Abstract

When a virus or bacterial infection spreads, we face the question of whether the virus or sterilization was done correctly. If the cleaning agent or disinfectant is transparent, it is difficult to see even if cleaning or disinfecting is done, making it impossible to know whether it is being done correctly. In order to make the cleaning or disinfecting solution effective, it is necessary to allow a removal time of more than an appropriate amount of time, but it must be wiped off immediately after spraying. There are problems such as the lack of removal time, the difficulty in easily confirming whether the transparent liquid is effective in eliminating bacteria, and the inability to clean and disinfect with large amounts of water in areas with water shortages. It is colored so that it can be seen by detergents and disinfectants, and by incorporating a pH indicator that becomes colorless when it reacts from basic to acidic side into basic substances, the cleaning and disinfecting power can be recognized, and the object is cleaned and disinfected by visual inspection. In addition, the color disappearance time provides time for removal of viruses and bacteria, thereby improving the safety of cleaning and disinfection with the minimum amount of liquid required.

Description

Visible disinfectant solution

In the present invention, a pH indicator that can be visually recognized by adding color to a transparent detergent or disinfectant, and which becomes colorless when reacting from basic to acidic side, is mixed with a basic substance to improve the stability of cleaning and disinfection and to improve cleaning and disinfecting power. It is about a visible disinfection liquid that can be recognized and cleans and disinfects with the minimum amount of liquid.

In a cleaning agent that causes a cleaning solution to adhere to the surface of a tire wheel in the form of bubbles and removes contaminants attached to the surface of the object being cleaned, the cleaning agent contains a surfactant, an indicator that changes color when changed from alkaline to neutral, carbon dioxide gas and There are detergents that react and lose alkaline compounds.

Japanese Patent No. 3464491

When a virus or bacterial infection spreads, we are faced with the problem of how to remove it and whether hygiene management can be carried out correctly.

If the cleaner or disinfectant is transparent, even if the protective clothing, clothes, examination tables, and reception counters worn by doctors are disinfected, it is impossible to know whether they have been properly disinfected.

It is unclear whether transparent cleaners and disinfectants can be reliably sprayed, applied, or sprayed to the target area during surface treatment to remove and sterilize bacteria, viruses, etc.

In order to make the effect of the cleaner or disinfectant effective, it is necessary to take a removal time, and it is necessary to allow an appropriate period of time to elapse. The removal time for bacteria and viruses is short, and pathogens that are still alive adhere to the fabric, causing the remaining pathogens to spread widely.

In addition, general cleansers and disinfectants for finger and hand skin are colorless and transparent, and it is difficult to tell whether the liquid is water or disinfectant just by looking at it, and it is also impossible to know the level of cleaning and disinfection power it has, and it is written as a disinfectant solution. It's unsettling because we're just judging by the label.

Wet towels, wet tissues, etc. used before meals are actually wet, so there is no way to detect if bacteria develop during packaging, so it is not easy to check whether they are effective in eliminating bacteria.

It is necessary to supervise and supervise infants and children with a low sense of crisis to ensure that they are properly cleaned and disinfected, but when the number of people increases, such as in kindergartens and daycare centers, there is concern about whether they are properly sterilized due to lack of attention.

In addition, the iodine solution used for disinfection is dark brown, and you can check whether the detergent or disinfectant has been properly sprayed on your fingers or wrist. However, a large amount of water is used to remove the color, and it is effective in places where water is abundant. , it cannot be said to be effective in areas or environments where water is scarce.

For everyday hand washing, in areas with abundant water, you can wash your hands with a large amount of water by turning on the faucet, but in areas with water shortage, you cannot wash your hands with large amounts of water.

The present invention, which solves the above problems, adds color to a cleansing or disinfectant made of a transparent basic material, makes the cleaning and disinfecting power of the solvent visible, improves the stability of cleaning or disinfecting the object, and changes the color when the alkaline effect is lost. It is a visible bactericidal liquid that disappears and cleans and disinfects with the minimum amount of liquid.

To solve the problem of whether the cleaning solution or disinfectant solution is properly sprayed, applied, or sprayed on the object to be cleaned or disinfected, color is added to the transparent cleaning solution or disinfectant solution to make it visible. Visible disinfection prioritizes visible color rather than loss of color. Provides liquid.

Visible disinfection liquid, which is a colored transparent detergent and disinfectant, can be visually recognized for its cleaning and disinfecting power, and the color is visible on the surface where it is sprayed, sprayed, or applied, improving the safety of cleaning and disinfecting. there is. Additionally, the colored color becomes colorless when it loses its basicity, making it possible to remove bacteria, viruses, and contamination or perform hygiene management with the minimum necessary amount of liquid.

The present invention is a detergent/disinfectant containing a pH indicator and a basic substance, and is colored on the basic side so that the cleaning and disinfecting power can be recognized. The colored color becomes colorless when it reacts with the acidic side and loses its basicity, with a minimum of It is a visible disinfectant liquid that cleans and disinfects with the amount of liquid.

