ABSTRACT:
A sustained and controlled release form of iodine is achieved by a complex of polyvinyl alcohol and the iodine characterized by a low water solubility. The polyvinyl alcohol may be reacted to form hydroxylated polyvinyl acetal sponge and the sponge is topically applied as an antimicrobial agent which releases controlled amounts of iodine sufficient to kill germ cells with minimal toxicity to surrounding tissue.
