This aqueous solution is appropriately diluted according to the application, and for example, for disinfecting drinking water or pool water, 1
mg / liter (hereinafter, liter is represented by L), about 200 mg / L for disinfecting medical instruments, about 100 to 200 mg / L for disinfecting foods, and about 100 to 200 mg / L for disinfecting dishes, cooking utensils and food manufacturing equipment. It is used at a concentration of about 200 to 400 mg / L and for disinfection of floors and the like at a concentration of about 200 to 400 mg / L. In addition, calcium hypochlorite is obtained by adding powdered powder [Ca (ClO) 2 · CaCl 2 · 2H 2

Thus, in these hypochlorite aqueous solutions, high P
In the H region, hypochlorite ion (Cl O − ) is large and PH
And the amount of hypochlorous acid (HOCl) increases. Therefore, in order to increase the sterilizing power, it is important to set the pH low so that the proportion of hypochlorous acid increases.
As H becomes lower, the production of highly toxic chlorine gas (Cl 2 ) increases.

られるが、より安価であるという利点がある。[0006] Stabilized chlorine dioxide and sodium chlorite have a strong bactericidal action based on an oxidative reaction against microorganisms such as bacteria, viruses, spores and algae. In other words, microorganisms absorb nutrients and excrete them, but the excrement is acidic and reacts with chlorine dioxide to produce hypochlorous acid and nascent oxygen. Is released, and this reaction proceeds along the secretory pathway of excrement into the cells of the microorganism, and the cells are destroyed by the generated nascent oxygen. Since chlorine dioxide has a low reactivity with ammonia and nitrogen compounds, it has an advantage that sterilization can be maintained even in the presence of organic substances. Sodium chlorite is considered to have the same bactericidal action as stabilized chlorine dioxide, but has the advantage of being cheaper.

様である。[0007] However, stabilized chlorine dioxide has a pH of about 7.5 when dissolved in water, and has an oxidizing power about 2.6 times that of sodium hypochlorite. It is. Therefore, in order to more strongly exert a bactericidal action, the pH is generally adjusted to 4 or less and used. However, a decrease in the PH greatly increases the generation of toxic chlorine dioxide gas. This is the same in the case of sodium chlorite.

と規定されている。As described above, in the disinfection using a chlorine-based disinfectant, it is desirable to set the pH of the aqueous solution low in order to increase the disinfecting power of any disinfectant. The lower the pH, the more toxic gas is generated, which causes a problem of deteriorating the working environment. Incidentally, the allowable concentration of chlorine gas is specified as 1 ppm or less and chlorine dioxide gas is specified as 0.3 ppm or less as the allowable concentration in the Japanese Society of Health.

An acidic solution having an H value of 5.5 or less, a residual chlorine amount of 30 ppm or more, and an oxidation-reduction potential of +800 mV or more is prepared. In this case, even if the pH is in the range of 5 to 5.5, the amount of chlorine gas generated when the residual chlorine amount is increased. However, since the concentration exceeds the above allowable concentration, the problem of the working environment cannot be completely eliminated.

It may take a considerable number of days during the distribution process from manufacturing to the user, and it is rare for the user to purchase and use it immediately, and often store it irregularly until it becomes necessary. Therefore, it is required that storage stability is excellent in order to exhibit sufficient disinfecting power at the time of use, but chlorine-based disinfectants generally maintain a stable disinfecting power over a long period of time because they are highly degradable. Is difficult. In addition, since the use of disinfection is wide-ranging, workers often lack chemical knowledge,
Consideration must also be given to facilitating the preparation of a disinfectant solution having a concentration suitable for the intended use and to prevent erroneous operations.

に設定する必要がある。FIG. 1 shows the relationship between the percentage of available chlorine in an aqueous solution of sodium hypochlorite and PH. From this figure, it can be seen that the proportion of hypochlorite ion (ClO − ) increases as the PH increases, and as the pH decreases, the hypochlorous acid (HOO) decreases.
The ratio of Cl) increases, and the percentage of hypochlorous acid becomes the maximum around pH 4 to 5. However, as the pH further decreases, the ratio of hypochlorous acid decreases and chlorine gas (Cl 2 ) increases. It can be seen that the generation of From the figure, PH
Above about 5, it seems that no chlorine gas is generated,
Actually, there is a chlorine gas smell, and the measured value can be obtained by a chlorine gas detector tube. Therefore, in order to suppress the generation of chlorine gas to a trace amount that does not cause a problem in health and safety, the pH is set to 5.
It is necessary to be 5 or more. When the pH is higher than 7.5, the proportion of hypochlorous acid is remarkably reduced. Therefore, the pH must be set to 7.5 or less in order to ensure a sufficient sterilizing and disinfecting power.

