Novel compositions comprising calcium hypochlorite and a proportion of a polyacrylic acid compound have been produced. the compositions provide accurately controlled concentrations of available chlorine to bodies of water such as swimming pools by reducing the solubility off the calcium hypochlorite. In addition, when employing dispensers for water soluble chemicals in treating very hard or highly alkaline water, inhibition of scale formation and prevention of scale build-up in the dispenser is achieved when the novel compositions are used.

Method of inhibiting scale formation

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.
