A substance that prevents infection by killing bacteria. Most disinfectants are used on equipment or surfaces rather than in or on the body. Common disinfectants are halogens; salts of heavy metals; organic compounds such as formaldehyde, or alcohol 70%, iodoform, hydrogen peroxide, or ethylene oxide.
