disinfectant

 [dis″in-fek´tant]
1. freeing from infection or infection-producing organisms.
2. an agent that does this. Heat and certain other physical agents such as live steam can be disinfectants, but in common usage the term is reserved for chemical substances such as mercury bichloride or phenol. Disinfectants are usually applied to inanimate objects since they are too strong to be used on living tissues. Chemical disinfectants are not always effective against spore-forming bacteria.

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).
