(57) [Summary] [PROBLEMS] The mixing ratio of a propellant to an aqueous stock solution is high, The product can be miniaturized and form a uniform phase. Provided is an aerosol product that contains a foamable aerosol composition having no problem with the dispersion state and has a low injection sound. SOLUTION: An aqueous stock solution comprising 1 to 30% by weight of a surfactant, 5 to 30% by weight of a lower alcohol, 1 to 50% by weight of an active ingredient and the balance of water, and 40 to 90% by weight of a propellant. An aerosol product containing an aerosol composition consisting of 60% by weight and having an injection sound of 50 dB or less when discharged in a foamed state. |
