Segmentation Analysis

By Process

Sodium Process Dominated Market Owing to Its Efficiency and Cost-Effectiveness

On the basis of process, the market is segmented into sodium process and calcium process.

The sodium process held a dominant global calcium hypochlorite market share in 2024. The sodium process is more widely adopted and dominant due to its cost-effectiveness and efficiency compared to traditional methods. The sodium process utilizes sodium hydroxide and chlorine gas, making it a more commercially viable option, especially for large-scale water treatment applications. The sodium process is generally cheaper to operate, leading to lower production costs for manufacturers. It has also benefited from technological advancements in automated dosing systems and packaging technologies, which will maintain this production process dominance in the market.

The calcium process produces a dry, more stable form of calcium hypochlorite, making it easier to handle and store. This dry form is also less affected by moisture, which is crucial in regions with varying climates. The product produced from this process is widely used in industrial and municipal water treatment, swimming pool sanitization, and other applications where a stable and efficient disinfectant is needed. As a result, the calcium process will experience the fastest growth over the forecast period.  

By Form

Granular & Powder Segment Held a Dominant Share Due to Wide Adoption in Water Treatment & Industrial Applications

Based on form, the market is bifurcated into granular & powder and tablet.

The granular & powder segment accounted for a major market share in 2024 and will likely continue its dominance during the forecast period. Granular & powder form is preferred for disinfection and water treatment due to its ease of handling, stability, and cost-effectiveness compared to tablets. Granular forms are often more concentrated, requiring less material for the same disinfection dosage. Calcium hypochlorite is often supplied in lined drums for granules and in bags or buckets for powder, allowing for efficient storage and handling. In addition, the powdered and granular form offers a fast release of chlorine, offering rapid functionality to users and making it an ideal choice among water treatment and industrial applications.

The tablet segment is anticipated to have a significant growth rate due to its increasing use in specialty applications. Tablets are more convenient for dosing, require less storage space, and offer better shelf life. Swimming pool owners mostly prefer tablets due to their slow release and convenience. In addition, they are highly adapted for household or portable applications where ease of handling, safety, and portability are primary requirements.
