So as to achieve the purpose of sterilization. Dilute alcohol does not rush to solidify the protein on the surface of the bacteria but penetrates into the bacteria, and then solidifies the protein in the whole bacteria. If the alcohol concentration is too low, although it can enter the bacteria, it cannot coagulate the protein in the body, nor can it completely kill the bacteria.ħ5% medical alcohol, because the water is mixed with alcohol, the concentration of alcohol becomes thinner.
An excessively high concentration of alcohol will form a protective film on the surface of the bacteria to prevent it from entering the bacteria and it is difficult to completely kill the bacteria. The 95% alcohol concentration is very high. Therefore, only a certain concentration of alcohol solution can achieve good disinfection and sterilization purposes. Only when alcohol and water coexist, and at the same time relax the various attractive forces that maintain the geometric shape of the protein, the protein will lose its physiological activity. Is the higher the purity, the better the sterilization effect? Neither pure alcohol nor water is enough to denature the protein in the bacteria. It can also be used to temporarily sterilize small medical devices with its flame.ħ5% and 95% of medical alcohol are common in pharmacies. It is used to heat laboratory reagents or pharmaceutical preparations after ignition. 95% of alcohol is often used as a fuel for alcohol lamps and alcohol stoves by medical institutions.

This refers to normal skin disinfection, not wound disinfection. 70% to 75% alcohol can be used for sterilization and disinfection, including skin disinfection, medical device disinfection, and iodine deiodination.For example, pour a little 40% to 50% alcohol into the hands during the massage, and evenly massage the patient ’s compressed area to promote local blood circulation The purpose of the formation of bedsores. Prolonged pressure on the back, waist, and buttocks of long-term bedridden patients can cause bedsores. 40% to 50% alcohol can prevent bedsores.But the alcohol concentration should not be too high, otherwise, it may irritate the skin and make the epidermis lose a lot of water. Because wiping the skin with alcohol can dilate the blood vessels of the patient’s skin and increase the heat dissipation capacity of the skin, its volatility can also absorb and take away a lot of heat, so that the symptoms are relieved. Patients with high fever can wipe their body to achieve the purpose of cooling. 25% ~ 50% of alcohol can be used for physical fever.Different concentrations of medical alcohol have different effects. Medical alcohol can be used for human body disinfection, the main purpose is disinfection and sterilization. It can kill a variety of bacteria and viruses, and can also effectively kill new coronaviruses.
Medical evidence shows that when the concentration of ethanol is 75%, the disinfection effect is the best. Medical alcohol is a mixed solution of ethanol and water.

If industrial alcohol is used for skin disinfection, it may be partially absorbed by the skin, leading to poisoning. It can also be used as a cleaning agent and solvent, but it cannot be used for human body disinfection. It can be used in printing, electronics, hardware, spices, chemical synthesis, pharmaceutical synthesis, etc. Due to different manufacturers, its proportion is not the same, generally more than 90%. Industrial alcohol is the alcohol used in industry, also known as denatured alcohol, industrial fire wine. The main component of medical alcohol is ethanol, and the main component of industrial alcohol is methanol. At the time of purchase, the main components of alcohol can be viewed and distinguished. First, we must understand the type of alcohol, alcohol is divided into industrial alcohol and medical alcohol.
