PROBLEM TO BE SOLVED: To provide a method for stably keeping viscosity of a composition which contains a cellulose-based thickening agent and is applied to a mucous membrane, and to provide the composition of which the viscosity is stably kept. SOLUTION: This composition contains the cellulose-based thickening agent, a nonoinic surfactant, and a specified plant oil, so that the viscosity of the composition is prevented from being decreased, because the plant oil is contained therein. Thus, the viscosity of the composition is stably kept for a long period. COPYRIGHT: (C)2005,JPO&NCIPI
