<p>Disclosed is an emulsion-type liquid composition for the oral cavity, which comprises (A) a liquid composition for the oral cavity that contains isopropyl methyl phenol and is substantially ethanol-free, (B) polyoxyethylene hydrogenated castor oil having an E.O. of 40 to 100 moles, (C) (C-1) a decaglycerin monofatty acid ester and (C-2) a trifatty acid glyceryl, and (D) a polyhydric alcohol selected from glycerin, propylene glycol and polyethylene glycol having an average molecular weight of 190 to 630, wherein the [(B)+(C-1)]/[(C-2)] ratio is 0.77 to 1.87 by mass, the component (D) is contained in an amount of 5 to 15 mass%, and glycerin is contained in an amount of 0.003 mass% or more. The emulsion-type liquid composition has a high infiltration/sterilization effect on a periodontopathic biofilm, enables high accumulation of isopropyl methyl phenol in the oral cavity, and has good appearance stability and mild irritating properties. Also disclosed is a process for producing the composition, which comprises mixing the components (A), (B) and (D) with one another and adding the component (C) in the form of an emulsion to the resulting mixture.</p> |
