Overview,
Calcium Hypochlorite (Ca(OCl)₂) is a white to pale grey granular or tablet compound that releases chlorine when dissolved in water. It is one of the most effective and economical disinfectants for drinking water, wastewater treatment, swimming pools, and food processing facilities. Moon Bright Resources supplies premium-grade Calcium Hypochlorite with 65-70% available chlorine, manufactured under strict quality controls to ensure consistent dissolution rate, minimal residue, and long shelf life. Our product is trusted by municipal water authorities, hotel operators, and industrial laundries worldwide.

FAQ – Frequently Asked Questions
Q1: What is the difference between Calcium Hypochlorite and liquid chlorine (sodium hypochlorite)?
A1: Calcium Hypochlorite contains 65-70% available chlorine in a dry, stable form with a shelf life of 1-2 years. Liquid chlorine (sodium hypochlorite) typically contains 10-15% available chlorine and degrades within 3-6 months. Calcium Hypochlorite is more cost-effective for long-term storage, easier to transport, and produces less sludge. However, it requires pre-dissolving before application and may increase calcium hardness in pool water.
Q2: How should Calcium Hypochlorite be stored safely?
A2: Store in a cool, dry, well-ventilated area away from direct sunlight, heat sources, and moisture. Keep containers tightly sealed. Store away from acids, ammonia, organic materials, and combustible substances — contact can cause fire or toxic gas release. Do not store on wooden pallets or concrete floors prone to moisture. Use only original containers with proper labels. Shelf life is 12-24 months under ideal conditions.
Q3: Do you offer OEM / private label packaging?
A3: Yes, Moon Bright Resources provides full OEM services for Calcium Hypochlorite. We can package under your brand name with custom-printed containers (1 kg to 45 kg), custom tablet sizes (200g standard or custom weight), and your choice of granular mesh size. Minimum OEM order quantity is 5 metric tons. We also offer private label with shrink wrap, custom inserts, and safety labeling in multiple languages.
Q4: What is your minimum order quantity (MOQ)?
A4: MOQ is 1 kg (one container) for sample orders, 100 kg for small commercial orders, and 5 metric tons for wholesale pricing. Bulk orders of 10 metric tons or more qualify for discounted rates. For OEM private label orders, MOQ is 5 metric tons. Contact our team for container load pricing (typically 20 metric tons per 20ft container).
Q5: Is Calcium Hypochlorite safe for drinking water disinfection?
A5: Yes, when used correctly, Calcium Hypochlorite is approved by the WHO and EPA for emergency drinking water disinfection. Typical dosage is 1-2 grams per 1000 liters to achieve 1-2 ppm free chlorine residual. Always pre-dissolve in water before adding. Our product meets NSF/ANSI 60 standards for drinking water treatment. We provide detailed dosing instructions with each order.
