The present invention has as its object the provision of an aerosol product for forming a gel composition. The aerosol product has high storage stability and can form a desired gel composition easily and stably.The aerosol product for forming a gel composition of the present invention has a double-structure container including a propellant filling space and two liquid concentrate filling spaces and having a discharging mechanism for simultaneously discharging the contents filled in the two liquid concentrate filling spaces. The propellant filling space is filled with a propellant composed of a compressed gas, a first liquid concentrate filling space is filled with a first liquid concentrate composition containing water and a water-soluble alginic acid salt, and a second liquid concentrate filling space contains a second liquid concentrate composition containing water and a dissociative calcium salt. The first liquid concentrate composition and the second liquid concentrate composition are mixed to form a gel composition.
