Medical alcohol is clean and has no other special harm.
Because the composition of alcohol is particularly simple, it is only ethanol, and there are no other impurities. It is better than other ingredients and can be used for cooking.
Medical alcohol is made from starch plants through saccharification, fermentation and distillation, which is equivalent to the process of making wine. However, the distillation temperature is lower than that of wine, the distillation times are more than that of wine, the alcohol content is high, and the output of finished products is high. The ether and aldehyde components other than alcohol are more than that of wine, so it can not be drunk, but it can be used for human medical purposes. It is a product of plant raw materials.
Extended data:
Medical alcohol is mainly used for disinfection and sterilization.
Industrial alcohol can be used in printing, electronics, hardware, spices, chemical synthesis, pharmaceutical synthesis and so on. Can be used as cleaning agent and solvent.
To denature protein, it is necessary to stretch and relax the long chain of curled and spiral protein molecules, and the key is to destroy all kinds of forces that form curled and spiral. Alcohol molecules have two ends, one of which is hydrophobic (C2H5), which can destroy the attraction between hydrophobic groups in protein. One end is hydrophilic (OH), but it is difficult to destroy the attraction between hydrophilic groups outside protein.
