Key Properties & Specifications

Major Industrial Applications & Uses

Bleaching Powder is a versatile chemical workhorse, essential for ensuring safety and quality in many critical industries.

Water Treatment and Sanitation

The primary and most vital use of bleaching powder is as a disinfectant for drinking water. It effectively kills a broad spectrum of harmful microorganisms, including bacteria, viruses, and protozoa, making water safe for human consumption. It is also widely used for:

• Sanitizing municipal water supplies and wastewater treatment plants.
• Disinfecting swimming pools to control algae and pathogen growth.
• General sanitation in public spaces, hospitals, and drains to prevent the spread of disease.

Textile Industry

In the textile industry, bleaching powder is a cornerstone for processing natural fibers. It is used to bleach cotton and linen, removing natural pigments and impurities to produce a clean, white base fabric. This crucial pre-treatment step ensures uniform dyeing and printing for a high-quality final product.

Pulp and Paper Industry

Bleaching powder is a key agent used to whiten wood pulp, which is the primary raw material for paper. It effectively removes lignin and other organic colorants, resulting in bright, high-quality white paper products.

Chemical Manufacturing

As a strong oxidizing agent, bleaching powder is used in many chemical industries as a reactant or catalyst. It is notably used in the commercial production of chloroform.

Household & Institutional Cleaning

Its powerful germicidal properties make bleaching powder a common ingredient in household and industrial cleaning products. It is highly effective for:

• Disinfecting floors, bathrooms, toilets, and other high-touch surfaces.
• Removing tough stains and mildew from clothing and surfaces.

Agriculture and Food Processing

Bleaching powder is utilized to disinfect tools, equipment, and irrigation water in agriculture to prevent the spread of plant diseases. In the food and beverage industry, it is used to sanitize production surfaces, ensuring a hygienic environment.

Advantages of Bleaching Powder

• Cost-Effective Disinfection: Provides a powerful sanitizing solution at an economical price point.
• Stable and Easy to Store: As a solid powder, it is more stable and easier to transport and store than liquid chlorine.
• Broad-Spectrum Efficacy: Kills a wide range of bacteria, viruses, fungi, and other pathogens.
• Proven Performance: A trusted and reliable chemical used for over a century in public health and industry.

Safety & Handling

Bleaching powder is a strong oxidizing agent and is corrosive. Always handle with appropriate PPE, including gloves, eye protection, and respiratory protection.

Store in a cool, dry, well-ventilated area away from acids, organic materials, and moisture. Contact with these substances can cause a dangerous release of chlorine gas.

Always refer to the Safety Data Sheet (SDS) for complete handling, storage, and disposal guidelines.
