STABLE COMPOSITIONS OF UNCOMPLEXED IODINE AND METHODS OF USE
The present invention is directed to a composition in solution (often, an aqueous solution) which comprises a combination of molecular iodine (I.sub.2) and an acceptable source of iodate (IO.sub.3), and an acid (inorganic or organic), wherein iodide and iodate are present in the composition at a molar ratio of about 0.1 to about 25, the concentration of uncomplexed molecular iodine is a disinfectant, biocidal and/or antimicrobial (depending upon the end use of the composition) effective amount the concentration of acid in the composition is effective to provide a buffering pH in the composition ranging from about 1.5 to about 6.5. Compositions according to the present invention are storage stable for unexpectedly long periods of time (up to about 5 years), and find use as disinfecting solutions, as germicides and/or biocides (e.g. antiviral, antibacterial, antifungal, antispore etc.) for various surfaces and solutions including living and inanimate surfaces and are particularly useful because of their low cost, their reduced use of iodine, their activity (because of the high concentration of free molecular iodine in solution), their reduced environmental impact, their long term storage stability and their reduced toxicity. They also have particular utility in treating food surfaces to retard spoilage, increase useful shelf-life and minimize the human and economic cost of food waste. The compositions inactivate viruses, bacteria (both gram negative and positive), spores and fungi. Compositions according to the present invention may be used and stored in a variety of materials, given the substantial absence of corrosion (non-corrosive) these compositions display. Dental compositions (e.g. preprocedure rinses and other compositions) and methods related thereto are also disclosed.
ANTIMICROBIAL PHASE-SEPARABLE GLASS/POLYMER COMPOSITE ARTICLES AND METHODS FOR MAKING THE SAME
A method of making an antimicrobial composite article, including the steps: providing a matrix comprising a polymeric material; providing a plurality of second phase particles comprising an antimicrobial agent; melting the matrix to form a matrix melt; distributing the plurality of second phase particles in the matrix melt at a second phase volume fraction to form a composite melt; forming a composite article from the composite melt; and treating the composite article to form an antimicrobial composite article having an exterior surface comprising an exposed portion of the matrix and the plurality of second phase particles. The distributing step can employ an extrusion process. The forming a composite article step can employ an injection molding process. The treating step can employ abrading and plasma-treating the article to define the exterior surface.

BIODEGRADABLE GRAFT POLYMERS USEFUL FOR DYE TRANSFER INHIBITION
This application relates to biodegradable graft polymers for use as e.g. dye transfer inhibitors especially in laundry applications. The graft polymers of the invention comprise a polyalkylene oxide polymer as polymer backbone of the graft polymer and grafted side chains obtained from radically polymerizing at least one vinylimidazole-monomer or derivative thereof, and at least one vinyl lactame and optionally further monomers in the presence of the polymer backbone. The inventive graft polymers exhibit among others dye transfer inhibition properties: as they also are bio-degradable. they are especially useful polymers for fabric and home care and cleaning applications to prevent dye transfer. The invention further relates to the production of such graft polymers. Furthermore, the present invention relates to the use of such a graft polymer within fabric and home care products and cleaning compositions, and the use of such graft polymers for inhibiting the dye transfer in laundry applications, and the compositions and products as such containing such a graft polymer.
