The global caustic soda market size was valued at 83.2 Million Tons in 2024. Looking forward, IMARC Group estimates the market to reach 95.7 Million Tons by 2033, exhibiting a CAGR of 1.41% during 2025-2033. Asia-Pacific currently dominates the market. The increasing demand for lightweight materials such as aluminium, rapid expansion in the pulp and paper industry, and the significant growth of water treatment services globally represent some of the key factors driving the market.
Caustic soda, also known as sodium hydroxide, is a highly corrosive, strong alkali. It is a white, solid, ionic compound at room temperature and when it is dissolved in water or neutralized with acid, it liberates substantial heat. It is highly soluble in water, ethanol, and methanol and forms a highly alkaline solution. It helps break down fats, oils, and other organic compounds, which makes it an effective cleaner. It finds extensive application in water treatment plants as it aids in neutralizing pH levels and assisting in the removal of impurities. Moreover, it is used as a base in many chemical reactions because it facilitates reactions by accepting protons.
The expansion of the global textile industry is increasing the utilization of caustic soda for fabric processing and dyeing. Additionally, the growing adoption of caustic soda in the burgeoning chemical industry is positively influencing the market. Caustic soda is a fundamental reactant in many chemical manufacturing processes. It is used in the synthesis of several organic and inorganic compounds, such as solvents, plastics, and fabric.
