Including formaldehyde and glutaraldehyde. The principle of such disinfection is that an active alkylating agent acts on the amino, carboxyl, hydroxyl and sulfhydryl groups in the microbial protein, thereby destroying the protein molecules and causing the microorganisms to die. Both formaldehyde and glutaraldehyde can kill various microorganisms. Because they have stimulating and curing effects on human skin and mucous membranes, and can make people sensitized, they can not be used for disinfection of air, utensils, etc., and are generally only used in hospitals. Disinfect or sterilize medical devices, and disinfected or sterilized items must be rinsed with sterile water before use.
