Contains at least 40 ppm of available chlorine and pH
Has a characteristic of 6.5 or less. The bactericidal action of the electrolytic germicidal water is due to available chlorine contained in the electrolytic germicidal water.
Alternatively, the bacteria enter the cells of the bacteria to be sterilized due to osmotic pressure or the like and lose the balance in the cells, thereby killing the bacteria. Conventionally, sterilizing water containing a chlorinated bactericide such as an aqueous solution of sodium hypochlorite has also been used, but this germicidal water also has the same bactericidal action as the above-mentioned bactericidal action.

高濃度の有効塩素を必要とする。The electrolytic sterilizing water and the sterilizing water containing a chlorine-based sterilizing agent include:
Although high bactericidal action can be obtained by available chlorine if taken up in the cells, sterilization from inside the cells is difficult because the biological membrane of bacteria tries to prevent the entry of available chlorine into the cells, and the electrolytic sterilizing water is used. The bactericidal action of is obtained by contact of available chlorine outside the cells. Therefore, in the electrolytic sterilizing water, effective chlorine is allowed to act from outside the cell, so that a high concentration of effective chlorine that can obtain a sufficient sterilizing effect even from outside the cell is required.

きる。The germicidal water containing a chlorine-based disinfectant and an aprotic substance contains the effective chlorine of the chlorine-based disinfectant in an aprotic substance. Since the aprotic substance is a necessary nutrient for the cells of the bacteria to be sterilized, the biological membrane of the bacteria takes up the aprotic substances containing available chlorine into the cells. When the effective chlorine enters the cells of the bacteria to be sterilized, the balance in the cells is disrupted and the bacteria can be killed. Therefore, since sterilization can be performed from inside the cells, a desired sterilizing action can be obtained with a low effective chlorine concentration. According to the third aspect of the present invention, the electrolytic sterilizing water produced by the electrolysis of the chloride salt solution and containing the aprotic substance is the available chlorine produced by the electrolysis of the chloride salt solution. Is included in the aprotic substance. Since the aprotic substance is a necessary nutrient for the cells of the bacteria to be sterilized, the biological membrane of the bacteria takes up the aprotic substances containing available chlorine into the cells. When the effective chlorine enters the cells of the bacteria to be sterilized, the balance in the cells is disrupted and the bacteria can be killed. Therefore, since sterilization can be performed from inside the cells, a desired sterilizing action can be obtained with a low effective chlorine concentration. Further, according to the present invention according to claim 5, the electrolytic sterilizing water generator includes an aprotic substance adding apparatus that adds an aprotic substance to at least one of a chloride salt solution and electrolytic sterilizing water. The electrolytic sterilizing water according to claim 1 can be generated. Also,,
According to the present invention according to claim 6, the sterilization method comprises the steps of:
By contacting sterilized water containing the chlorinated bactericide according to item (1) with the object to be sterilized, available chlorine enters the cells of the bacteria of the object to be sterilized, and the intracellular balance is lost, and the bacteria can be killed. Furthermore, according to the present invention according to claim 7, the sterilization method comprises contacting the electrolytic sterilizing water according to claim 3 with a sterilized substance, whereby effective chlorine enters the cells of the bacteria of the sterilized substance, The balance of the bacteria is lost and bacteria can be killed.

殺菌作用の持続性が良い。The electrolytic sterilizing water generated as described above is in a state in which available chlorine in the electrolytic sterilizing water generated in the anode chamber 13 is included in sucrose. When this electrolytically sterilized water is brought into contact with the material to be sterilized, the aprotic substance is a necessary nutrient for the cells of the bacteria in the substance to be sterilized. When the effective chlorine enters the cells of the bacteria to be sterilized, the balance in the cells is lost and the bacteria can be killed. Therefore, since sterilization can be performed from inside the cells, a desired sterilizing action can be obtained with a low effective chlorine concentration. In addition, by containing an aprotic substance, the viscosity of the electrolytic sterilizing water increases, and effective chlorine is hardly lost and decomposed,
Good germicidal action.

Furthermore, the sterilization method has been described by washing the object to be sterilized with electrolytic sterilizing water, but the method is not limited thereto. For example, the electrolytic sterilizing water is sprayed on the object to be sterilized, or the object to be sterilized is immersed in the electrolytic sterilizing water. In addition, a desired sterilizing action can be obtained by a method in which the electrolytic sterilizing water and the substance to be sterilized come into contact with each other. In addition, the electrolytic sterilizing water described as the electrolytic sterilizing water generated on the anode chamber side is not limited thereto, and the pH is adjusted to a weak alkaline electrolytic sterilizing water or a weak acid generated in a non-diaphragm type electrolytic cell. Electrolytic sterilizing water containing effective chlorine, such as electrolytic sterilizing water, can provide a desired sterilizing action.
