from the wound. The dressing is thin, and comes sandwiched between backing papers, from which it is peeled off. Once applied directly to a recently cleaned wound it has the ability to absorb some

or blood from the wound. As the iodine is used up, the dressing loses colour and becomes white. It is typically held in place using gauze and then bandage material. The polyethylene glycol provides a moist environment allowing the iodine to reach the wound. After a few days the dressing has a tendency to dry out, and must be changed often. Left on too long, it can engage with wound tissue and wound secretions when drier, and be more difficult to remove. This tendency to adhere to

. E. Vallin had proposed the antimicrobial property of iodine in 1882. Until at least the 1950s, it was usual to see tinctures of iodine as an essential component of the medicine cabinet. Local pain, irritation and orange-brown staining of the skin, however, limited its use. Later formulations were developed which were less painful and their use has become widespread. With the exception of the United States, Inadine has been available in several countries since the 1980s. It was previously made by
