D) a nonionic bactericide, wherein the total amount of (A), (B) and (D) is 0.2-1.5% by mass and the mass ratio of (C)/((B) + (D)) is 8-20. Also disclosed is a composition for the oral cavity containing the above-described components (A)-(C) and (E) a cationic bactericide, wherein the total amount of (A), (B) and (E) is 0.2-1.3% by mass and the mass ratio of (C)/((B) + (E)) is 8-18. An ascorbic acid phosphate ester or a salt thereof, vitamin E or a derivative thereof, and a bactericide are stably and effectively blended in the compositions for the oral cavity. Consequently, the compositions for the oral cavity exhibit an excellent preventive or ameliorating effect on periodontal diseases, and have excellent long-term storage stability.</p> |
