Abstract: The present invention is a method for producing solid halogenated hydantoin products using the process of melt extrusion. The form of the products which can be produced includes tablets, briquettes, pucks, dispensers, "designer" forms such as Christmas ornaments, pellets, and granules. The halogenated hydantoin compounds used in the forms contain methylethylhydantoin or an admixture of methylethylhydantoin and dimethylhydantoin. The halogenated hydantoin compositions used to make the forms can also include additives such as solubility modifiers, compaction aids, fillers, surfactants, dyes, fragrances, dispersants, lubricants, mold releases, detergent builders, corrosion inhibitors, chelants, stabilizers, biocides, bromide sources, or oxidizing halogen compositions. The present invention is also the product which is made via the melt extrusion method. The invention also is a method of obtaining an improved feedstock via melt extrusion and the improved feedstock product.
