The present invention has as its object the provision of a cracking aerosol composition which has cracking characteristics in that a foam-breaking sound is generated with the spontaneous breakage of foam formed by foaming generated by the action of carbon dioxide and a liquefied petroleum gas in a flowable discharge and which can reduce the proportion of the liquefied petroleum gas. The cracking aerosol composition of the present invention is a cracking aerosol composition to be filled into an aerosol container including a pressure-resistant container having an aerosol valve, wherein the cracking aerosol composition contains a liquefied petroleum gas, water, a defoaming oil, a lower alcohol, carbon dioxide, an emulsifier and an emulsifying aid； the proportion of the liquefied petroleum gas is 20.0 to 55.0 mass %, the proportion of the defoaming oil is 0.5 to 12.0 mass %, the proportion of the lower alcohol is 5.0 to 30.0 mass %, the proportion of the carbon dioxide is 0.1 to 3.5 mass % and the proportion of the emulsifier is 0.02 to 1.2 mass %； and the emulsifier includes two types of nonionic surfactants having different HLB values, and the mass ratio of the two types of nonionic surfactants is 1:10 to 10:1.
