Bleaching powder, with calcium hypochlorite Ca(ClO)₂ as its main active component along with calcium chloride and calcium hydroxide, appears as a white or grayish-white powder with a strong chlorine odor. This traditional highly effective, economical, and broad-spectrum chlorine-based disinfectant and oxidizing agent leverages strong oxidizing power, potent germicidal capabilities through available chlorine release, bleaching action, and stable storage properties for extensive use in drinking water disinfection, public health sanitation, textile bleaching, industrial wastewater treatment, and aquaculture disinfection.
Core Applications
Drinking and Domestic Water Disinfection
Bleaching powder serves as a crucial drinking water disinfectant in remote areas, small rural water systems, emergency relief, and field operations. Upon dissolving in water, it generates hypochlorous acid (HClO) that rapidly kills pathogenic microorganisms like bacteria and viruses, preventing waterborne diseases. It's also used for periodic cleaning and disinfection of domestic water tanks and reservoirs to control microbial growth.
Public Health and Environmental Disinfection
Prepared into specific concentration solutions for spraying or wiping disinfection in hospitals, schools, public spaces, garbage stations, toilets, and post-disaster environments. Effectively kills various pathogens and controls disease transmission, including emergency disinfection of patient excreta and contaminated areas during infectious disease outbreaks.
Textile and Paper Industries
Serves as an inexpensive bleaching agent for natural fibers like cotton and linen, removing natural pigments and impurities. Also used for pulp bleaching in small-scale paper mills and specific manufacturing processes.
Industry and Aquaculture
Controls algae and bacterial growth in industrial cooling water systems. Used for pond clearing in aquaculture and disinfection of livestock/poultry housing, feeding equipment, and transport vehicles to prevent animal diseases. Also utilizes strong oxidizing properties for treating cyanide-containing wastewater.
Product Characteristics
This product typically contains 25%-35% available chlorine (ordinary bleaching powder) or higher concentrations in high-test formulations. Disinfecting and bleaching efficacy depends directly on available chlorine content. The product is hygroscopic and decomposes easily in humid air or under light, requiring sealed storage protected from light and kept in cool, dry conditions.
Important Safety Warnings
Strictly prohibited from mixing with acids – contact with acids (like toilet cleaners) causes immediate reaction, rapidly releasing toxic chlorine gas (Cl₂) that can cause severe poisoning and be life-threatening
Corrosive and irritating – solutions irritate and corrode skin, eyes, and respiratory mucosa; wear protective gloves, goggles, and masks in well-ventilated areas
Damages fabrics and metals – high concentrations or prolonged soaking can damage cotton/linen fibers and corrode metals
