Zusammenfassung:PROBLEM TO BE SOLVED: To provide a liquid composition for oral cavity which suppresses the precipitation of menthol even after low-temperature storage, provides excellent appearance stability and contains no paraoxybenzoic acid ester.SOLUTION: There are provided: a liquid composition for oral cavity which comprises (A) 0.001 to 0.15 mass% of menthol, (B) eugenol and (C) methyl salicylate without containing a paraoxybenzoic acid ester, wherein the mass ratio of (B)/(C) is 0.25 to 4 and the mass ratio of ((B)+(C))/(A) is 0.65 or more; and a method for suppressing the precipitation of menthol in the liquid composition for oral cavity by blending the components (B) and (C) in a liquid composition for oral cavity in which the component (A) is blended without blending no paraoxybenzoic acid ester and setting the mass ratio of (B)/(C) to 0.25 to 4 and the mass ratio of ((B)+(C))/(A) to 0.65 or more.SELECTED DRAWING: None 【課題】低温保存後もメントールの析出が抑制され、優れた外観安定性を与える、パラオキシ安息香酸エステルを含有しない液体口腔用組成物を提供する。【解決手段】パラオキシ安息香酸エステルを含有せず、(A)メントールを0.001〜0.15質量%含有する液体口腔用組成物であって、(B)オイゲノールと、(C)サリチル酸メチルとを含有し、かつ(B)/(C)が質量比として0.25〜4、((B)+(C))/(A)が質量比として0.65以上であることを特徴とする液体口腔用組成物、及び前記のパラオキシ安息香酸エステルを配合せず(A)成分を配合した液体口腔用組成物に(B)、(C)成分と配合し、かつ(B)/(C)を質量比として0.25〜4、((B)+(C))/(A)を質量比として0.65以上にする、前記液体口腔用組成物におけるメントールの析出抑制方法。【選択図】なし
