Granular calcium hypochlorite containing from about 0.001 to about 1.0 weight percent of finely-divided polyfluorinated polymer, e.g., polytetrafluoroethylene, dispersed throughout the granules is described. The product may be compressed and formed into shaped articles, e.g., tablets. The granules may be prepared by admixing the polyfluorinated polymer with particulate calcium hypochlorite, compacting the mixture and granulating the compacted product. Tablets prepared from the polyfluorinated polymer containing granular calcium hypochlorite dissolve in water at a rate slower than tablets prepared without the polyfluorinated polymer. Finely-divided calcium hypochlorite powder, e.g., powder of less than about 10 microns in size, is rendered more conveyable and compactible by the addition of the finely-divided polyfluorinated polymer; and mixtures of finely-divided calcium hypochlorite powder and particulate calcium hypochlorite is rendered more readily compactible.
