PROBLEM TO BE SOLVED: To obtain the subject product excellent in stability of emulsification or dispersion of a propellant and capable of producing a foamed state after jetting comparable to that of a conventional product by using a larger amount of the propellant than that of the conventional product and filling a foamable aerosol composition prepared by regulating the particle diameter of particles obtained by emulsifying the propellant in a stock solution. SOLUTION: This aerosol product comprises a foamable aerosol composition prepared by emulsifying or dispersing 20-60 wt.% of a propellant in 40-80 wt.% of a stock solution and is obtained by regulating the average particle diameter of emulsified or dispersed particles to 0.01-10 μm. The aerosol product preferably comprises 45-75 wt.% of the stock solution comprising (A) 1-50 wt.% of an active component, (B) 0.5-8 wt.% of a surfactant and (C) 15-45 wt.% of a solvent and 25-55 wt.% of the propellant. A nonionic type surfactant having >=7.5 hydrophile-lipophile balance(HLB) is preferred as the component B. A monohydric alcohol such as ethyl alcohol is preferred as the component C. The foamable aerosol composition is preferably premixed in a mixer before filling into an aerosol container. |
