The calcium hypochlorite market size was valued at US$ 615.14 million in 2024 and is expected to reach US$ 874.89 million by 2031; it is estimated to register a CAGR of 5.4% from 2025 to 2031.

Calcium hypochlorite is highly used in various industrial settings. It is also one of the raw materials used in cleaning products at home. It is used in detergents, soaps, grease or stain removers, cleaners for drugs, and other medical devices. Calcium hypochlorite is also highly used in household equipment sanitation. With rapid urbanization and modernization, there is a rising emphasis on maintaining clean and sanitized living environments. This increasing awareness about hygiene and cleanliness is particularly evident in urban areas where population density and shared living spaces amplify the risk of spreading germs and pathogens. As a result, consumers increasingly prioritize effective cleaning practices, including the regular use of detergents, to safeguard themselves and their families against illness and infection. Moreover, the COVID-19 pandemic raised awareness of hygiene and cleanliness across the world. The pandemic emphasized the importance of proper sanitation and hygiene practices in residential, commercial, and industrial places. Food processing, hospitality, and manufacturing sectors require effective sanitization. The growing concern about enabling a healthier and hygienic environment is leading to the increasing demand for detergents and cleaners from the industrial sector, thereby driving the calcium hypochlorite market.

In terms of application, the market is categorized into water treatment, house cleaners and detergents, agrochemicals, pulp and paper, food and beverage, and others. The water treatment segment held a larger market share in 2024 and is expected to register the highest CAGR from 2025 to 2031. Water and wastewater treatment is a major application sector for calcium hypochlorite. Calcium hypochlorite is easier and safer to use than other chlorine sources for water treatment. Calcium hypochlorite is used to disinfect swimming pool water, drinking water, and industrial water. It effectively kills parasites, bacteria, viruses, and other microorganisms in the water, thus ensuring the safety of the water and its quality. Calcium hypochlorite aids in oxidizing organic matter and odor substances in water, which helps remove pollutants in water and improve the taste and quality of water. In addition, calcium hypochlorite is also used as a bleaching agent, which is effective in removing impurities and colors when treating water sources that contain colors or stains.

Calcium hypochlorite offers several advantages for water treatment compared to other disinfection methods, such as ozone. To create a solution, solid calcium hypochlorite is dissolved in water. In contrast, ozone must be generated using a specialized ozone generator.

Asia Pacific is estimated to register the fastest CAGR in the global calcium hypochlorite market from 2025 to 2031. The calcium hypochlorite market in Asia Pacific witnessed significant growth due to the growing textile production in the region. According to the Asian Development Bank, as the population in the Asia Pacific is increasingly shifting to urban areas-2.5 billion or 55% of the population is predicted to live in urban areas by 2030-water demand is projected to increase by nearly 55%. According to the World Trade Statistical Review 2022, China and Vietnam are among the world's largest textile exporters.
