Can 95 percent alcohol be disinfected? Is it true that the higher the alcohol concentration, the bet

<> disinfectants should also be people's first choice during the epidemic, especially alcohol, which has become an out-of-stock product. However, most people do not have a great understanding of the use of alcohol concentration, and even some people believe that the higher the concentration of alcohol, the better its disinfection effect. In fact, this kind of thinking is wrong, so many netizens have raised questions:

Can 95 percent alcohol be disinfected? Is it true that the higher the alcohol concentration, the better the disinfection effect?

People with some medical knowledge know that 95% alcohol does not actually have the function of disinfection, it is mostly used to wipe the surface of objects, if it is used in hospitals, 95% alcohol is used to wipe ultraviolet lamps, and in the home it is only used for cleaning camera lenses. So this also makes it clearer that the use of 95% alcohol is generally used for instrument sterilization. However, alcohol with a slightly lower concentration has a certain bactericidal effect.

Just like the 75% alcohol we commonly use in hospitals, it can kill E. coli, Staphylococcus aureus, Candida albicans, Candida albicans, Pseudomonas aeruginosa, etc. within a minute when used under natural conditions. Relatively speaking, its sterilization effect is still very good. That's why, during the pandemic, most people choose to buy alcohol to disinfect their hands or clothes.

However, alcohol, as an inefficient disinfectant, cannot kill the spores in bacteria, so it is often only suitable for general disinfection.

But to a certain extent, this has also changed most people's cognition, making us understand that not all disinfectants are more effective at higher concentrations. So sometimes we should choose to be wary of our stereotypes. When we choose to buy some products, we should also seek professional advice from relevant personnel, so as to avoid choosing some wrong products because of some of our common perceptions, which will lead to some dangerous events, right?

95 percent alcohol can be disinfected, because an alcohol content of more than 75 percent can be sterilized. It is not that the higher the alcohol concentration, the better the disinfection effect, because the right alcohol concentration can achieve the best disinfection effect.

One stop to the end: 75% alcohol is more disinfectant than 95% alcohol?

Of course. Because 95% concentration of alcohol can play a certain role in disinfection, but it will not produce ***.

It can be used for disinfection, because the concentration of alcohol is very high, so it can play a role in sterilization and disinfection, and the effect is also very good.

No, the alcohol concentration at this time is too high to have a sterilizing effect, it will evaporate quickly, and a protective film will be formed.

95% of the alcohol cannot be sterilized, and the alcohol concentration of disinfection is generally 70%. 95% alcohol will make the protein of the bacterial cell wall coagulate, and the protein will form a protective film, and the alcohol cannot enter the cell to kill the bacteria, because the alcohol has an evaporation phenomenon, so even if it is partially evaporated, it can reach a concentration of 70% to disinfect the effect.

95% alcohol cannot be used for disinfection of birds' holes, and the alcohol concentration of disinfection is generally 70%. If it is 95% alcohol, the protein of the bacterial cell wall is coagulated, and the protein forms a protective film, and the alcohol cannot enter the cell and cannot kill the bacteria. Alcohol is contraindicated for disinfection of the eyes and ruptured wounds, and is suitable for ** disinfection.

What are the precautions for using alcohol for disinfection

When using alcohol indoors, wipe it with a cloth cleaning tool such as a towel, and after use, wash it with plenty of water and store it tightly closed, or put it in a ventilated place to dry.

1. It is not recommended to use alcohol to spray and disinfect clothes, etc., in case of open flame or static electricity, combustion can occur.

2. Store alcohol carefully, away from fire, and do not place it in places that are easily accessible to children.

3. Pay attention to ventilation when using alcohol, and stay away from high-temperature objects, and do not contact with open flames. After spraying with high concentration of alcohol, you cannot immediately cook, snort, smoke, etc.

4. Before using alcohol, the surrounding flammable and combustible materials should be cleaned up, and the power and fire source should be turned off when disinfecting the surface of the electrical appliances and the stove, and then wiped with alcohol after the electrical appliances and the stove are cooled to avoid deflagration caused by alcohol volatilization.
