Calcium Hypochlorite (Chlorine)

Whatsapp Order

Calcium Hypochlorite (Ca(ClO)₂) is a white to slightly yellow crystalline powder or granules known for its strong oxidizing and disinfectant properties. The 65% grade indicates the available chlorine content, making it a powerful bleaching, sanitizing, and oxidizing agent. It is commonly used for water treatment, sanitation, and as a bleaching agent in industrial and household applications. Calcium Hypochlorite dissolves in water to release hypochlorous acid, which effectively kills bacteria, viruses, and fungi.
