Provided are the following: a novel aerosol agent that is a substitute for conventional aerosol agents and has excellent emulsion stability of an emulsion composition; and an emulsion composition for aerosol preparation. The emulsion composition for aerosol preparation contains an oil phase, an aqueous phase, and either vesicles formed by an amphipathic substance that spontaneously forms vesicles or particles of a condensation polymer having hydroxyl groups. The oil phase preferably contains a polymer compound having hydrophilic groups and hydrophobic groups. Moreover, the aerosol agent contains a starting liquid formed from such emulsion composition and a propellant. The aerosol agent is ideal for application to a solid surface. |