生じる。On the other hand, the preparation for sterilization and disinfection of the present invention is a solid (including powdery) preparation for sterilization and disinfection obtained by mixing a high-grade mash powder and an acidic agent powder in a specific ratio. Thus, it is possible to prepare a germicidal disinfectant that exhibits the same excellent germicidal action as the first germicidal disinfectant and suppresses the generation of toxic gas to a very small amount. And
The mixing ratio is in the range of 40 to 200 parts by weight of the acid agent powder with respect to 100 parts by weight of the high-grade salad powder. When the acid agent powder is less than 40 parts by weight, a sufficient sterilizing and disinfecting action cannot be obtained. If the amount exceeds 200 parts by weight, the pH of the aqueous solution becomes too low, and there is a problem on safety and health due to generation of chlorine gas.

In order to be compatible with the sterilization and disinfection in the food-related field by combination with the advanced salami powder as an additive, it is desirable that the component is a component specified in the food additive, and succinic acid, citric acid, malic acid, Tartaric acid is recommended. In particular, succinic acid is most suitable because it has a smaller hygroscopicity than other acidic agents and has a dry feeling of powder, and is excellent in storage stability of a disinfecting solution obtained by dissolving the disinfecting preparation in water. It is. On the other hand, adipic acid is a powdery acid agent specified in food additives, but is unsuitable due to its low solubility in water.Fumaric acid, which is also a powdery acid agent, is water-soluble. However, there is a problem that the solubility in oxidizing atmosphere is low and the solubility in oxidizing atmosphere is low.

け製剤が嵩高になって流通及び使用上で不利となる。[0026] By the way, since high-grade salad powder is alkaline, direct contact of the powders with an acidic agent is not appropriate from the viewpoint of storage stability. Therefore, in the preparation for disinfecting and disinfecting of the present invention, a mixture of a high-grade salami powder and an acid agent powder, and a contact interfering agent powder for preventing contact between the both are recommended as those having particularly excellent storage stability. . The compounding amount of such a contact disturbing agent powder is preferably in the range of 20 to 800 parts by weight based on 100 parts by weight of the high-grade salad powder. If the amount is too small, a sufficient contact disturbing effect cannot be obtained. On the other hand, if the blending amount is too large, the content ratio of the high-grade salami powder in the formulation becomes too small, and the amount of the formulation used must be increased in order to obtain the required sterilizing and disinfecting power, and the formulation becomes bulky accordingly. Disadvantageous in distribution and use.

For example, sodium sulfate, potassium sulfate, calcium sulfate, sodium chloride, carbonate In addition to powders of inorganic compounds such as sodium hydrogen, powders of carbohydrates such as glucose, lactose, sucrose, dextrin, and starch can be used. However, among these, sodium sulfate does not consume effective chlorine because it has no reactivity to high-grade ash powder, and does not impair the stability of high-grade ash powder because of its low hygroscopicity. It is particularly suitable because it is easily dissolved in water and does not cause a pH change of the disinfectant solution, and a dry powder is easily obtained, which is also specified for food additives. On the other hand, calcium chloride is a component contained in the ground bean powder, but has a high hygroscopicity, and thus may impair the stability of the ground bean powder.

This aqueous solution is appropriately diluted according to the application, and for example, for disinfecting drinking water or pool water, 1
mg / liter (hereinafter, liter is represented by L), about 200 mg / L for disinfecting medical instruments, about 100 to 200 mg / L for disinfecting foods, and about 100 to 200 mg / L for disinfecting dishes, cooking utensils and food manufacturing equipment. It is used at a concentration of about 200 to 400 mg / L and for disinfection of floors and the like at a concentration of about 200 to 400 mg / L. In addition, calcium hypochlorite is obtained by adding powdered powder [Ca (ClO) 2 · CaCl 2 · 2H 2

Thus, in these hypochlorite aqueous solutions, high P
In the H region, there are many hypochlorite ions (Cl O-),
And the amount of hypochlorous acid (HOCl) increases. Therefore, in order to increase the sterilizing power, it is important to set the pH low so that the proportion of hypochlorous acid increases.
As H becomes lower, the production of highly toxic chlorine gas (Cl 2 ) increases.

られるが、より安価であるという利点がある。[0006] Stabilized chlorine dioxide and sodium chlorite have a strong bactericidal action based on an oxidative reaction against microorganisms such as bacteria, viruses, spores and algae. In other words, microorganisms absorb nutrients and excrete them, but the excrement is acidic and reacts with chlorine dioxide to produce hypochlorous acid and nascent oxygen. Is released, and this reaction proceeds along the secretory pathway of excrement into the cells of the microorganism, and the cells are destroyed by the generated nascent oxygen. Since chlorine dioxide has a low reactivity with ammonia and nitrogen compounds, it has an advantage that sterilization can be maintained even in the presence of organic substances. Sodium chlorite is considered to have the same bactericidal action as stabilized chlorine dioxide, but has the advantage of being cheaper.

様である。[0007] However, stabilized chlorine dioxide has a pH of about 7.5 when dissolved in water, and has an oxidizing power about 2.6 times that of sodium hypochlorite. It is. Therefore, in order to more strongly exert a bactericidal action, the pH is generally adjusted to 4 or less and used. However, a decrease in the PH greatly increases the generation of toxic chlorine dioxide gas. This is the same in the case of sodium chlorite.

