What ingredient of wash free hand sanitizer is effective against the new coronavirus? What should I pay attention to when purchasing?
Chlorhexidine cannot effectively inactivate the new coronavirus. Therefore, a disinfectant with chlorhexidine as the main ingredient cannot effectively protect against the new coronavirus.
The new coronavirus is sensitive to ultraviolet light and heat. Lipid solvents such as ether, 75% ethanol, chlorine disinfectant, peracetic acid and chloroform can effectively inactivate the virus at 56°C for 30 minutes. When buying alcohol wash free hand sanitizer, you must pay special attention to the concentration of ethanol on the package. The alcohol content has the most ideal sterilization effect under the condition of 75%. If the concentration is too low, it is not enough to kill the bacteria. When the concentration is too high, the alcohol will first deteriorate the surface protein of the bacteria, so that it cannot enter the bacteria to achieve the sterilization effect.
Many of the hand sanitizers we see in our daily life are ordinary hand sanitizers, and the outer packaging is generally "Cosmetics Product Number", which belongs to the category of ordinary cosmetics, and disinfectant function is mainly to clean;
The other category is disinfection products, "Disinfection Product Number" contains antibacterial, or antibacterial active ingredients.
This hand sanitizer types needs to be put on record for the sanitation and safety evaluation of disinfection products, and only after obtaining the sanitation license can it be produced and sold.
When buying a hand sanitizer with disinfection and sterilization function, look for the products with "Disinfection Product Number" on the package.
