How to choose 75% alcohol wet wipes?

Academician Li Lanjuan said that alcohol with a concentration of about 75% can kill the new coronavirus. Alcohol products such as alcohol wipes, alcohol sprays, and alcohol hand sanitizers have broken out in the market. The products are also dazzling and overwhelming. Alcohol products can be said to be the most sought-after items besides masks. Among them, because alcohol wet wipes are convenient and safe to carry (alcohol spray has safety hazards), they can not only wipe hands, but also wipe hard surfaces of objects, which are particularly popular. It is precisely because the demand for 75% Alcohol Wet Wipes has risen that fakes have begun to be everywhere.

First of all, the alcohol used by some manufacturers is fake alcohol. The fake alcohol is not ethanol but 95% methanol. Methanol not only has no disinfecting effect, but also has certain toxicity. The way to distinguish between true and false is to smell it. Fake alcohol has no smell of alcohol, but it can be ignited.

Alcohol is divided into: medical alcohol, industrial alcohol, and edible alcohol. Medical alcohol must comply with the "Chinese Pharmacopoeia" and can be used in the pharmaceutical industry. Take alcohol wipes as an example, look for medical alcohol when buying, don't step on the pit!

The reason why 75% alcohol wet wipes can be disinfected is because the alcohol can absorb the moisture of bacterial protein, make it dehydrated, denatured and coagulated, thereby achieving the purpose of sterilization. Experiments have shown that if the alcohol concentration is too high, a protective film will be formed on the surface of the bacteria, which cannot enter the bacteria body and it is difficult to completely kill the bacteria; if the concentration is too low, although it can enter the bacteria, it cannot coagulate the protein, nor can it. Kill the bacteria completely. 75% alcohol wet wipes can gradually and continuously penetrate into the bacteria before the surface protein of the bacteria is denatured, so that the bacteria protein is dehydrated, denatured and solidified, and finally achieves the sterilization effect. Therefore, when choosing a product, you must choose a true 75% alcohol wet wipes with a sufficient alcohol ratio.
