Some questions about alcohol disinfection spray

1. Why can alcohol be used for disinfection?

Alcohol (ethanol) is one of the commonly used disinfectants in medicine and the most widely used disinfectant. It is soluble in water and has a certain degree of fat solubility. The mechanism of ethanol sterilization and virus killing is: its fat solubility can destroy the biological membrane composed of biological phospholipid bimolecular, causing the structure and function of the biological membrane. The higher concentration of ethanol can destroy the "order" of the membrane structure, thereby destroying the function of the membrane, leading to the death of "membrane" microorganisms.

2. Can medical alcohol be used for air disinfection?

Ethanol is a widely used clinical disinfectant, but since its killing relies on high concentration, it can only be used for in vitro disinfection. For example, hand disinfection and surface cleaning and disinfection. Specifically, in the home disinfection process, 3 parts of pure ethanol and 1 part of water can be used to prepare 75% ethanol as the basic hand wipe, or spray or wipe to clean and disinfect the surface of the object. Of course, it is much more convenient to use ethanol to wipe your hands than to wash your hands with soap. Because ethanol will evaporate quickly, there is no need to dry the hands, which is convenient and reduces possible pollution during the drying process.

3. Is the higher the alcohol concentration the better?

To achieve the effect of destroying 99% of , the content of ethanol is usually higher than 60%. Studies have found that a concentration of 75% to 80% can kill most and enveloped in a few seconds, but it is not effective against l spores. Among them, 75% ethanol is a commonly used concentration, and it is most widely used in hospital systems, scientific research laboratories and other occasions where disinfection is required. However, 95% of the high-concentration ethanol has a disinfecting and effect, but it is not as good as the dilute ethanol. This is because the high-concentration ethanol will condense the protein on the surface of the to form a layer of dura, which protects the from further infiltration. So 75% ethanol is the most ideal choice.

4. The disinfectant alcohol spray is flammable. What should I pay attention to when using it?

The flash point of 80% ethanol is 19°C, so care must be taken during use, transportation, and storage, and open flames and smoking are forbidden. When using ethanol, pay attention to avoiding open flames, and it is not advisable to spray too much on a large area to avoid fire.
