PROBLEM TO BE SOLVED: To provide an expandable aerosol product that is more likely to exert its effect to an object by: causing defoaming as if to pop foams after the aerosol product forms its foams on the object or after the aerosol product adheres to the object in a bubble and then performing chemical and physical actions of a medical agent.SOLUTION: The expandable aerosol product contains: an aqueous stock solution comprising a foaming agent, a water-soluble solvent, water and oil content and an aerosol composition comprising liquefied gas. The expandable aerosol product forms the foams that are defoamed as if to pop the foams after the aerosol product forms its foams on the object or after the aerosol product adheres to the object in the bubble.COPYRIGHT: (C)2012,JPO&INPIT【課題】対象物上で発泡後あるいは泡状に付着した後で、泡が弾けるように破泡し、薬剤による化学的な作用だけでなく、物理的な作用を加えて対象物に効果を発揮しやすい発泡性エアゾール製品を提供すること。【解決手段】起泡剤、水溶性溶剤、水、油分を含有する水性原液と、液化ガスとからなるエアゾール組成物を含有する発泡性エアゾール製品であって、対象物上で発泡後あるいは泡状に付着した後で、弾けるように破泡するフォームを形成する発泡性エアゾール製品である。【選択図】なし
