Disinfectants are chemical substances or agents that are used to destroy or inactivate microorganisms, including bacteria, viruses, and fungi, on surfaces, objects, or living tissues. They are different from antiseptics, which are used on living tissues like skin and mucous membranes, while disinfectants are intended for use on inanimate surfaces or objects.
Disinfectants work by disrupting the cell walls or membranes of microorganisms, leading to their destruction and preventing their ability to multiply and cause infections. They are commonly used in hospitals, healthcare settings, laboratories, and households to reduce the risk of infections and the spread of harmful pathogens.
