Abstract
Describes a composition comprising a mixture of (1) a major amount of calcium hypochlorite, e.g., hydrated calcium hypochlorite, and (2) a minor amount of calcium hypochlorite-compatible hydrophobic additive (other than discrete particulate Group IIA or IIIA metal stearates) in amounts sufficient to provide the composition with reduced hydrophilic properties. The composition has a solution rate in water at standard conditions that is less than the calcium hypochlorite used to prepare the composition, but sufficient for the intended application. Describes also calcium hypochlorite compositions in which the hydrophobic additive is an organo-silicon material, or a metal oxide, e.g., amorphous precipitated silica, treated with a hydrophobizing agent, such as an organo-silicon material, e.g., an organo-silane and/or organo-siloxane material.
