Market Overview:

The global caustic soda market size reached 80.6 Million Tons in 2022. Looking forward, IMARC Group expects the market to reach 89.7 Million Tons by 2028, exhibiting a growth rate (CAGR) of 1.7% during 2023-2028.

Caustic soda, also known as sodium hydroxide (NaOH), is a white-colored solid ionic compound comprising hydroxide anions OH- and sodium cations Na+. It is strongly alkaline and chemically obtained by electrolyzing sodium chloride (NaCl). It is highly soluble in water, moderately soluble in alcohol, and insoluble in ether and non-polar solvents. It is used in formulating various chemical products due to its corrosive and reactive nature. Besides this, NaOH is used in preparing soda lime, cleaning and disinfectant products, and in the extraction of aluminum by purifying bauxite. As a result, it finds extensive applications in various industries like textiles, paper, chemical, and automotive.

Caustic Soda Market Trends:

Rapid industrialization and the expansion of the chemical industry represent the key factors positively influencing the market. In addition, the increasing consumption and scarcity of freshwater and strict regulations to control contamination in seas, lakes, ponds, rivers, and oceans are strengthening the market growth. This can also be accredited to the growing utilization of caustic soda as a water treatment chemical that helps increase the pH level of water by absorbing carbon dioxide (CO₂) and water. Apart from this, the rising utilization of aluminum across various industries, such as automotive, construction, and packaging, is catalyzing the demand for NaOH worldwide. Furthermore, the introduction of advanced technologies in the manufacturing processes of NaOH, along with extensive investments in research and development (R&D) activities, is expected to propel the market growth.
