PROBLEM TO BE SOLVED: To provide a propellant for insecticidal-bactericidal use utilizing allyl isothiocyanate, having no persistence, being safe and exhibiting excellent insecticidal-bactericidal effects.SOLUTION: A propellant is characterized in that, in a pressure resistant container pressurizable in such a manner that liquefied carbon dioxide gas to be filled can retain a liquid state at ordinary temperature, natural allyl isothiocyanate and food additive ethanol are dissolved into the liquefied carbon dioxide gas filled into the pressure resistant container. A mixing ratio between a mixture of the natural allyl isothiocyanate and the food additive ethanol and the liquefied carbon dioxide gas is controlled so as to be approximately 2:98 in percent by weight. |
