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.
Claims11
A composition comprising acetalized polyvinyl alcohol complexed with iodine, wherein said composition is capable of releasing free iodine in the presence of water.
An antimicrobial product which includes a composition comprising acetalized polyvinyl alcohol complexed with iodine, wherein said composition is capable of releasing free iodine ions in the presence of water.
A method of controlling infection, said method comprising topical application of a product which includes an antimicrobially effective amount of a controlled-release agent, said agent comprising iodine in complex with a polymer selected from the group consisting of polyvinyl alcohol and acetalized polyvinyl alcohol, and said controlled release agent being capable, in the presence of water, of releasing free iodine.
