Abstract
A calcium hypochlorite composition consists essentially of at least 75 percent by weight of Ca(OCl).sub.2, from about 6 to about 14 percent by weight of water, and less than 1.5 percent by weight of an alkali metal chloride. The novel composition provides increased amounts of sanitizing and disinfecting to, for example, water bodies while remaining safe with respect to thermal decomposition. Further, the composition reduces the rate of chlorine evolution during storage.
