A novel complex of polypyrrolidone, also known as nylon-4, and iodine is disclosed. The complex has biocidal properties exhibiting especially the fungicidal and bactericidal properties of free iodine but not its irritating and toxic properties. The complex may be formed with polypyrrolidone having any physical form, e.g. a powder, film, pulp, fiber or molded article. Bandage material made from nylon-4 fibers and complexed with iodine is a particularly useful form. Ointments and other compositions for topical application may also be made. |
