Calcium Hypochlorite Market Insights, By Manufacturing Process

Calcium Process contribute the highest share of the market owing to its growing use in emergency and portable water systems

Calcium Process contributes the highest market share of 68.8% in 2025. The Calcium Process involves reacting chlorine gas with a slaked lime (calcium hydroxide) suspension. This results in the precipitation of calcium hypochlorite. As slaked lime is much cheaper than sodium hydroxide, the raw material costs for the Calcium Process are significantly lower. For instance, SDS, a specialist in water reuse technology, has introduced its grey water treatment system to simplify and reduce the cost of grey water recycling for developments like smaller hotels, residential complexes, and commercial buildings, enabling them to operate low-maintenance systems more efficiently.

Calcium Hypochlorite Market Insights, By Form

Powder contributes the highest share of the market owing to its demand in emergency and military use

Powder contributes the highest market share of 48.8% in 2025. Calcium hypochlorite in powder form can be easily dissolved in water to produce chlorine-based solutions for disinfection and water treatment. Its high surface area allows for rapid dissolution which is important in applications like municipal water treatment where quick dissociation is needed.

Calcium Hypochlorite Market Insights, By Applications

Agrochemicals contribute the highest share of the market owing to its seed & equipment disinfection

Agrochemicals contribute the highest market share of 41.9% in 2025. It is widely utilized as a fumigant, fungicide and general disinfectant in agricultural operations. Calcium hypochlorite solutions are effective at killing a broad spectrum of fungi, bacteria, viruses and molds that can destroy crops. In addition, various key companies are introducing agrochemicals. In June 2025, Arqivo, the newest player in India’s agrochemical industry and a subsidiary of Tagros Chemicals, made its official debut with a spectacular launch event held at Tarangi Resort in Jim Corbett, Uttarakhand. This is further anticipated to propel the calcium hypochlorite market demand.
