PROBLEM TO BE SOLVED: To provide an aerosol composition giving a foamed material stable over a long time and provide an aerosol product giving a foamed material having excellent dryability, stable over a long period and changing the shape with time to give a stabilized foam forming an extremely light weight and smooth surface.SOLUTION: An aqueous stock liquid containing an anionic surfactant is emulsified with a liquefied gas to obtain an aerosol composition having an aqueous liquid/liquefied gas weight ratio of 10/90 to 60/40 and giving a foamed material having a specific gravity of 0.001-0.005 g/mL at 25°C. The aerosol composition composed of the aqueous stock liquid containing the anionic surfactant and emulsified with the liquefied gas is filled in a pressure vessel to obtain the foamable aerosol product giving an extruded and foamed material changing its shape with time and having a foam specific gravity of 0.001-0.005 g/mL at 25°C when the shape change of the foam is stopped.COPYRIGHT: (C)2003,JPO【課題】 長時間安定な発泡物を形成し得るエアゾール組成物、及び経時で発泡物の形状が変化後、停止した安定時に表面形状が滑らかで極めて軽く、乾燥性に優れ、長時間安定な発泡物を形成し得るエアゾール製品を提供する事。【解決手段】 陰イオン性界面活性剤を含有した水性原液と液化ガスとが乳化し、水性原液/液化ガス(重量比)が10/90~60/40で、25℃の泡比重が0.001~0.005g/mlの発泡物を形成するエアゾール組成物、及び界面活性剤を含有した水性原液と液化ガスとが乳化したエアゾール組成物を耐圧性容器内に充填してなり、その吐出物が経時的に形状変化する発泡物を形成し、該発泡物の形状変化が停止したときの発泡物の25℃での泡比重が0.001~0.005g/mlである発泡性エアゾール製品。
