Polyvinylpyrrolidone Iodine PVPIodine

Povidone-iodine is iodophor, used as a topical antiseptic. A 10 povidone-iodine solution contains 1 available iodine, but free-iodine is at 0.1 concentration. Skin exposure causes irritant rather than allergic contact dermatitis. In such a situation however, iodine seems to be the true hapten.
