Caustic soda, also known as sodium hydroxide (NaOH), is a highly versatile and widely used inorganic chemical compound. It is a strong alkali used in various industries such as pulp & paper, textiles, chemicals, soaps & detergents, water treatment, and aluminum production.
It is typically produced through the chlor-alkali process, which also yields chlorine and hydrogen as byproducts. Given its critical role in both industrial and consumer applications, the caustic soda market is closely linked to global economic trends and industrial output.
The global caustic soda market is expected to grow from USD 50.69 billion in 2023 to USD 70.14 billion by 2033, at a CAGR of 3.30% during the forecast period 2024-2033.
