Calcium hypochlorite compositions that are classified as a Packing Group III Division 5.1 oxidizer material or as a non-Division 5.1 oxidizer material are described. In one embodiment, the compositions comprise an admixture of particulate calcium hypochlorite and particulate metaboric acid. The calcium hypochlorite is present in the composition in an amount and is of a concentration such that the composition would be classified as a Packing Group II Division 5.1 oxidizer in the absence of said particulate metaboric acid. Other embodiments described are solid shaped articles, e.g., tablets, comprising the described calcium hypochlorite-metaboric acid composition.

Calcium hypochlorite composition

Describes an aqueous composition of sodium potassium sulfide and methods for preparing this inter-alkali metal sulfide. One method described is the addition of sodium hydrosulfide to potassium hydroxide in an aqueous reaction medium. The aqueous sodium potassium sulfide composition preferably contains a slight excess of alkali metal hydrosulfide, e.g., sodium hydrosulfide. The sodium potassium sulfide is useful as a depilatory for removing hair from the hides of animals consumed as food.
