Abstract
Novel compositions comprising calcium hypochlorite and a hydrazide of a monocarboxylic acid containing from about 10 to about 24 carbon atoms have been produced. The compositions provide accurately controlled concentrations of available chlorine to bodies of water such as swimming pools by reducing the solubility of the calcium hypochlorite.
