  • Water soluble bactericide and producing method thereof
    Patent number: 6781020
    Abstract: 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.
    Type: Grant

  • Water soluble bactericide and producing method thereof
    Publication number: 20030032668
    Abstract: A water soluble bactericide is obtained by ozone-oxidizing glyceline. Specifically, a 0.1 to 20% glyceline 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-oxidize glyceline. Alternatively, a 0.1 to 20% glyceline aqueous solution is electrolyzed, thereby to produce ozone directly in the glyceline aqueous solution.
