<p>A solid calcium hypochlorite composition that is not classified as a Division 5.1 oxidizer material is described. The composition comprises an admixture of particulate (a) calcium hypochlorite, (b) hydrated borate salt, e.g., disodium tetraborate decahydrate, and (c) aluminum salt, e.g., hydrated aluminum sulfate and/or anhydrous aluminum sulfate. The calcium hypochlorite is present in the composition in an amount sufficient to provide a free available chlorine content that would result in the composition being classified as a Division 5.1 oxidizer in the absence of (b) and (c). The aluminum salt is present in the composition in at least a flocculating amount, and the hydrated borate salt is present in an amount at least sufficient to neutralize 100 % of the aluminum salt. Also described are solid shaped articles, e.g., tablets, comprising the calcium hypochlorite composition of the present invention.</p> |