Known detergents use surfactants as their main ingredient to remove contamination and bacteria, and detergents remove contamination and bacteria through neutralization, and are said to have higher cleaning power than detergents. The disinfectant solution you see mainly uses a neutralizing effect that moves from alkaline to acidic.

The visible component of the disinfection solution is preferably colored by dissolving a pH indicator that reacts with alkalinity in anhydrous ethanol or ethanol and mixing it with a basic substance. It may be dissolved in an organic solvent other than ethanol, or may be dissolved directly in alkaline functional water or an aqueous solution of hydroxide.

The present invention is a visible sterilization solution in which the pH indicator contains at least one selected from the group consisting of phenolphthalein, thymolphthalein, O-cresolphthalein, and their derivatives.

In addition, the basic substance is selected from alkaline functional waters, such as alkaline ion water (electrolyzed hydrogen water), strong alkaline electrolyzed water, and electrolyzed hypochlorous water, sodium hypochlorite, hydroxides of alkali metals and alkaline earth metals, and water. It is an aqueous solution that generates hydroxide ions when dissolved and becomes alkaline, and is a visible sterilization solution consisting of at least one member selected from the group consisting of ammonia, sodium phosphate, and alkanolamine or its derivatives.

In the formulation of a visible bactericidal solution mainly for the purpose of removing bacteria, viruses, and contaminants, a thymolphthalein solution, alkaline functional water with a pH of 10.5 or higher and/or a hydroxide with a pH of 10.5 or higher are preferred, and the colored solvent is UV rays or It is almost unaffected by room temperature, the effectiveness of cleaning and disinfecting power can be seen in a transparent container, has excellent sterilizing power, can sterilize ordinary live bacteria in 30 seconds to 1 minute, is harmless to people, and is friendly to the environment. It provides a visible sterilization solution that can be stored for 1 to 2 years if unopened.

From the viewpoint of sterilizing, eradicating, and disinfecting all bacteria and viruses as a disinfectant, an ethanol concentration of 76.9 to 81.4 v/v% as specified by the Japanese Pharmacopoeia is required, so ethanol, alkaline functional water with pH of 10.5 or higher, and pH of 10.5 or higher are required. One or more types of hydroxides are mixed with a solution of 0.1 w/v% to 10 w/v% of thymolphthalein in absolute ethanol to provide a visible sterilization solution containing an ethanol concentration of 76.9 to 81.4 v/v%. do.

According to the Japanese Pharmacopoeia, less than 76.9 v/v% ethanol, which cannot be labeled as a disinfectant, is used as a detergent; one or more solutions of alkaline functional water with a pH of 10.5 or higher and a hydroxide with a pH of 10.5 or higher; and thymolphthalein in anhydrous ethanol. A solution dissolved at 0.1 w/v% to 10 w/v% is mixed at 1 w/v% to 20 w/v% to provide a colored, visible sterilization solution.

As a virus removal/disinfection agent, from the viewpoint of sterilizing, disinfecting, and disinfecting all bacteria and viruses, an ethanol concentration of 76.9 to 81.4 v/v% as specified by the Japanese Pharmacopoeia is required. However, if the ethanol concentration is 63 v/v%, Since a sufficient sterilizing effect can be expected by removing some bacteria and viruses, as a cleaning agent, mix ethanol with at least one type of alkaline functional water with a pH of 10.5 or higher and a hydroxide with a pH of 10.5 or higher, and add 0.1 thymolphthalein to anhydrous ethanol. A solution dissolved at w/v% to 10 w/v% is mixed to provide a visible sterilization solution containing an ethanol concentration of 63 v/v% or more to less than 76.9 v/v%.

For sterilization and decontamination of water, it is necessary to adjust the ethanol concentration depending on the object or application. Since sufficient sterilization and decontamination can be expected with a concentration of ethanol less than 63 v/v%, as a cleaning agent, ethanol and pH 10.5 are used. A mixture of at least one type of alkaline functional water and a hydroxide with a pH of 10.5 or higher and a solution of 0.1 w/v% to 10 w/v% of thymolphthalein in anhydrous ethanol, and containing an ethanol concentration of less than 63%. , Provide visible disinfection solution.

Since the visible disinfection solution mainly uses a neutralizing action from alkaline to acidic, the pH indicator dissolved in absolute ethanol at 0.1 w/v% to 10 w/v% is used in neutral to basic transparent disinfectants or detergents to determine the pH. When alkaline functional water of 10.5 or higher and one or more types of hydroxide of pH 10.5 or higher are mixed, color is added and it can be used as a visualizing agent and coloring additive.

As a result, neutral to basic transparent disinfectants and detergents commercially available and manufactured can be used as visible detergents and disinfectants, and can be easily mass-produced and distributed, thereby preventing infection.

The visible sterilizing solution may be a non-alcoholic type that does not contain ethanol as a sterilizing or sterilizing ingredient since sufficient sterilizing and sterilizing effects can be obtained with basic substances alone depending on the composition, or it may contain known sterilizing and sterilizing ingredients other than ethanol. You can stay.

