By Application Insights

The organic chemicals segment is estimated to witness significant growth during the forecast period.

The market is primarily driven by its extensive applications in various industries, particularly in the production of organic chemicals. In 2024, the organic chemicals segment led the market, with caustic soda being a crucial reactant in the manufacturing of organic acids, organic resins, and chemicals such as epoxy resins, propylene oxide, polycarbonates, ethylene amines, pigments, and dyes. Caustic soda is employed in the base-driven hydrolysis process of esters, alkyl halides, and amides. However, potassium hydroxide serves as a substitute due to its higher solubility in several organic solvents. It plays an essential role in the production of valuable organic chemicals, including titanium dioxide, aluminum, hydroxide anion, and chlorine derivatives.

It is also used in water treatment, soaps and detergents, pulp and paper, and pharmaceuticals. Despite environmental concerns, the demand continues to grow, driven by the transport sector, soap and detergent industry, and the need for water treatment and descaling agents. Impurities and pollutants in caustic soda can be mitigated through advanced technologies, ensuring sustainability in its production and use.
