Iodine volts do not turn black when applied to a wound. The main component within iodophor is complex iodine, which is brown or brownish yellow in color, depending on the concentration of iodine. Iodophor is widely used, and can be used on intact skin surfaces, as well as on oral mucosa and wound surfaces, and inside wounds. It is very convenient for disinfection of wounds and the inside of wounds because it is non-irritating and can kill bacteria and fungi, including spores. After disinfection with iodophor, it is not necessary to dry the iodophor with saline or gauze, but only to cover the wound with excipients or gauze.