The lower the pH, the more toxic gas is generated, which causes a problem of deteriorating the working environment. Incidentally, the allowable concentration of chlorine gas is specified as 1 ppm or less and chlorine dioxide gas is specified as 0.3 ppm or less as the allowable concentration in the Japanese Society of Health.

It may take a considerable number of days during the distribution process from manufacturing to the user, and it is rare for the user to purchase and use it immediately, and often store it irregularly until it becomes necessary. Therefore, it is required that storage stability is excellent in order to exhibit sufficient disinfecting power at the time of use, but chlorine-based disinfectants generally maintain a stable disinfecting power over a long period of time because they are highly degradable. Is difficult. In addition, since the use of disinfection is wide-ranging, workers often lack chemical knowledge,
Consideration must also be given to facilitating the preparation of a disinfectant solution having a concentration suitable for the intended use and to prevent erroneous operations.

It is possible to prepare a germicidal disinfectant that exhibits an excellent germicidal disinfecting action and suppresses the generation of toxic gas to a very small amount. The mixing ratio is such that the acidifier powder is in the range of 40 to 200 parts by weight based on 100 parts by weight of the high-grade salad powder, and if the acidifier powder is less than 40 parts by weight, a sufficient sterilizing and disinfecting action cannot be obtained. On the other hand, when the amount exceeds 200 parts by weight, the pH of the aqueous solution becomes too low, which causes a problem on safety and health due to generation of chlorine gas.

よって完全に溶解する。FIG. 1 shows the relationship between the percentage of available chlorine in an aqueous solution of sodium hypochlorite and PH. From this figure, it can be seen that the higher the PH, the higher the percentage of hypochlorite ion (ClO-), and the lower the pH, the lower the hypochlorous acid (HOO).
The ratio of Cl) increases, and the percentage of hypochlorous acid becomes the maximum around pH 4 to 5. However, as the pH further decreases, the ratio of hypochlorous acid decreases and chlorine gas (Cl 2 ) increases. It can be seen that the generation of From the figure, PH
Above about 5, it seems that no chlorine gas is generated,
Actually, there is a chlorine gas smell, and the measured value can be obtained by a chlorine gas detector tube. Therefore, in order to suppress the generation of chlorine gas to a trace amount that does not cause a problem in health and safety, the pH is set to 5.
It is necessary to be 5 or more. When the pH is higher than 7.5, the proportion of hypochlorous acid is remarkably reduced. Therefore, the pH must be set to 7.5 or less in order to ensure a sufficient sterilizing and disinfecting power. High-grade salami powder does not sufficiently dissolve simply by being introduced into water because it is alkaline and contains calcium, but is completely dissolved by adjusting the pH to 7.5 or less.

In order to be compatible with the sterilization and disinfection in the food-related field by combination with the advanced salami powder as an additive, it is desirable that the component is a component specified in the food additive, and succinic acid, citric acid, malic acid, Tartaric acid is recommended. In particular, succinic acid is most suitable because it has a smaller hygroscopicity than other acidic agents and has a dry feeling of powder, and is excellent in storage stability of a disinfecting solution obtained by dissolving the disinfecting preparation in water. It is. On the other hand, adipic acid is a powdery acid agent specified in food additives, but is unsuitable due to its low solubility in water.Fumaric acid, which is also a powdery acid agent, is water-soluble. However, there is a problem that the solubility in oxidizing atmosphere is low and the solubility in oxidizing atmosphere is low.

け製剤が嵩高になって流通及び使用上で不利となる。By the way, since high-grade ash powder is alkaline, direct contact of the powders with an acidic agent is not appropriate from the viewpoint of storage stability. Therefore, in the preparation for disinfecting and disinfecting of the present invention, a mixture of a high-grade salami powder and an acid agent powder, and a contact interfering agent powder for preventing contact between the both are recommended as those having particularly excellent storage stability. . The compounding amount of such a contact disturbing agent powder is preferably in the range of 20 to 800 parts by weight based on 100 parts by weight of the high-grade salad powder. If the amount is too small, a sufficient contact disturbing effect cannot be obtained. On the other hand, if the blending amount is too large, the content ratio of the high-grade salami powder in the formulation becomes too small, and the amount of the formulation used must be increased in order to obtain the required sterilizing and disinfecting power, and the formulation becomes bulky accordingly. Disadvantageous in distribution and use.

う懸念がある。The above-mentioned contact disturbing agent may be any as long as it has a low reactivity to high-grade ash powder and a small effect on the pH of the disinfectant solution. For example, sodium sulfate, potassium sulfate, calcium sulfate, sodium chloride, carbonate In addition to powders of inorganic compounds such as sodium hydrogen, powders of carbohydrates such as glucose, lactose, sucrose, dextrin, and starch can be used. However, among these, sodium sulfate does not consume effective chlorine because it has no reactivity to high-grade ash powder, and does not impair the stability of high-grade ash powder because of its low hygroscopicity. It is particularly suitable because it is easily dissolved in water and does not cause a pH change of the disinfectant solution, and a dry powder is easily obtained, which is also specified for food additives. On the other hand, calcium chloride is a component contained in the ground bean powder, but has a high hygroscopicity, and thus may impair the stability of the ground bean powder.
