Can regular liquor be used for sterilization? How high is the alcohol to be effective?

Many people think of white wine.

It can be used for disinfection, so pour a little liquor on a wound, for example, to achieve disinfection, but white wine sterilization? Or can white wine replace alcohol for sanitization?

First of all, can it be sterilized with liquor?

The amount of liquid is usually about 50 degrees or less, which is well below the alcohol concentration. Only too high an alcohol content will only form a protective film on the surface of the bacteria to enter the bacterial body. White wine, only partially bacterial and viral.

It has a killing effect, so in an emergency, it can be used, but it cannot be replaced by alcohol.

Second, white wine is not a substitute for alcohol disinfection.

Pharmaceutical medicinal alcohols are alcohol solutions at a concentration of 75.

It is strictly equivalent to alcohol and water. This concentration of alcohol has a great osmosis and can pass through the membrane on the surface of the bacteria and enter the inside of the bacteria, which makes the proteins that form the bacteria coagulate, thus killing the bacteria.

People drink beer and liquor is usually signed by alcohol by alcohol. For example, a liquid at 60 degrees is 60 degrees of alcohol. In addition, the composition of the liquid is complex, in addition to alcohols, water contains higher alcohols, organic acids, esters, polyols.

Phenolic components. The action of these ingredients is also very complex, and there is a solution of the effect, so drinking alcohol is very unscientific to replace alcohol killing.

Third, the application and use of liquid disinfection.

White wine does not have a sterilizing effect on dishes and** can also be used in clinical practice. For example, pouring 10 to 50 white wine into your hands, massaging the back, waist, long bed in the bedroom, can promote local blood circulation.

and achieve acne prevention.

purpose. Containing an alcohol content of 25 to 50 degrees, gently wipe the neck, chest, armpits, limbs, hands and feet and can be given to patients with high fever to relieve fever. It is necessary to enter respiratory diseases.

of the peak season. The epidemic is not yet fully controlled. Everyone should take precautions, wear masks in crowded places, and maintain good personal hygiene to prevent problems before they happen.

Strictly speaking, "liquor" does not play a disinfectant role. Only 75% alcohol sterilization is the most effective, and ordinary liquor cannot replace its efficacy. Because the general medical alcohol is 75% concentration, and the high liquor cannot reach this concentration.

The essence of its practical alcohol is to use alcohol to coagulate the proteins in the bacteria, and then kill the cells. Experts say that too high a concentration of alcohol will cause protein coagulation on the surface of bacteria, preventing alcohol from entering the bacteria; Alcohol with too low concentration, even if it can enter the bacteria, cannot have a coagulation effect, and only 75% alcohol is the most effective for sterilization.

It can be used for disinfection, and the alcohol with a degree of more than ten degrees can be simply disinfected, mainly because there is no need for some wine with too pure alcohol content, and it will also cause a series of fire phenomena, so try to avoid it.

Ordinary liquor can not be used for disinfection, and only liquor with a degree above 75 can have an effect, but the liquor on the market does not have such a high degree, and can only choose medical alcohol with an alcohol concentration of 75%.

Ordinary liquor can also be used for disinfection, but its disinfection effect is not as good as that of alcohol. Generally, 65 degree liquor will have an effect and can kill some bacteria.

OK. It has a disinfecting effect of about 65 degrees, and can be used to treat wounds normally, and has a good disinfection effect.

I don't think so. Generally speaking, 85 degrees can achieve the effect of disinfection.

Liquor cannot be used for disinfection, and some can instead promote the growth of bacteria in the wipe area.

This is because the liquor consumed, even if it is more than 60 degrees, its alcohol content is only more than 60%, and the composition of liquor is not only alcohol, but also some polyols, higher alcohols, organic acids, starch, etc. Therefore, the role of liquor is more complex, not only has a certain sterilization effect, but also the starch in it may promote the growth of bacteria. The medical disinfection alcohol is usually made of a 75% alcohol solution with a concentration of 75%, its main components are only water and alcohol, and the alcohol concentration of more than 75% is very penetrating, which can penetrate the surface of bacteria, make the protein coagulation of bacteria, and cause bacteria to lose their activity.

Therefore, liquor cannot be used as a substitute for alcohol sterilization.

