To provide an aerosol product capable of forming a foam that gradually foams after being discharged, shows good foam formation even in extremely low temperature environments, and has excellent volume.SOLUTION: The aerosol product comprises: a container; an inner container provided inside the container and filled with a post-foaming composition; and a discharge mechanism provided in the container and configured to discharge the post-foaming composition. In the container, a space formed between the inner container and a partition wall of the container is filled with a propellant. The post-foaming composition comprises water and a concentrate composition comprising a surfactant, and monochlorotetrafluoropropene. The monochlorotetrafluoropropene is at least one selected from (Z)-1-chloro-2,3,3,3-tetrafluoropropene (HCFO-1224 yd(Z)) and (E)-1-chloro-2,3,3, 3-tetrafluoropropene (HCFO-1224 yd(E)).SELECTED DRAWING: None 【課題】吐出後に徐々に発泡し、極低温環境であっても良好な泡沫形成性を示し、ボリュームに優れるフォームを形成できるエアゾール製品。【解決手段】容器、該容器の内部に設けられ、後発泡性組成物が充填された内容器、及び該容器に備えられ、該後発泡性組成物を吐出させる吐出機構を有するエアゾール製品であって、該容器の内部において該内容器と該容器の隔壁との間に形成される空間に噴射剤が充填されてなり、該後発泡性組成物が、水、及び界面活性剤を含む原液組成物、並びにモノクロロテトラフルオロプロペンを含み、該モノクロロテトラフルオロプロペンが、（Ｚ）－１－クロロ－２，３，３，３－テトラフルオロプロペン（ＨＣＦＯ－１２２４ｙｄ（Ｚ））及び（Ｅ）－１－クロロ－２，３，３，３－テトラフルオロプロペン（ＨＣＦＯ－１２２４ｙｄ（Ｅ））からなる群から選択される少なくとも一である、エアゾール製品。【選択図】なし
