What is the principle of alcohol disinfection?
Alcohol disinfection agent commonly used in life is called External alcohol, English is Rubbing alcohol The composition is usually Ethanol(Ethanol), or Isopropyl(Isopropanol).
Regardless of the ingredients, the working principle of sterilization and disinfection is the same.Ethanol or isopropanol can break the protein in the bacterial or virus outer membrane by binding to the external membrane of the virus or bacteria, and then the ethanol or isopropanol will be combined with these proteins to make them transgender solidification, bacteria or bacteria or bacteria or bacteria orThe virus will die quickly after losing these proteins.This is the principle that alcohol can quickly sterilize and disinfect[1]Essence
The most important thing is that alcohol disinfection can kill the new crown virus.The following is a video released by Huck Institutes of the Life Science, the University of Pennsylvania.
What kind of alcohol is used for disinfection alcohol?
Topical disinfection alcohol usually uses ethanol or isopropanol as the base.
In the past, ethanol, as an economic chemical raw material, was the main component of external disinfection alcohol.
Later, people found that isopropanol has better disinfection than ethanol, and is less toxic.It is not easy to be contaminated by the oxide acetaldehydehdehyde of ethanol.
Therefore, alcohol instead of ethanol has become the main disinfection alcoholic substrate[2]Essence
How to choose 95% alcohol and 75% alcohol?
Division of disinfection alcohol will be divided into different levels according to the active ingredients in the solution, that is, the content of ethanol or isopropyl, the maximum concentration is nearly 99.96%.Because pure glycol or ethanol has high water absorption, water will be absorbed from the air.Therefore, 100%purity alcohol cannot be obtained.
The most commonly used in life is the 75%concentration of alcohol solution for disinfection for daily life.Because the 75%concentration of disinfection alcohol is similar to the osmotic pressure of bacterial or virus cell membranes, thereby can more effectively destroy the cytosone and penetrate into the interior of the bacteria or virus, so that the protein dehydration degenerates solidification and eventually death, thereby achieving the role of sterilization and disinfection[3]Essence
Another commonly used concentration is 70%, because this concentration of alcohol solution, in daily life or sterilization and disinfection capacity for ordinary medical equipment and 75%concentration alcohol solution, but its volatility is more than 75%concentration alcoholic alcoholic alcoholMany small, this directly reduces the risk of combustion and inhalation of the human body in the process of use and storage.[3]Essence
The other is the 95%concentration of alcohol disinfection solution.Usually it is more suitable for the precision industry, an ideal solvent and detergent for water-sensitive items.Because they use this concentration of alcohol solution, they can quickly volatilize without bringing unnecessary moisture to the items.Applicable objects include computer technicians, precision medical equipment manufacturers, printed circuit board manufacturers and welding technicians, etc.[3]Essence
How to use medical alcohol correctly?
It is more convenient to buy medical alcohol, and online malls such as store shelves or Amazon can be purchased.
According to different concentrations, there are certain differences in medical alcohol of different levels of medical alcohol.
- The concentration is less than 75%of the medical alcohol.You can use cotton slices to dip it directly and wipe it on an object or skin surface you need to use.It can also be pushed into the surface of an object that needs to be disinfected, or the human limbs and trunk.It cannot be sprayed on the face, and the medical wine essence is used in a good ventilated environment.
- Alcohol solutions with higher than 75%, especially higher than 90%concentration, must be diluted after a certain proportion in daily life, and must be sealed in time after use, and stored in a shade.
Which alcohol disinfection is toxic?
In some industrial disinfection of alcohol production, there will be some toxic substances that are toxic, such as methamol (Methanol) or 1-Propanol.
Methanol, also known as wood alcohol Wood Alcohol, will be absorbed by the human body and produces toxicity through the skin.The possible adverse consequences include nausea, vomiting, headache, blurred vision, permanent blindness, epilepsy, coma, permanent nervous system permanentDamage or even death.
Disinfection of alcohol containing 1-propane, when it penetrates into the human body, the central nervous system suppression phenomenon such as blurred consciousness, pulse, and slow breathing may occur, which will cause adverse reactions to death.
At the same time, the FDA also warned that it is not safe to have microbial pollution or a hand-tohed solution for merchants.
American Food and Drug Administration ( U.S.FOOD & Drug Administration), These ingredients have been listed as ingredients that must not appear in Hand Sanitizer, and listed hand-toiler products that have been detected on their websites.It is recommended that buyers do not use these that may endanger health that may endanger health.Alcohol disinfection product[4]Essence
What are the precautions for using alcohol disinfection?
- Do not mix with similar reagents such as bleaching agents, otherwise toxic gases that damage the lungs will be released, which will cause burning sensation in the eyes, throats, and lungs[5]Essence
- Do not use disinfection alcohol near Minghuo, because alcohol is volatile, after use, it will quickly volatilize into alcohol gas to enter the air.When the alcohol gas reaches a certain concentration in the air, it encounters the fire.[6]Essence
- Do not use disinfection alcohol in an environment with poor circulation or air circulation, because of the volatility of alcohol, in such an environment, it will cause the concentration of alcohol to increase the concentration of alcohol and gas in the air.It is stimulus and also increases the probability of the fire.[6]Essence
- As a disinfection agent, it cannot be used on the surface of wood and leather objects, because ethanol or isopropanol in alcohol reacts with these materials, resulting in degeneration or fading of materials.Wood or leather cleaner[5]Essence
- Do not use alcohol on the skin on wounds or abnormal conditions.For skin wounds, appropriate amounts of alcohol can have the effect of sterilization and disinfection, but if it is used in large quantities, it will stimulate the skin at the wound, lead to more serious damage and delay the healing time.For abnormal conditions such as allergies, the use of alcohol will increase allergies.Therefore[6]Essence
- Edit, although this seems to be almost impossible, ethanol or isopropanol itself is a colorless transparent liquid, so when it is stored in inappropriate places, it is really easy to release it and drink it.( National Capital Poison Center) It means that even a small amount of external alcohol is poisonous when ingesting, so disinfection alcohol should be stored in the right place, especially in places where children cannot touch, so as not to occur unexpectedly[7]Essence
- Avoid contact with the eyes and other parts, alcohol has strong irritation to these parts, which will cause burning pain and damage the surface of the eyeball.Therefore, in the process of picking and use[8]Essence
The higher the alcohol concentration, the better the disinfection?
