Common antiseptics include alcohol, hydrogen peroxide, benzalkonium chloride, iodine and boric acid. Alcohol, ranging in strength from 60 to 90 percent, is used to disinfect skin before certain medical procedures. Hydrogen peroxide, a common household antiseptic, also cleans and deodorizes wounds. Benzalkonium chloride is found in many first-aid sprays.
Iodine, a rust-colored topical antiseptic, remains active for several hours after application. It is commonly used in surgical procedures. One of the most common ingredients found in creams and eye contact solutions, boric acid treats yeast infections, eye irritation and cold sores. All of these common antiseptics are available in over-the-counter first-aid products.
