Disinfectant

Disinfectants are substances which contain active ingredients that kill or inhibit the growth of microorganisms. Disinfectants have to be used at sufficiently strong concentrations and require sufficient application time (more than 10 sec.) Disinfectants commonly used are alcohols (ethanol or isopropanol), hydrogen peroxide (H₂O₂), ozone (O₃), and tinctures of iodine.
