The main component within iodophor is complexed iodine, which is brown or brownish yellow in color, depending on the concentration of iodine. When iodophor is applied to a wound, the iodine binds to the fat particles and the wound then turns black. Iodophor is widely used and can be used on intact skin surfaces, as well as on oral mucous membranes and on the surface and interior of wounds. Iodophor is able to kill bacteria and fungi, including budding spores, etc. Because iodophor is not irritating, it is very convenient for disinfection on wounds and inside wounds. Although iodophor can darken wounds, it does not cause hyperpigmentation. After disinfection with iodophor, it is not necessary to dry the iodophor with saline or gauze, but only to cover the wound with a dressing or gauze.
