According to the report by Expert Market Research (EMR), the global caustic soda market stood at a volume of around 83.99 MMT in 2024. Aided by the widespread industrial applications of caustic soda and the growing demand for chemicals in end-use sectors, the market is projected to grow at a CAGR of 2.30% between 2025 and 2034 to reach a volume of about 105.43 MMT by 2034.
Caustic soda, also known as sodium hydroxide (NaOH), is an essential industrial chemical with strong alkaline properties. It is widely used in manufacturing processes across multiple industries, including textiles, pulp and paper, soaps and detergents, water treatment, and chemicals. The product is also crucial in petroleum refining, alumina extraction, and pharmaceutical production.
The caustic soda market is witnessing consistent growth, supported by the expansion of industrial production and infrastructure development across emerging economies. Rapid industrialisation and urbanisation, especially in countries such as China, India, and Brazil, are driving the consumption of caustic soda in applications such as cleaning agents, textile processing, and chemical synthesis.
In the pulp and paper industry, caustic soda is used extensively in the chemical pulping process to separate lignin from cellulose fibres. It plays a vital role in paper bleaching and deinking recycled paper. The resurgence of the global packaging sector and rising demand for paper-based products are contributing to the increasing use of caustic soda in this industry.
Additionally, the use of caustic soda in water treatment is gaining prominence due to increasing environmental concerns and government regulations related to wastewater management. Caustic soda helps in neutralising acidic wastewater and facilitating the removal of heavy metals and impurities, thus improving the quality of discharged water.
