Abstract:
A water soluble, extended-release chemical formulation, in tablet form, for controlling and preventing precipitation of solids in and transfer of odorous gases from urine and, optionally, for controlling and preventing microbial growth, which consists essentially of:a. an acid salt selected from the group consisting of potassium bisulfate, sodium bisulfate, cupric chloride, and mixtures thereof; andb. from 1.5 to 10% by weight of an extended-release binder comprised of: at least one polyol having an average molecular weight ranging from about 600 to about 20,000 grams/mole; and, optionally, polyethylene oxide,wherein the sum of components a and b total 100% by weight,wherein said chemical formulation is prepared by a method comprising:heating said acid salt to a temperature of from about 100.degree. C. to about 300.degree. C. to melt said acid salt;heating said binder to a temperature of from about 45.degree. to about 70.degree. C.;combining said melted acid salt and said heated binder to form a mixture;pouring said mixture into at least one mold; andcooling said mixture, contained in said mold(s), to form at least one tablet.
