A water soluble bactericide is obtained by ozone-oxidizing glycerin. Specifically, a 0.1 to 20% glycerin aqueous solution and gas phase ozone obtained by ozonizing oxygen through contact between oxygen and a silent discharge field, are brought into gas-liquid contact with each other, thereby to ozone-oxdize glycerin. Alternatively, a 0.1 to 20% glycerin aqueous solution is electrolyzed, thereby to produce ozone directly in the glycerin aqueous solution.