The principle of alcohol disinfection is that ethanol absorbs the moisture of bacterial proteins, dehydrates it, denatures and solidifies, thereby killing bacteria. If you use high-concentration alcohol such as 95% alcohol, the bacterial protein will be dehydrated too quickly, and the protein on the surface of the bacteria will coagulate first, forming an envelope, and the ethanol will not be able to penetrate well into the bacteria, which will affect the ability to kill bacteria. At a concentration of 75%, alcohol has the best disinfection effect, which can not only make the proteins that make up the bacteria coagulate without forming an envelope, but also allow the alcohol to continue to penetrate into the interior and completely destroy the bacteria.

If the concentration of alcohol is less than 70%, it does not completely kill the bacteria.

The concentration of liquor we usually drink will not exceed 60 degrees, far below the standard of 75%, and the low concentration will not achieve the purpose of sterilization and disinfection, and the composition of liquor is more complex, in addition to alcohol and water, it may also contain organic acids, esters, higher alcohols, polyols, phenols and other components. The effect of these ingredients on bacteria is also very complex, and they also have a promoting effect and a killing effect, so the use of liquor disinfection is very unscientific and is not recommended.

Therefore, it is recommended to use medical-grade Lifeng 75% ethanol disinfectant for wound disinfection. The disinfection effect is good, and the safety is more assured.

White vinegar has many uses, it can be used for disinfection, pickling food, cooking, dropping a few drops of white vinegar and edible stool oil when cooking rice, the rice made is fragrant and soft, non-stick pan, using white vinegar with dish soap, baking soda, cleaning the kitchen has a miraculous effect, white vinegar has a wide range of use, and the reasonable collocation makes the key backup have unexpected effects and ruined fruits.

Liquor does not play a role in complete disinfection, and the concentration of medical disinfectant alcohol is 75%. The liquor we usually drink, the concentration generally does not exceed 60 degrees, far below the standard of 75%, the liquor only has an orange killing effect on some bacteria and viruses, and the round ridge is chaotic and the composition of the liquor is more complex, and the effect of these components on bacteria is also very complex.

Liquor cannot be sterilized.

The alcohol content of liquor is generally around 50 degrees or below, which is far lower than the alcohol concentration. Only excessively high concentrations of alcohol will form a protective film on the surface of the bacteria and prevent them from entering the bacteria. Baijiu only has a killing effect on some bacteria and viruses, so it can be used in an emergency, but it cannot replace alcohol.

The medicinal disinfectant alcohol used in medicine is a 75% concentration alcohol solution made by strict proportions, and the composition is only alcohol and water. This concentration of alcohol has a great osmotic power, which can penetrate the membrane on the surface of the bacteria and penetrate the inside of the bacteria, causing the proteins that make up the bacteria to coagulate, thereby killing the bacteria.

It cannot be sterilized.

Some people often use liquor to wipe the dishes and chopsticks, thinking that this can achieve the purpose of disinfection. As everyone knows, the alcohol content used for disinfection in medicine is 75 °, while the alcohol content of general liquor is mostly below 56 °, and liquor is different from medical alcohol after all. Wiping the dishes and chopsticks with liquor will not achieve the purpose of disinfection.

Principle of alcohol disinfection.

The scientific name of alcohol is ethanol (C2H5OH), which has a strong penetrating power and can drill into the bacteria, causing the bacteria to coagulate (chemically called denaturation), causing the bacteria to lose their activity and die.

Pure alcohol cannot be sterilized.

The alcohol molecule has two ends, one end is hydrophobic (-c2h5), which can destroy the attraction between hydrophobic groups inside the protein; One end is hydrophilic (-0h), but it is difficult to break the force of attraction between hydrophilic groups outside the protein.

On the other hand, although the water molecule can relax the attraction between the hydrophilic groups of the protein, it cannot destroy the attraction between the hydrophilic groups in its protein even if it burrows inside the bacteria.

Therefore, neither pure alcohol nor water is sufficient to denature the protein within the bacteria, and the protein will lose its physiological activity only if alcohol and water coexist while relaxing the various attractions that maintain the geometry of the protein. Therefore, only a certain concentration of alcohol solution can achieve a good disinfection and sterilization purpose.

