Is it necessary to wash hands with water after disinfecting hands with alcohol?

You don't need it, because alcohol itself has a good volatile effect, and it will volatilize itself, and if you wash it with water, it will be polluted again, and it will be disinfected in white.

If there is no wound, you can wash it with water, but if there is a wound, then do not wash it with water, as it will cause secondary infection.

There is no need, alcohol will volatilize on its own after disinfection!

There is no need, the alcohol will volatilize and will not leave a smell.

There is no need, the alcohol volatilizes on its own.

It depends on the situation, if it is in daily life, you have to wash it, because there is a peculiar smell; If you disinfect it and use it for experiments, you can't wash your hands.

There is no need, alcohol evaporates quickly.

There is no need as long as you are not afraid of the smell of alcohol.

What do you do with alcohol disinfection; If you want to live in normal life, you don't need it; If you have surgery, do not wash it with water.

It is better to wash it with warm water.

No need! Alcohol volatiles.

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.

1.Commonly used hand sanitizer: Generally, it should be done after washing hands with running water soap, and hands should be soaked in 75% ethanol or iodine volt, or chlorhexidine solution, peracetic acid solution, chlorine-containing disinfectant solution (containing 500mg of effective chlorine 1000ml), etc.

2.Pay attention to washing hands with disinfectant: When wiping hands with disinfectant, apply it evenly, and pay attention to fingertips, finger seams and other parts that are not easy to reach.

Wipe your hands and let them dry. Soak your hands with disinfectant for at least 1min, and soak in Xinjieer for more than 3min. The disinfectant should be prepared according to the specified concentration, replaced daily or half a day, and the soaking basin should be washed in advance.

Rinse your hands with soap before using disinfectant and dry them before using disinfectant.

After wiping your hands with ethanol disinfectant, if you wash with water, it will not have the effect of disinfecting, so you can't wash it with water.

1. Washing hands 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.

1. Wet your hands first, then rub them with alcohol, and wash them off with water, generally the ethanol with a higher concentration will produce a protective film on the surface of the bacteria, preventing them from entering the body of the bacteria, and the bacteria cannot be completely killed;

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.
