Can alcohol be used to disinfect hands, and can it be disinfected immediately with alcohol based han

Paying attention to hygiene is what everyone needs to ensure, and some people use ethanol for hand washing and disinfection The actual effect will be stronger, and hand washing and disinfection need to be often disinfected with medical alcohol? What are the benefits of using ethanol to sanitize your hands?

1. Do you need to use medical alcohol to disinfect your hands and disinfect your hands?

It is not recommended to use it often.

1. Ethanol with a high concentration will produce a protective film on the surface of the germs, preventing them from entering the body of the germs and unable to completely kill the germs;

2. If the alcohol content is too low, although the germs can be entered, the protein of the body cannot be coagulated, and the germs cannot be completely killed. Ethanol has some benefits for **. Ethanol is very volatile, and when it evaporates, it will also bring water on the ** and make it dry.

Ethanol with a higher concentration value has a strong ability to dissolve, and in addition to dissolving facial vegetable oils, it will also destroy the existing water film, making it more and more sensitive.

2. What are the benefits of using ethanol to wash hands and disinfect your hands?

There are various types of ethanol, but alcohol and isopropyl alcohol are generally only used as disinfectants. These two chemicals can reasonably kill a variety of germs, viral infections, malaria parasites and bacteria, and the toxicity to humans is relatively low. Ethanol is the most common way to disinfect **, usually in the form of a liniment or a suspicious gel.

If you wash your hands with ethanol, you can remove germs from your arms, and you can maintain a certain amount of hygiene and hygiene, but you need to pay attention to the frequency of hand washing and disinfection with ethanol is not too much, and it is generally recommended to do it once or twice a day.

3. Ethanol hand wiping and soap hand washing and disinfection.

Soap. Removing stains, disinfection and sterilization is the key purpose of hand sanitization, and ethanol only considers its sterilization effect, because ethanol can not reasonably remove some wastes adhered to the ** fine gaps, such as dust, soil, bloodstains, etc., and soap can not only sterilize and disinfect, but also reasonably remove the tiny dirt of the arm, therefore, it is generally recommended to use soap to wash hands and disinfect stronger.

4. If you use medical alcohol to disinfect your hands, the appropriate process is as follows:

1.Under the specific guidance of a specialist, the ethanol dilution, or immediately go to the hospital to purchase the diluted ethanol.

2.Wet your hands with tap water thoroughly and apply to ethanol.

3.Close the fingers of both hands, and then rub the palms of both hands repeatedly to clean the palms of the hands.

4.Stretch out the fingers of both hands, then turn the palms of the two hands against each other, and then rub the fingers of the two hands back and forth with each other, so that you can clean the inside of the fingers.

5.Rub the thumb of the hand that is straight with one hand and the other hand holding the straight hand back and forth, and then rub the fingers alternately, so that you can clean between the fingers of the thumb.

6.Once you've finally cleaned all your arms, clean them up with cold water.

Alcohol can be used to wash hands, but the alcohol content must reach 70% or more to disinfect.

Medical alcohol can be sterilized, but industrial alcohol cannot, and the alcohol content and use of the two should be distinguished. It's best not to use it casually.

Alcohol itself has a disinfecting effect and can be used to wash hands.

Use the prepared medical alcohol for disinfection, if there is really no medical alcohol, you can only use liquor for temporary emergency.

Absolutely. However, I personally think that the effect will be better if you wait for half a minute, and the volatility of alcohol is very strong. After waiting for half a minute, it is estimated that I will be finished volatilizing.

After disinfection with alcohol-based hand sanitizer, the bacteria on the hands have been removed, and washing off these disinfectants with water is to avoid the damage of alcohol-based hand sanitizer to the hands.

Hand washing is one of the most direct and effective ways to reduce hand bacteria and viruses, and proper hand washing is the key. Proper handwashing means washing hands with running water, soap or hand sanitizer, rubbing each hand for more than 20 seconds, and ensuring that the palms, fingers, backs of hands, fingers, nails, wrists, etc. are cleaned. When it is not convenient to wash your hands, you can use a hand sanitizer with 75% alcohol for hand sanitizer.

Many hand sanitizers claim to be alcohol-free (for fear of hand injury or other flammable hazards), but in fact, medicine has given the official answer that it is 75% ethanol.

Alcohol can achieve the disinfection effect.

Indeed, some alcohol-based hand sanitizers can easily cause dryness, peeling, and even redness. Therefore, at this time, it is recommended that you choose a hand sanitizer that contains moisturizing and moisturizing ingredients.

So the next question is, the higher the alcohol concentration, the better the disinfection effect?

Wuhan University Medical Center.

Yang Zhanqiu, a professor at the Institute of Virology, said that it is not that the higher the alcohol concentration, the better the disinfection effect. High concentrations of alcohol will cause the proteins on the surface of the virus to coagulate quickly, but because the speed is too fast, the alcohol will not be able to continue to penetrate inward, and for some viruses, its interior is still "alive", so it is not effective. When the alcohol concentration is 75% lower, it also affects the ability to kill the virus due to reduced permeability.

Moreover, 75% of alcohol is associated with the osmotic pressure of virus-infected cells.

Similarly, before the protein on the surface of the virus is denatured, it can gradually and continuously penetrate into the inside, so that all the proteins of the virus are dehydrated, denatured and coagulated, and finally achieve the purpose of killing the virus, especially the coronavirus.

Disinfection has a process, and immediate cleaning will affect the sterilization effect.

Is it still sterilizing with alcohol-based hand sanitizer and washing it immediately? I think that when you use alcohol hand sanitizer to disinfect and clean, this should have no sterilizing effect.

Frequent hand washing is something that everyone needs to do, and some people say that washing hands with alcohol will be better, especially during this period of the epidemic, many people will choose to disinfect with alcohol, so do you need to use alcohol to disinfect your hands frequently? Let's take a look.

1. Hand washing does not need to be disinfected with alcohol frequently.

2. Because too high concentration of alcohol will form a protective film on the surface of bacteria, preventing it from entering the bacteria, it is difficult to completely kill the bacteria;

3. If the alcohol concentration is too low, although it can enter the bacteria, it cannot coagulate the proteins in the body, and it cannot completely kill the bacteria. Alcohol has some benefits for the skin. Alcohol is very volatile, and when it volatilizes, it will also take away the water on the **, so that the ** is dry.

Alcohol with a higher concentration has a strong decomposition ability, and while decomposing facial oil, it will also destroy its own water quality membrane, making it fragile and sensitive.

If you wash your hands with alcohol, you can remove germs from your hands and protect your personal hygiene, but you need to pay attention to the number of times you wash your hands with alcohol, and it is generally recommended to wash your hands once or twice a day.
