Abstract

PROBLEM TO BE SOLVED: To prevent the exertion of an adverse influence on the human body even when an alkaline ion agent to be used for sterilization and disinfection of the human hands, tableware, foodstuffs and various kinds of articles is used for the sterilization and disinfection of fruits, vegetables, tableware, etc., by using alkaline ion water of oxidation reduction potential and pH in specific ranges. SOLUTION: This alkaline ion agent for sterilization and disinfection consists of the strong alkaline ion water having the oxidation reduction potential of >=50 mV and the pH value of 10 to 13 and is produced by an ordinary alkaline ion water producing means which has an anode and cathode and takes the alkaline ion water out of the cathode side by supplying electrolytic current to both electrodes. A stabilizer is added to such alkaline ion water. Sodium silicate, sodium phosphate or potassium phosphate alone or a mixture composed of >=2 kinds thereof is used as the stabilizer. This stabilizer is added to the alkaline ion water in such a manner that the concentration thereof attains <=1 wt.%. A similar sterilization effect may be obtained with such strong alkaline ion water even with a diluting liquid by water.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to sterilization of human hands, tableware, food and various articles for general and medical use.
The present invention relates to an alkali ion agent that can be used for sterilization.

[0002]

2. Description of the Related Art Alcohol-based chemicals are mainly used for sterilizing or removing bacteria such as human hands and tableware.

[0003]

Such conventional disinfecting and disinfecting agents are not suitable for disinfecting and disinfecting fruits, vegetables, tableware and the like which are directly eaten because of the components. The remaining components of the solution are problematic. In addition, sterilization
The effect of wastewater after disinfection on the environment is also a problem.

[0004]

Therefore, the present invention uses strongly alkaline ionized water, and particularly, has a redox potential of 50%.
Water can be obtained by electrolyzing water using alkaline ionized water having a pH of at least mV and in the range of pH 10 to pH 13, and does not adversely affect the human body or environment. Here, the reason why the alkaline ionized water is limited to pH 10 to pH 13 is that, in the case of alkaline ionized water having a pH of 10 or less, the expected disinfection and bactericidal effects cannot be expected, and at pH 13 there is a possibility of adversely affecting human skin. It is.

[0005] It is good to use this strongly alkaline ionized water immediately after its production, but since the pH value may decrease with the passage of time, the above value can be maintained for a long time by adding a small amount of a stabilizer. It is possible to keep without significant change. As the stabilizer, for example, sodium silicate, sodium phosphate, potassium phosphate and the like can be used alone or as a mixture of two or more kinds.

[0006] By adding such an amount that the concentration becomes 1% by weight or less, the value of pH 10 to pH 13 can be maintained without a large change for a long time. Also,
In the mixing, it is preferable that the mixing be performed immediately after the production of the alkaline ionized water without contact with air in an environment such as a nitrogen atmosphere. The present inventor has found that among various bacteria that inhabit in nature, heterotrophic bacteria as pathogens inhabit at an oxidation-reduction potential of 50 mV to -450 mV and at a pH value of about 2 to about 10. I understand.

[0007] Thus, the strongly alkaline ionized water of the present invention thus obtained has a redox potential of 350 mV, which is 50 mV or more, and has a pH value of 10 to 13, so that pathogenic bacteria can be killed almost immediately. confirmed. Note that the strong alkaline ionized water of the present invention has the same function and effect even when diluted with water, and in experiments, the value does not change even if the alkaline ionized water having a pH value of 11.7 is diluted twice. PH value 11.4 at 4 times, pH 1 at 6 times
1.1, pH value 10.8 at 8 times, pH value at 10 times, 10.
A value of 7 was obtained.

Further, even if a small amount of fragrance is added, the effect is not affected.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION An alkaline ionized water producing means having an anode and a cathode, and applying an electrolytic current to both electrodes to extract alkali ionized water from the cathode side, has a pH of 10
Take out strong alkaline ionized water having a pH of ~ 13. This strongly alkaline ionized water allows Escherichia coli, which is a typical heterotrophic bacterium, and O-15, which is a kind of the bacterium.
7: The bactericidal effect was tested using four types of bacteria, H7, Staphylococcus aureus and Salmonella.

In the test method, the number of each bacterium is measured in advance in a petri dish, and the above strongly alkaline ionized water is sprayed.
After 5 seconds, 10 seconds, 20 seconds, 30 seconds, and 60 seconds, the presence of the bacteria was observed to confirm the presence or absence of the bacteria. For all the bacteria, no inhabitation of the bacteria was confirmed at each elapsed time, and it was confirmed that the bacteria had an effective bactericidal effect.

Next, sodium silicate was added as a stabilizer to the alkaline ionized water having a pH of 12 at the time of the production so that the concentration became 0.5% by weight.
The value of 4 could be maintained after 9 months. In addition, sodium silicate and sodium phosphate were added as stabilizers to the alkaline ionized water having a pH of 12 at the time of the production so that the concentration was 0.25% by weight.
The value of 1.4 could be maintained after 9 months.

[0012] The strong alkaline ionized water containing the stabilizer was put into a sprayer and sprayed on fruits, vegetables, dishes and toilet seats, and after 5 seconds, 10 seconds, 20 seconds, 30 seconds and 60 seconds, respectively. Escherichia coli, O-157: H7, Staphylococcus aureus, and Salmonella were not found in all the elapsed times after the second.

[0013]

According to the present invention described in detail above, the alkali-ion water having an oxidation-reduction potential of 50 mV or more and a pH of 10 to 13 makes it possible to maintain the oxidation-reduction potential in a range of 50 mV to -450 mV and a pH value of Has the effect of immediately killing heterotrophic bacteria as pathogenic bacteria that can inhabit between about 2 and 10.

Further, even when used for sterilization and disinfection of fruits, vegetables, tableware, and the like, which are directly eaten, they have the effect of not adversely affecting the human body and having no odor or taste. Therefore, there is an effect that it can be used anywhere, such as a general household, a medical site, a food factory, etc., because a use place and a use object are not selected. Further, there is an effect that the wastewater after sterilization and sanitization does not adversely affect the environment.
