Product Description
Calcium Hypochlorite (Ca(ClO)₂) is a strong oxidizing agent widely used as a disinfectant and bleaching chemical. Supplied as white to pale yellow granular solid, it is highly soluble in water, releasing active chlorine for effective sanitation. It is used extensively in water disinfection, wastewater treatment, industrial sanitation, textile bleaching, and food processing sanitation across East Africa. Zenco Chemicals supplies Calcium Hypochlorite in Kenya, Uganda, Tanzania, Rwanda and the wider East African region, backed by technical support and reliable distribution. Proper PPE and storage in cool, dry, ventilated areas away from combustibles is essential due to its oxidizing nature.
