Description

Manufacturing of chlorine dioxide water with improved long-term stability, eco-friendly sterilization, disinfection 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 sterilization, disinfection and deodorizing agent using the same, and a manufacturing method thereof. It relates to a sterilization, disinfection and deodorizing agent that can be stored for a long time, is eco-friendly and has excellent sterilization performance, and a manufacturing method thereof.

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

These sterilizers are mainly in liquid form or gel form, and the main component may be mainly ethanol or lax component.

However, in the case of hand sanitizers made of ethanol, the sterilization power is low due to the limitation of the content, so the prevention of infectious diseases may be weak, and there is a limitation that the shelf life is very short because of the strong volatility.

In addition, chlorine-based disinfectants, such as Lax products, have reduced sterilization power when the pH is increased, have a very strong chlorine smell, produce carcinogens such as trihalomethanes and harol acetic acid, and have limitations in which various pathogenic microorganisms reproduce.

Alcohol-based products are mainly applied to food, act in neutrality, have little effect on Bacillus, volatilize at high temperature, have high flammability, and cause skin irritation and troubles, so there are limitations that are not suitable for human safety.

In addition, in the case of a general fiber deodorant, sterilization power is limited, and there is a limitation in that durability is insufficient due to odor neutralization methods such as 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 material that is easily decomposed by light. , it has comprehensive sterilization power including viruses, can oxidize and decompose odor substances such as spaces and instruments, and has excellent effects in inhibiting the re-reproduction of various hospital microorganisms and removing harmful heavy metals.

In addition, since chlorine dioxide water does not oxidize organic matter, it does not generate carcinogenic substances such as trihaomethane (THM), haloacetic acids (HAAs), and other chlorinated organic compounds, so it is environmentally friendly and harmless to the human body. .

However, since chlorine dioxide is unstable at room temperature and is easily decomposed into ClO ₂ -, ClO ₃ -, Cl-, etc., it is difficult to store it for a long time.

In particular, conventional disinfectants using chlorine dioxide water have a problem in that the usable period is very short because the concentration of dissolved chlorine dioxide cannot be stably maintained after opening.

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.

Republic of Korea Patent Publication No. 10-2020-0002336 (2020.01.08)

To this end, the present invention basically provides a step S10 for preparing chlorine dioxide water, a step S20 for preparing stabilized chlorine dioxide water, and a step S30 for preparing a first solution whose concentration is adjusted by adding distilled water to the stabilized chlorine dioxide water. , by adding an additive to the first solution, including the step S40 of preparing a second 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 sodium chlorite (NaClO ₂ ) aqueous solution and hydrochloric acid (HCl) in water. .

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

Next, the step S20 is a step to prepare a stabilized chlorine dioxide water by adding a pH adjuster and a red ginseng ferment extract to the chlorine dioxide water prepared in step S10 to maintain the concentration for a long period of time. can be manufactured.

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

More specifically, in step S20, after reacting by adding a pH adjuster to the chlorine dioxide water prepared in step S10, fermented red ginseng extract may be further added to stabilize the chlorine dioxide water.

Here, the pH adjusting agent includes monosodium hydrogen phosphate, and the pH adjusting agent 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 fermented red ginseng 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 fermented red ginseng extract can suppress the generation of chlorine dioxide gas, thereby stabilizing the chlorine dioxide water.

At this time, the stabilized chlorine dioxide water has a wide range of sterilization power of pH 2 to 10 and can maintain a long-term concentration with a stable pH condition by a pH adjuster containing monosodium hydrogen phosphate.

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

The decomposition 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 for the forward reaction.

[Scheme 1]

A + B ↔ C + D

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

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

[Scheme 2]

2ClO ₂ + H ₂ O ↔ HClO ₂ + HClO ₃

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

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

More specifically, in step S30, distilled water is added to the stabilized chlorine dioxide to adjust the chlorine dioxide concentration to 10 to 200 ppm to prepare a first solution.

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

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

Here, the red ginseng fermented extract and wood vinegar extract, which are additives, are additives for increasing and stabilizing the sterilization and deodorization effects, and suppress the decomposition of chlorine dioxide water so that the concentration is maintained for a long time.

More specifically, in the step S40, the fermented red ginseng extract is added in an amount of 0.02 to 0.2 parts by weight based on 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 based on 100 parts by weight of the first solution. It is preferably added.

When the fermented red ginseng extract is added in an amount of less than 0.02 parts by weight, the effect for improving the stability of chlorine dioxide is very insignificant, and when it is added in excess of 0.2 parts by weight, economic efficiency is lowered due to cost improvement.

When the wood vinegar extract is less than 0.02 parts by weight or more than 0.2 parts by weight, the effect for improving the long-term stability of chlorine dioxide becomes insignificant.

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

In this case, the wood vinegar extract is characterized in that it is a liquid extract extracted by adding calcium carbonate to the purified wood vinegar and performing a mixed reaction.

More specifically, the wood vinegar extract is an extract extracted by mixing purified wood vinegar and calcium carbonate and reacting for 24 hours in an extraction reactor. .

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

More specifically, the fermented red ginseng extract is a liquid extract extracted by reacting fermented red ginseng obtained by culturing in a fermenter at 25 to 35° C. for 68 to 76 hours at 25 to 35° C. for 22 to 26 hours in an extraction reactor after dry grinding.

At this time, the microorganism used for the preparation of the fermented red ginseng extract is characterized in that it contains Bacillus subtilis.

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

In addition, it may further include the step S50 of formulating and subdividing the second solution prepared in step S40 as needed. In this case, the second solution may be subdivided into 100ml, 500ml, 1L, 20L, etc. depending on the use, but the subdivided amount is not limited thereto.

The sterilization, disinfection and deodorizing agent manufactured according to the manufacturing method described above is made of oxygen, so it is safe, has excellent sterilization and deodorization performance, and has the effect of maintaining concentration and stabilization for more than one year, so it has the advantage that it can be used for a long time after opening as well as before opening.
