Calcium Hypochlorite 70% (HTH / Cal Hypo) is a high-potency dry chlorine donor containing 70.0% minimum available chlorine. Produced via the advanced sodium process, it dissolves rapidly to liberate active hypochlorous acid (HOCl) that destroys pathogenic bacteria, viruses, algae, and protozoa in drinking water and swimming pools.
Technical Description
White granular solid with a strong chlorine odor. Sodium-process formulation yields lower insoluble residue (<2.5%) and higher chemical stability than traditional bleaching powder.
