Description

Manufacturing of chlorine dioxide water with improved long-term stability, eco-friendly sterilizing, disinfecting and deodorizing agent using the same, and manufacturing method thereof SAME}

The present invention relates to the production of chlorine dioxide water with improved long-term stability, an eco-friendly sterilizing, disinfecting and deodorizing agent using the same, and a manufacturing method thereof. More specifically, the long-term stability is improved by suppressing the decomposition of chlorine dioxide using fermented red ginseng extract and wood vinegar extract. It relates to a sterilizing, disinfecting and deodorizing agent that can be stored for a long period of time, is environmentally friendly, and has excellent sterilizing performance, and a method of manufacturing the same.

Recently, as highly contagious infectious diseases such as Corona, MERS, SARS, and bird flu occur periodically, interest in personal hygiene products that can disinfect hands or sterilize products to prevent viral infection is increasing. there is.

These disinfectants are mainly in liquid or gel form, and the main ingredient may mainly be ethanol or bleach.

However, in the case of hand sanitizers made of ethanol, the sterilizing power may be reduced due to content limitations, making it vulnerable to preventing infectious diseases, and because it is highly volatile, there is a limitation of its very short shelf life.

In addition, chlorine-based disinfectants such as bleach products have reduced sterilizing power when pH increases, have a strong chlorine smell, produce carcinogens such as trihalomethane and harol acetic acid, and have limitations in reproducing various hospital microorganisms.

Alcohol-based products are mainly applied to the food industry, act in a neutral environment, have minimal effect on Bacillus bacteria, volatilize at high temperatures, are highly flammable, cause skin irritation and trouble, and have limitations that make them unsuitable for human safety.

In addition, in the case of general fabric deodorizers, the sterilizing power is limited, and there is a limitation of insufficient sustainability as a method of neutralizing odors in textiles and household furniture.

On the other hand, chlorine dioxide water has a sterilizing effect in a wide pH range and is an environmentally friendly substance that is easily decomposed by light. It can be used as a sterilizing disinfectant and has a sterilizing power 2.5 times that of hypochlorous acid and 5 times that of stable chlorine. , it has comprehensive sterilizing power including viruses, can oxidize and decompose odorous substances in spaces and equipment, and is excellent at suppressing the regrowth of various hospital microorganisms and removing harmful heavy metals.

In addition, chlorine dioxide water does not oxidize organic substances, so it does not produce carcinogenic substances such as trihaomethane (THM), haloacetic acids (HAAs), and other chlorinated organic compounds, making it eco-friendly and harmless to the human body. .

However, chlorine dioxide is unstable at room temperature and easily decomposes into ClO ₂ -, ClO ₃ -, Cl-, etc., so there is a limitation that makes long-term storage difficult.

In particular, conventional disinfectants using chlorine dioxide water have the problem of being unable to maintain a stable concentration of dissolved chlorine dioxide after opening, resulting in a very short usable period.

Therefore, there is a need to manufacture a disinfectant containing chlorine dioxide that can be stored and distributed for a long time by maintaining the concentration of chlorine dioxide water for a long period of time.

Hereinafter, with reference to the attached drawings, the present invention will specifically describe the production of chlorine dioxide water with improved long-term stability, an eco-friendly sterilizing, disinfecting and deodorizing agent using the same, and a method for producing the same.

Figure 1 is a flow chart showing the production of chlorine dioxide water with improved long-term stability according to the present invention and the production method of an eco-friendly disinfection, disinfection and deodorant using the same.

As shown in Figure 1, the present invention relates to the production of chlorine dioxide water with improved long-term stability, an eco-friendly sterilizing, disinfecting and deodorizing agent using the chlorine dioxide water produced thereby, and a method for manufacturing the same. The present invention relates to the production of chlorine dioxide water with improved long-term stability. We propose a manufacturing method for a sterilizing, disinfecting and deodorizing agent that can be used for hand disinfection and space disinfection using chlorine water, can maintain long-term concentration, can be used for more than a year, is harmless to the human body, and is eco-friendly and has high-performance sterilization, disinfection and deodorization functions. .

For this purpose, the present invention basically includes step S10 of preparing chlorine dioxide water, step S20 of preparing stabilized chlorine dioxide water, and step S30 of preparing a first solution with adjusted concentration by adding distilled water to the stabilized chlorine dioxide water. , including step S40 of preparing a second solution by adding additives to the first solution.

Here, step S10 of preparing the chlorine dioxide water is a step of preparing chlorine dioxide water by dissolving chlorine dioxide (ClO ₂ ) gas generated by reacting an aqueous solution of sodium chlorite (NaClO ₂ ) with hydrochloric acid (HCl) in water. .

The chlorine dioxide water prepared in step S10 is an unstabilized chlorine dioxide water in which the concentration of dissolved chlorine dioxide is continuously reduced.

Next, step S20 is a step of preparing stabilized chlorine dioxide water by maintaining the concentration for a long period of time by adding a pH adjuster and fermented red ginseng extract to the chlorine dioxide water prepared in step S10. Chlorine dioxide water with improved long-term stability is produced. It can be manufactured.

Here, the stabilized chlorine dioxide water preferably has a dissolved chlorine dioxide concentration of 10 to 1000 ppm.

More specifically, in step S20, the chlorine dioxide water prepared in step S10 can be reacted by adding a pH adjuster and then further adding red ginseng fermentation extract to stabilize the chlorine dioxide water.

