What is Calcium Hypochlorite?
Calcium Hypochlorite, CAS 7778-54-3, is a white granular solid or tablet with a characteristic chlorine odour. It is a strong oxidising agent and an effective source of available chlorine.
Calcium Hypochlorite 70% is widely used for water disinfection, bleaching, sanitation and algae control. It reacts with water to release hypochlorous acid, which provides the disinfecting action. The product must be stored and handled carefully because it can intensify fire and may react dangerously with acids, organic materials and reducing agents
