Abstract
A foam forming aerosol product including a double structure container having a propellant filling space, two liquid concentrate filling spaces, and a discharging mechanism for simultaneously discharging contents filled in the two liquid concentrate filling spaces. The propellant filling space is filled with a propellant containing a compressed gas. A first liquid concentrate filling space is filled with a first liquid concentrate composition containing 0.5 to 15.0% by mass of an organic acid, and a second liquid concentrate filling space is filled with a second liquid concentrate composition containing 0.5 to 15.0% by mass of a hydrogen carbonate. The first liquid concentrate composition discharged from the first liquid concentrate filling space and the second liquid concentrate composition discharged from the second liquid concentrate filling space are mixed to form a foam. The foam forming aerosol product can be safely used, has an excellent storage stability and is capable of readily forming a foam.
