LIQUID ORAL COMPOSITION CONTAINING ISOPROPYLMETHYLPHENOL

摘要

A liquid oral composition containing isopropylmethylphenol, which comprises: (A) an anionic surfactant selected from an sodium alkyl sulfate and an N-acylsarcosine sodium; (B) a nonionic surfactant selected from a polyoxyethylene hydrogenated castor oil having an average molar number of an ethyleneoxide unit added of 40 to 100 moles and a polyoxyethylene alkyl ether having 16 to 18 carbon atoms in the carbon chain and having an average molar number of an ethyleneoxide unit added of 10 to 40 moles; and (C) a wetting agent selected from glycerin, propylene glycol, butylene glycol and a polyethylene glycol having an average molecular weight of 190 to 630 in an amount of 5 to 15% by mass relative to the total amount of the composition, which has a moisture content of 70% by mass or more, and which contains substantially no ethanol. It becomes possible to provide a liquid oral composition having a high permeating/bactericidal effect against a periodontopathic biofilm, a good appearance stability, a reduced sticky feeling in the oral cavity during and after use, and a low irritation.
