The use of alcohol disinfection every day is not very harmful to objects, the main harm is to the human body, and the use of alcohol every day is the most obvious harm to the skin.
Because alcohol has a very strong penetrating power, it can penetrate into cells, and in the long run, it is easy to lead to protein coagulation and denaturation, which leads to dehydration, and slowly the skin will lose its elasticity.
Secondly, alcohol is also very volatile, which takes away heat at the same time, but also takes away the moisture of the skin, in the long run, it will make the skin's moisturizing effect and immune effect greatly reduced, the skin appears dry, oil secretion, enlarged pores and other phenomena.
Therefore, if you use alcohol to disinfect the skin every day, the harm is still relatively obvious, so it is not recommended to apply alcohol to the skin every day.

Long-term disinfection with 75% alcohol may cause the resistance of the bacteria to it, thus reducing or even losing the sterilization effect and leading to unnecessary errors, the disinfection of the instrument can be used alternately with benzalkonium bromide, and the direct use of the human body can be used alternately with iodine wine.
Industrial alcohol cannot be used for the disinfection of the human body, because methanol will cause poisoning, and some of it will be absorbed for disinfection, and it can lead to blindness and even death after poisoning.
Disinfection mechanism. To denature proteins, it is necessary to stretch and relax the long chains of protein molecules that are curled and helixed, and the key is to destroy the various forces that form curls and helixes.
The alcohol molecule has two ends, one end is hydrophobic (-ch), which can destroy the force of attraction between hydrophobic groups inside the protein; One end is hydrophilic (-OH), but it struggles to break the force of attraction between the hydrophilic groups on the outside of the protein.
On the other hand, although the water molecule can relax the attraction between the hydrophilic groups of the protein, it cannot destroy the attraction between the hydrophilic groups in its protein even if it burrows inside the bacteria.
Therefore, neither pure alcohol nor water is sufficient to denature the protein within the bacteria, and the protein will lose its physiological activity only if alcohol and water coexist while relaxing the various attractions that maintain the geometry of the protein. Therefore, only a certain concentration of alcohol solution can achieve a good disinfection and sterilization purpose.
