PROBLEM TO BE SOLVED: To provide a volatile composition which suppresses a volatilization amount of a volatile substance and increases a strength of gel of a volatile composition, and thereby reduces a difference of the volatilization amounts of the volatile substance between a wide temperature range and normal temperature and can control the volatilization amount even at high temperature.SOLUTION: A volatile composition contains at least alkyl cellulose, which has viscosity of 1 mass% aqueous solution at 20°C by Brookfield viscometer of 4,000-11,000 mPa s and storage elastic modulus G' (65°C) of 1.5 mass% aqueous solution at 65°C of 3,000-4,500 Pa, a volatile substance and a solvent.SELECTED DRAWING: None【課題】揮発性物質の揮発量を抑制し、揮発性組成物のゲルの強度を高くすることにより、広い温度範囲において常温の場合との揮発性物質の揮発量の差が少なく、高温時でも揮発量をコントロールできる揮発性組成物を提供する。【解決手段】２０℃における１質量％水溶液のＢ型粘度計による粘度が４，０００～１１，０００ｍＰａ・ｓであり、かつ６５℃おける１．５質量％水溶液の貯蔵弾性率Ｇ'(65℃)が３，０００～４,５００Ｐａであるアルキルセルロースと、揮発性物質と、溶媒とを少なくとも含む揮発性組成物を提供する。【選択図】なし
