Abstract
Calcium hypochlorite compositions, suitable for bleaching and sanitation uses, are provided which have improved resistence to exothermic decomposition. These novel compositions are granules comprised of a core of calcium hypochlorite encapsulated with a coating comprised of a mixture of calcium hypochlorite dihydrate and a water soluble inorganic salt which is non-reactive with and stable in contact with calcium hypochlorite. Generally the coating comprises from about 5 to about 60 percent by weight of each granule and the proportion of water soluble salt ranges from about 0.1 to about 15 percent by weight of each granule. The granular product also resists dusting and caking and has improved retention of its available chlorine on storage.
