Ethanol, also known as alcohol, has a wide range of uses and can be used as various organic solvents, chemicals, detergents and extractants.
Ethanol can be used to mix liquids, as an adhesive, and as a solvent, hydrogen agent and dehydrogenation agent for cosmetics. Ethanol can also be used as antifreeze, dye and disinfectant. 75% ethanol solution is commonly used for medical disinfection, 95% ethanol can be used for wiping ultraviolet lamps, 40% to 50% ethanol can be used for preventing bedsores, 25% to 50% ethanol can be used for physical fever reduction, and patients with high fever can be scrubbed with 25% to 50% ethanol to achieve the purpose of cooling down.
Because wiping the skin with ethanol can dilate the blood vessels of the patient's skin and increase the heat dissipation ability of the skin, the concentration of ethanol should not be too high, otherwise it will irritate the skin and absorb a lot of water from the epidermis, which is harmful to health.
