CALCIUM HYPOCHLORITE (CHLORINATED LIME) CHLORIDE OF LIME (HTH)

• CALCIUM HYPOCHLORITE, (CHLORINATED LIME) CHLORIDE OF LIME(HTH) – (PubChem) – Calcium hypochlorite appears as a white granular solid (or tablets compressed from the granules) with an odor of chlorine. Toxic, irritating to the skin. Noncombustible, but will accelerate the burning of combustible materials. Prolonged exposure to fire or heat may result in the vigorous decomposition of the material and rupture of the container. Diluted samples may undergo reactions as described above if they contain less than 39% available chlorine but take longer to become involved and react less vigorously. Used for water purification, disinfectant for swimming pools, for bleaching paper and textiles. – Source: CAMEO Chemicals
