An agent that kills or prevents the growth of bacteria. This term is generally restricted to agents that are sufficiently non-toxic for superficial application to living tissues. These include the preservatives for eye drops and contact lens solutions. Examples of antiseptics are alcohol, benzalkonium chloride, cetrimide, chlorbutanol, chlorhexidine, hydrogen peroxide, thimerosal (or thiomersalate). Other agents that are too toxic to be applied to living tissues are called disinfectants and are used to sterilize instruments and apparatus. See disinfection; ethylenediamine tetraacetic acid; neutralization; sterilization.
