PROBLEM TO BE SOLVED: To provide an aerosol composition which is convenient even for unskilled users to handle and easy for every user to use, convenient to carry and user-friendly, enables fine spraying and retains good conditions of fine particles consistently from the start of spraying to using up, and an aerosol type spray device packed with the composition. SOLUTION: A molding release agent is formulated as an aerosol composition, and the composition is packed in an aerosol container. The aerosol container is filled with a liquid phase comprising liquefied dimethyl ether and a water-soluble release agent and a gas phase comprising a compressed gas. With the ratio of the gas phase set to be higher than that of the liquid phase, the composition can be sprayed uniformly until the water-soluble release agent is used up even when the amount of the liquefied dimethyl ether is so small as to impair the stability of the water-soluble release agent. A valve of a vapor tap orifice structure is arranged in the aerosol container to realize atomized spraying. COPYRIGHT: (C)2008,JPO&INPIT
