COMPOSITION FOR ORAL CAVITY

PROBLEM TO BE SOLVED: To obtain a composition for oral cavity excellent in adsorptivity on gums and flavor by including a specific pharmaceutical component, a specified alkyl ester, a specific surfactant and water, and forming the composition into a specified emulsion. SOLUTION: This composition for oral cavity comprises (A) 0.001-2 wt.% non-aqueous pharmaceutical component (e.g. vitamin E), (B) 1-100 wt.% alkyl ester (salt) of an N-α-long chain acyl basic amino acid, preferably an alkyl ester (salt) of an N-α-8-22C fatty acid acyl-L-arginine, based on the component A, (C) 100-250 wt.% nonionic surfactant (e.g. polyoxyethylene sorbitan monostearate) based on a hydrophobic component obtained by adding perfume to the component A and (D) water of 5-500 weight times as much as the total of the components A to C and the perfume, and is formed into a microemulsion having
