The present invention provides a liquid oral composition that improves the adsorption effect of cetylpyridinium chloride having bactericidal activity against oral bacteria on the tooth surface while maintaining the solution stability of the preparation. The blending ratio of the nonionic surfactant to the water-insoluble component is 0, containing cetylpyridinium chloride, a water-insoluble component and a nonionic surfactant and further containing 0 to 10% by weight of ethanol. A transparent liquid oral composition that is .55 to 3.6. [Selection figure] None |
