Patent ID: 7364669

Claim:
A method for reducing the reactivity of hydrated calcium hypochlorite comprising: a) selecting at least two different hydrated inorganic salts based on each of the hydrated inorganic salts having an enthalpy, ΔH, of at least 150 calories/gram, and having a phase transition temperature, as defined by the melting point of 19° C. to 200° C., b) thereafter adding to the hydrated calcium hypochlorite said at least two different hydrated inorganic salts to form a mixture with the hydrated calcium hypochlorite, c) whereby said mixture provides water release in an endothermic reaction to sufficiently quench dangerous reactions and reduce potential for a conflagration while providing increased chlorine stability as compared to hydrated calcium hypochlorite blends containing a single hydrated inorganic salt, wherein said mixture comprises at least 40% by weight hydrated calcium hypochlorite, and at least two of 0.1 to 19% by weight magnesium sulfate heptahydrate, 0.1 to 19% by weight potassium aluminum phosphate dodecahydrate, 0.1 to 19% by weight trisodium phosphate dodecahydrate, 0.1 to 10% by weight sodium tripolyphosphate hexahydrate and 0.1 to 19% by weight sodium tetraborate decahydrate.