Alcohol can play a role in disinfection, and the general industrial alcohol is more than 75%. Liquor has different degrees, generally speaking, the higher the degree, the stronger the disinfection effect, but only for special cases, if the infection has been confirmed, it is best to go to the hospital to do disinfection work, it is not recommended to do self-treatment.

The essence of using alcohol is to use alcohol to coagulate proteins in the bacteria, and then kill cells. Alcohol with too high concentration will cause protein coagulation on the surface of bacteria, preventing alcohol from entering the bacteria, and alcohol with too low concentration, even if it can enter the bacteria, cannot play a coagulation role, and only alcohol at about 75 degrees is the most effective. Therefore, liquor with a concentration of less than 56 degrees cannot play a sterilizing role at all.

The disinfectant effect of liquor is actually not obvious:

1. Among the alcohol, 75%vol of alcohol has a disinfection effect, and other concentrations of alcohol actually do not have a disinfection effect;

2. The general alcohol concentration in liquor is not so high, so the sterilization effect is not obvious;

3. In low-alcohol liquor, with the volatilization of alcohol, there are many nutrients in liquor, which not only cannot play a sterilizing role, but will become a breeding ground for bacteria.

It can be disinfected, but the effect is not very good. The concentration of alcohol used for sterilization and disinfection in medicine is 75, while the alcohol content of general liquor is below 65. Therefore, liquor has a limited disinfection effect on dishes and chopsticks.

It's better to be 75%, if it's too low, it won't work, if it's too high, the protein shell of the virus will coagulate, and alcohol won't enter the virus's body, and it won't kill it, so buy it in a drugstore. Give me a point.

Generally, the alcohol concentration of medical alcohol is 75%, which is sold in pharmacies and clinics, and 100ml is a bottle.

If you go to half of the clinics, you will have ethanol (alcohol) for sale, and the preparation is more appropriate, and if you use alcohol directly, it should be more than 50 degrees.

75 80 degrees alcohol is disinfectant. Volatilization is too fast if it's high, and it doesn't work if it's low.

Medical alcohol pharmacies are all sold, and the disinfection of liquor should be above 60 degrees.

For liquor, it is best to keep it above 50°C. In fact, isn't it more cost-effective to buy alcohol?

1. No matter how many degrees have a certain effect.

No matter how many degrees of liquor it has, it has a certain disinfection effect, but its disinfection effect is worse with the lower the degree of the wine.

The degree of liquor on the market is generally about 50 degrees, or below 50 degrees, far below the standard concentration of 75% alcohol, although the alcohol concentration of liquor has a certain disinfection effect, but it can only have a certain elimination effect on some bacteria and viruses.

Only when the alcohol concentration is 75, the disinfection and sterilization effect is the best, which can enter the bacteria and denature the protein, so that it is inactivated and sterilized, so the concentration of liquor on the market is not very good for disinfection.

2. The higher the degree of liquor, the better the disinfection effect.

The higher the degree of liquor, the higher its alcohol concentration, the higher the alcohol concentration, the better its disinfection and sterilization effect, although it is not as good as the disinfection and sterilization effect of 75 alcohol, but the high number of liquor still has a certain disinfection effect.

There are also a small number of 75% liquor on the market, although this type of liquor is usually not recommended as a drinking product because it is difficult to enter the throat, but the disinfection effect is the best.

Moreover, liquor can be used in diet, which has a good effect on food disinfection, and can also play a role in enhancing flavor and flavor.

However, if the liquor content is compared with 75% alcohol, its disinfection effect is relatively weak, and it has no effect on daily life disinfection, and it is generally not recommended to use liquor for daily disinfection and sterilization.

3. Liquor disinfection can actually be used in many aspects, such as daily items can be wiped with liquor, can also be used to open pores on the surface of human skin, and can also be used for diet.

However, for the role of disinfection, liquor will be more suitable for diet, can be used to marinate fresh meat or other food, can play a good role in preliminary disinfection, but also can improve the taste and taste of meat.

41.Keep away from the fire source: When using liquor for disinfection, it is also necessary to use the principle of fire source, and the alcohol concentration contained in the liquor can also be burned, so in order to prevent danger, it is necessary to stay away from the fire source when using liquor.

2.Try not to spray: Although liquor has a certain disinfection effect, try not to spray it for disinfection when using it, which not only does not play a good disinfection role, but will damage environmental hygiene.
