Why The Alcohol Content Of Alcohol Wipes Is 70%~75%

Nowadays, alcohol wipes are also very common in our lives. They can not only sterilize but also bring convenience to our lives and are very clean. And according to the different concentration of alcohol, its use is also different, and the alcohol used for disinfection is 70%-75% alcohol, so why is it between this data?

This is because too high a concentration of alcohol has a great ability to coagulate protein, but it coagulates the protein on the surface of the bacteria at once, forming a hard film. This hard film prevents alcohol molecules from penetrating further into the bacteria, but instead protects the bacteria from death. If the alcohol concentration is too low, bacteria can enter, but the protein in the body cannot be coagulated, and the bacteria cannot be completely killed. So between this data, too, the sterilization rate is also very high.
