p-1440 RADIATION COMPATIBLE IODINE FORMULATION ABSTRACT OF THE DISCLOSURE A germicidal iodine-containing composition includes iodine, an iodophor, cupric ions and nitrite ions in an aqueous base. Iodide ions which form in the composition during radiation sterilization or prolonged shelf life are oxidized back to iodine by the cupric ions in a pH dependent reaction which consumes hydrogen ions formed concurrently with the iodide ions. Cuprous ions formed during the oxidation are spontaneously cycled back to cupric ions by traces of air present in the composition. The composition may include nitrite ions to augment the conversion of cuprous ions back to the cupric form.
