Calcium Hypochlorite is a high-purity oxidizing solid widely used as a disinfectant, bleaching agent, and sanitizer in laboratory, industrial, and water treatment applications, providing reliable chlorine release and strong antimicrobial activity.
🏭⚗️ Production
Manufactured under controlled industrial conditions to ensure consistent available chlorine content, low levels of impurities, and high chemical stability. Each batch is quality-checked for assay, moisture content, and particle uniformity. Packaged in airtight, moisture-resistant containers to prevent degradation, caking, and accidental release of chlorine gas during storage and transport.
🔬 Properties
A white to off-white granular or powdered solid with strong oxidizing properties. Highly soluble in water and releases chlorine upon dissolution. Chemically stable under dry storage conditions but reacts vigorously with moisture, acids, and organic materials. Store in a cool, dry place in tightly sealed containers away from heat, direct sunlight, and incompatible substances.
🧪 Applications
Used as a disinfectant for water treatment, laboratory surfaces, and equipment cleaning. Serves as a bleaching agent and strong oxidizing reagent in controlled laboratory and industrial processes. Provides consistent antimicrobial and oxidative performance in applications requiring chlorine release.
⚠️ Safety
Strong oxidizer and corrosive. Causes severe irritation to eyes, skin, and respiratory tract; inhalation of dust may be harmful. Reacts violently with organic materials, reducing agents, and acids. Handle with appropriate PPE, including gloves, eye protection, and lab coat, and work in well-ventilated areas. Store securely in tightly closed containers away from heat, moisture, and incompatible substances, and follow proper hazardous chemical disposal guidelines.
