PURPOSE:To obtain a composition for oral cavity application having especially high bactericidal power, by using an oral cavity composition containing hinokitiol and chlorhexidines in combination with a carboxylic acid-type ampholytic surfactant, thereby improving the bactericidal effect. CONSTITUTION:A composition for oral cavity application having strong bactericidal effect and exhibiting sufficient bactericidal effect even in a small amount can be produced by compounding (A) a carboxylic acid-type ampholytic surfactant, preferably betaine-type, imidazoline-type or imidazolinebetaine-type, especially betaine-type ampholytic surfactant in an amount of 0.1-8wt.%, especially 0.5-3wt.% (based on the whole composition) to an oral cavity composition such as tooth paste or tooth powder containing (B) hinokitiol and (C) chlorhexidines such as chlorhexidine gluconate and chlorhexidine hydrochloride. The amounts of the components B and C are preferably 0.001-1wt.% each based on the whole composition. |