Example

As an example that can be most easily supplied and implemented, a solvent in which a pH indicator is dissolved at 0.1 w/v% to 10 w/v% in absolute ethanol is used as a visualization agent, and commercially available, purchased, and manufactured products with a pH of 10.5 or higher are used. By mixing it with an alkaline transparent detergent or disinfectant and coloring it, the cleaning and disinfecting power of the cleaning or disinfection can be recognized. When it is placed in a container such as a transparent spray bottle or mist bottle and cleaned and disinfected by spraying or spraying, the color is obtained. The disappearance time is about 1 to 4 minutes, so the color disappears in the time required for cleaning and disinfection, making it possible to improve the stability of cleaning and disinfection.

In order to color commercially available, purchased and manufactured alkaline transparent detergents or disinfectants between neutral pH 7 and pH 10.5, add 0.1 w/w/w of pH indicator to a strongly basic substance of pH 12 or higher and anhydrous ethanol, as the base is weak as is. A solvent mixed at v% to 10 w/v% is mixed as a coloring additive, placed in an easily transportable container, and cleaned or disinfected.

The pH indicator described above is thymolphthalein or a derivative thereof.

The above-described alkaline transparent detergent or disinfectant with a pH of 10.5 or higher includes at least one type selected from the group consisting of alkaline electrolyzed water, such as alkaline ion water (electrolyzed hydrogen water), strongly alkaline electrolyzed water, and electrolyzed hypohydrogen water, selected from alkaline functional water. It should be included, and selected and mixed depending on the intended use.

It is a detergent/disinfectant containing a pH indicator dissolved in anhydrous ethanol and a basic substance. It is colored on the basic side, allowing the cleaning and disinfecting power to be recognized, and the colored color becomes colorless when it reacts with the acidic side and loses its basicity. , washing and disinfection with the minimum amount of water required is given below as an example of a sterilization solution that can be seen.

Place the visible disinfectant solution in a portable bottle so that you can easily transport it, and when you are concerned, wash and disinfect your hands, skin, or fingers with water.

In the above case, the time it takes for color to disappear is faster the closer the object is to acidity, and since human skin is slightly acidic, the color is lost in an instant by spraying it directly on the hand or skin or rubbing it directly in the hand. In that removal time using the color disappearance time is not required, examples that are considered effective are given below.

When cleaning and disinfecting commercially available paper towels or tissue paper by spraying, spraying, or applying a visible disinfectant solution using a spray bottle or push bottle, the color loss time is approximately 15 to 30 seconds. ·The color disappears in the time required for disinfection, improving the safety of cleaning and disinfection.

If the disinfectant solution visible on wet towels, wet tissues, wet sheets, etc. is dyed by spraying or mordant, sealed, packaged, put into a form that can be easily transported, and cleaned and disinfected, the color loss time is about 30 to 40 seconds. ·The color disappears in the time required for disinfection, improving the safety of cleaning and disinfection.

If the disinfectant solution visible on disinfected cotton or non-woven fabric is dyed by spraying or mordant, etc., sealed, packaged, and cleaned and disinfected in a form that can be easily transported, the color loss time is about 30 to 40 seconds, which is sufficient for cleaning and disinfection. The color disappears in the required time, making it possible to improve the safety of cleaning and disinfection.

As an example of applying the visible disinfectant solution to an object with a small area, put it in a painter's bottle used when painting or a sponge head container used to repel water on car glass, etc., and put it in a form that can be easily transported. If cleansing and disinfection are performed pinpoint with a stable application width in the area where this product is used, the color loss time is approximately 30 to 40 seconds, and the color is lost in the time required for cleaning and disinfection, improving the safety of cleaning and disinfection. do.

As an example of applying the visible disinfectant solution to an object with a large area, if it is put into a spray bottle used for pesticide spraying and used to clean and disinfect protective clothing, walls, floors, and vehicles, the color loss time will be 1 to 2 minutes. To this extent, the color disappears in the time required for cleaning and disinfection, making it possible to improve the stability of cleaning and disinfection.

The use of visible disinfectant solutions is effective for many places, objects, and people that need to be cleaned and disinfected, for example, the interior of a car, walls and items in a hospital, disinfection of protective clothing or temporary tents, examination tables, etc. It can be used to clean and disinfect many plastic items, toilets, toilet seats, bathrooms, kitchens, microwave ovens, refrigerators, kitchenware, glass, floors, toys, personal computers and telephones.

The visible disinfectant solution can be used to clean and disinfect tables, beds, protective clothing, door knobs, toilet seats, bathtubs, etc. by putting it in a spray bottle or mist spray bottle, spraying it on the object, and dissolving it in neutralized water after the color disappears. However, since alcohol remains, if you are concerned, you can use it for cleaning and disinfection by wiping it off or leaving it until it dries.

Iodine-based and colored cleaners and disinfectants use a large amount of water to wash off the color after application, but the visible color of the disinfectant solution reacts with the acid and becomes colorless and neutral, leaving water or alcohol behind, but it can be wiped off. There is no need to wash it again, so it can be used for effective cleaning and disinfection in areas and environments with water shortages.

By visualizing cleansers and disinfectants, it is possible to overcome barriers to small children, language, and education, and clean and disinfect with minimal technology.
