Hydrogen peroxide is generally used for medical wound disinfection, environmental disinfection and food disinfection. It has strong oxidizing properties, which can cause lipid peroxidation, and is also corrosive, and can cause a burning sensation when sprayed on the skin, which may directly harm the human body, so it should not be used for disinfection at home, nor should it be sprayed on clothing, hair and shoe soles. The new coronavirus is sensitive to ultraviolet light and heat. 56°C for 30 minutes, ether, 75% ethanol, chlorinated disinfectants, peroxyacetic acid and chloroform and other lipid solvents can effectively inactivate the virus, so it is more appropriate to use the above items for disinfection, but attention should be paid to the concentration and the environment in which they are used to avoid posing a threat to human safety.
