Calcium hypochlorite tablet

Abstract

Novel solid articles comprising a compressed mixture of granular calcium hypochlorite and from about 0.5 to about 5.0 weight percent, basis the calcium hypochlorite, of solid wax binder selected from the group consisting of microcrystalline hydrocarbon wax and alkali metal salts of oxidized microcrystaline hydrocarbon wax are described. The novel solid articles are provided in the shape of, for example, tablets, which are prepared by dry blending the granular calcium hypochlorite and wax binder and feeding the mixture to a tableting press. The articles dissolve at a controlled rate, depending on the amount of binder used, in water, thereby providing a source of available chlorine over an extended period of time.
