ABSTRACT:
A substantially sulfur-free ammonium thiosulfate containing product can be produced by spray drying an aqueous solution containing ammonium thiosulfate and effective stabilizing amounts of both a carbonate component and a sulfite component under effective conditions to provide a substantially sulfur-free product. The carbonate component is selected from among ammonium carbonate or bicarbonate, an alkali metal carbonate or bicarbonate, or an alkaline metal carbonate or bicarbonate while the sulfite component is an ammonium sulfite or bisulfite, alkali metal sulfite or bisulfite, or an alkaline metal sulfite or bisulfite.