According to the sterilization and disinfection mechanism of alcohol, when the concentration is about 75%, it is similar to the osmotic pressure of the bacterial virus outer membrane, which can facilitate alcohol to infiltrate the interior of the bacterial virus, so that the protein dehydration and degeneration solidify, and eventually kill bacteria and viruses.
And some experts said, in fact 70% concentration alcohol has better sterilization and disinfection effect Because they contain more water, which helps disinfectants to dissolve slowly and kill harmful substances more thoroughly.
When the concentration gradually increases, because the protein in the outer membrane of the bacterial virus is dehydrated and solidified too quickly, the surface of the bacterial virus is formed to form a protective film to prevent the alcohol of alcohol from penetrating into the bacterial virus.Bacterial virus.
On the other hand, because of the high concentration of alcohol, it is also more volatile, which leads to the use of sterilization and disinfection effects after use.[5]Essence
Nine household methods of medical alcohol
1.Daily disinfection
Frequently used mobile phones, keyboards, and mouse devices can easily remain and breed bacteria.You can use cotton slices to dip the disinfection of alcohol to disinfect and disinfect them.They can keep them clean without damaging equipment.
When cleaning, it is necessary to pay attention to using more than 70%of the concentration of disinfection alcohol.The too low concentration contains too much water, which will affect the volatility of the cleaner, resulting in the water residue on the surface of the electronic device, and the hidden dangers of damage function.
2.Kitchen removal of stains
The use of disinfection alcohol solutions to disinfect the surface or ground of kitchenware such as granite, quartz, etc., is a non-toxic and harmless family cleaning method.
When cleaning, be careful not to mix with another cleaner (bleaching powder) commonly used in the family, because these two ingredient mixing will produce toxic gases[5]Essence
3.Shoes demented
The odor in the shoe is caused by sweat from the breeding of the bacteria of the food.Therefore, spray the sterilized alcohol into the shoes, and then wait for the liquid to volatilize the odor in the shoes.Regular cleaning can avoid the breeding of the bacteria again.
The concentration used is daily concentration, that is, 70%or 75%, too high concentration is not conducive to sterilization[5], Too low concentration, too much water, is not conducive to volatilization and dryness, and the sterilization effect is also reduced.
4.Toothbrush disinfection
Toothbrushes are used to clean the mouth, but the toothbrush itself, because of the dense brushing hair, provides a favorable place for bacterial breeding, so regular disinfection and cleaning of the toothbrush is a necessary procedure to make it better.
When cleaning with disinfection alcohol, you can soak the toothbrush in about 70%of alcohol, about 30 seconds, and then rinse it with water to complete the disinfection work.
When used, a liquid alcohol solution should be used instead of gel-type disinfection alcohol to avoid gel remains on the toothbrush, and then enters the oral cavity or even enter the digestive system.
5.Remove insect repellent
Compared with insecticides, the use of sterilized alcohol can be used as a small toxic method for indoor plants to remove pests.You can use cotton swab dipped in alcohol to wipe the insects to prevent the small-scale outbreak of crawlers.
The concentration of alcohol adopted is more suitable for about 70%.Excessive concentration may damage plants while eliminating pests.
6.Homemade ice bags
The 70%concentration of sterilized alcohol and water are mixed with a sealing bag at a ratio of 1 to 1, and put in the freezer of the refrigerator to quickly get homemade ice packs.It can be used when using a piece of cloth when using it.
7.Eliminate ink juice
Wipe the ink stains splattered on the clothes with disinfection alcohol, and quickly clean it before it volatilizes, which can be effectively removed.
When cleaning, it should be used with a concentration of about 70%.Excessive concentration may stimulate the textile fiber of the clothing to damage the clothing.At the same time, if ink stains are splashed on leather fabrics, alcohol should not be used as a cleaner, because it will damage the surface of the leather and damage the fabric [5] Essence
8.Car glass defrost
Sterilization alcohol can quickly remove the frost on the car glass, mix the commonly used disinfection alcohol with the family and tap water at a ratio of 1 to 1 or 2 to 1, spray it on the frost, they will quickly dissolve and restore it into liquid flow.
However, because alcohol has a certain destructive material such as paint and other materials, for the surface of the car that has not been waxed, you should pay attention to avoid the car shell when spraying.
9.Disinfection of clean sponge
After cleaning the sponge, many impurities dirt is often piled up in its pores, which is very easy to breed bacteria.If disinfection is made from time to time, the surface of the wiping may be dirty after wiping with a clean sponge.
Disinfecting alcohol can disinfect the cleaning sponge well, soak the cleaning sponge in the sterilized alcohol solution, remove it about 10 minutes, and rinse it with water.
It should be noted that when disinfected sponges, you can use 75%or one-time disinfection alcohol solution.Keeping enough water can be more conducive to disinfection.
At the same time, if the cleaning sponge dipped in other disinfectants such as bleaching agents, it must be removed after cleaning the water before disinfection with alcohol.Toxic gas[5]Essence
