What is the concentration of medical alcohol?

Medical alcohol has a wide range of uses. It can achieve the purpose of sterilization and disinfection. We know that the concentration of medical alcohol is generally 75%. In addition to this, there is also 95% medical alcohol. The effect of 95% is a little stronger, but they can both denature proteins, so they can have a good bactericidal effect. Generally speaking, if your family needs to prepare medical alcohol, you can choose one with a concentration of 75%.

95% alcohol is often used to wipe UV lamps. This type of alcohol is commonly used in hospitals, but at home it is only used to clean camera lenses.

75% alcohol is used for disinfection. This is because too high a concentration of alcohol will form a protective film on the surface of the bacteria, preventing it from entering the bacteria, making it difficult to kill the bacteria completely. If the alcohol concentration is too low, it can enter the bacteria but cannot coagulate the protein in their bodies, nor can it completely kill the bacteria.

40% to 50% alcohol can prevent bedsores. The back, waist and buttocks of bedridden patients may develop bedsores due to long-term pressure. If you pour a little 40% to 50% alcohol into your hands and evenly massage the pressure areas of the patient, you can promote local blood circulation and prevent the formation of bedsores.

25% to 50% alcohol can be used to physically reduce fever. Patients with high fever can use it to rub their bodies to reduce temperature.

For patients with fever, we usually use 25% to 50% alcohol for physical cooling. If you don't have this concentration of alcohol at home, it doesn't matter. We can use white wine. Generally speaking, most of the white wine at home is 30 to 40 degrees, so it is a good choice for physical cooling.

In short, the concentration range of medical alcohol is very wide, and different concentrations have different effects. You should also pay more attention when using it. You can choose the appropriate concentration according to your needs. It is recommended that friends who want to buy alcohol for their own use should choose the appropriate concentration. For example, for friends who want to use alcohol to promote blood circulation, if you use 75% alcohol, it may irritate the skin, and its effect is too strong and is not suitable for use.
