  • Patent number: 4994280
    Abstract: A stable concentrated iodophor composition is useful in aqueous solution for control of microorganisms in the therapeutic and prophylactic culture of aquatic animals such as fish, reptiles, and amphibians. It is effective against bacteria, fungi, viruses, algae and the like in very dilute solution while being non-toxic to higher animals. Its biocidal action is due in large measure to the action of iodine that is slowly released into the water. The solution has low-foaming properties to enable its use with water systems having moving water in fountains, filters and bubble aerators. The composition includes phosphoric acid, ethylene glycol monobutyl ether, and two iodophors, a first iodophor formed by mixing iodomethane with a quaternary ammonium surfactant and a second iodophor formed by heating iodine with either an alkyl phenoxyl polyether alcohol or oleic acid sulfonate.

  • Patent number: 4904480
    Abstract: 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.