Here, the pH adjuster includes sodium hydrogen phosphate monobasic, and the pH adjuster is preferably added in an amount of 0.1 to 0.2 parts by weight based on 100 parts by weight of the chlorine dioxide prepared in step S10.

The red ginseng fermentation extract is preferably added in an amount of 0.1 to 0.2 parts by weight based on 100 parts by weight of the chlorine dioxide solution prepared in step S10.

Here, the red ginseng fermented extract can suppress the generation of chlorine dioxide gas and has the effect of stabilizing chlorine dioxide water.

At this time, the stabilized chlorine dioxide water has a wide range of sterilizing power in the pH range of 2 to 10, and can maintain the concentration for a long period of time under stable pH conditions by using a pH adjuster containing sodium hydrogen phosphate monobasic.

That is, in step S20, stabilized chlorine dioxide that can be maintained at room temperature for a long period of time can be produced by adding a pH adjuster and fermented red ginseng extract to unstabilized chlorine dioxide water.

The degradation inhibitor used in the present invention will be described in more detail. In the present invention, the decomposition inhibitor of chlorine dioxide is an inhibitor of the forward reaction.

[Scheme 1]

A + B ↔ C + D

As shown in Scheme 1, A and B produce C and D through the forward reaction, and the products C and D are reduced to A and B through the reverse reaction.

Here, a decomposition inhibitor is added to suppress the decrease in concentration due to the forward reaction of A and B, thereby suppressing the decrease in concentration due to side reactions such as decomposition of A and B for a long period of time.

[Scheme 2]

_2ClO2 + H ₂ O ↔ HClO ₂ + _HClO3

As shown in Scheme 2, chlorine dioxide and distilled water are decomposed into chlorous acid and chloric acid through a forward reaction. The reaction is suppressed by administering a decomposition inhibitor and the acidity is maintained by a pH adjuster, thereby converting chlorate to chloric acid and chlorite to chlorous acid. By suppressing the decomposition of chlorine, the concentration can be maintained for a long period of time.

Next, step S30 is a step of preparing a first solution whose concentration is adjusted by adding distilled water to the stabilized chlorine dioxide solution prepared in step S20.

More specifically, in step S30, the first solution can be prepared by adding distilled water to the stabilized chlorine dioxide to adjust the chlorine dioxide concentration to 10 to 200 ppm.

Next, step S40 is a step of preparing a second solution by adding fermented red ginseng extract and wood vinegar extract to the first solution prepared in step S30.

More specifically, in step S40, a sterilizing, disinfecting and deodorizing agent using chlorine dioxide water with improved long-term stability can be manufactured by adding red ginseng fermentation extract and wood vinegar extract as additives to the first solution.

Here, the additives, red ginseng fermentation extract and wood vinegar extract, are additives to increase and stabilize the sterilization and deodorization effect, and prevent the decomposition of chlorine dioxide water to maintain the concentration for a long period of time.

More specifically, in step S40, the red ginseng fermentation extract is added from 0.02 to 0.2 parts by weight with respect to 100 parts by weight of the first solution, and the content of the wood vinegar extract is 0.02 to 0.2 parts by weight with respect to 100 parts by weight of the first solution. It is desirable to add

If the fermented red ginseng extract is added in less than 0.02 parts by weight, the effect for improving the stability of chlorine dioxide is very minimal, and if it is added in excess of 0.2 parts by weight, economic feasibility is reduced due to increased cost.

If the wood vinegar extract is less than 0.02 parts by weight or exceeds 0.2 parts by weight, the effect for improving the long-term stability of chlorine dioxide is minimal.

That is, adding 0.2 to 0.2 parts by weight of the red ginseng fermentation extract and the wood vinegar extract, respectively, based on 100 parts by weight of the first solution is the optimal ingredient ratio for the long-term stability effect of chlorine dioxide.

At this time, the wood vinegar extract is characterized as a liquid extract extracted by adding calcium carbonate to purified wood vinegar and mixing reaction.

More specifically, the wood vinegar extract is an extract obtained by mixing purified wood vinegar and calcium carbonate and reacting in an extraction reactor for 24 hours. The wood vinegar extract suppresses the generation of chlorine gas, improves stability, and has excellent deodorizing effects. .

In addition, the red ginseng fermented extract added in steps S20 and S40, respectively, is preferably a liquid extract obtained by extracting fermented red ginseng obtained by culturing a fermentor using microorganisms.

More specifically, the fermented red ginseng extract is a liquid extract obtained by drying and pulverizing fermented red ginseng obtained by culturing the fermented red ginseng using self-contained microorganisms in a fermenter for 68 to 76 hours at 25 to 35 ° C. and reacting it in an extraction reactor for 22 to 26 hours.

At this time, the microorganism used to produce the fermented red ginseng extract is characterized in that it includes Bacillus subtilis.

As such, the present invention can be manufactured as an eco-friendly sterilizing, disinfecting and deodorizing agent by adjusting the concentration and adding additives in steps S30 and S40 using chlorine dioxide water with improved long-term stability prepared in step S20.

In addition, a step S50 of formulating and distributing the second solution prepared in step S40 may be further included as necessary. At this time, the second solution can be divided into 100ml, 500ml, 1L, 20L, etc. depending on the purpose, but the small volume is not limited to this.

The sterilizing, disinfecting and deodorizing agent manufactured according to the manufacturing method described above is made of oxygen, is safe, has excellent sterilizing and deodorizing performance, and has the effect of maintaining concentration and stabilization for a long period of more than one year, so it has the advantage of being able to be used for a long time not only before opening but also after opening.
