South Korea Caustic Soda Market Report and Forecast 2025-2034

South Korea Caustic Soda Market Outlook

The South Korea caustic soda market size is projected to grow at a CAGR of 3.30% between 2025 and 2034.The major drivers of the market include presence of strict environmental regulations, growth of the aluminium manufacturing industries in South Korea, and increasing demand for wastewater treatment.

Key Trends in the Market

Caustic soda, also known as lye, is a chemical compound that is corrosive in nature and is used for various applications such as manufacturing of soap or cleaning drains. The chemical name of this inorganic compound is sodium hydroxide and it is highly soluble in water and absorbs carbon dioxide and moisture from air.

• Various innovations such as increased emphasis on handling and delivery of caustic soda, recycling and reuse of caustic soda, and replacement of mercury cells with environmentally friendly technologies such as diaphragm and membrane cells is boosting the South Korea caustic soda market demand.

• The demand for caustic soda in South Korea from end use industries is rising. This increase can be attributed to the growing applications of caustic soda in various petrochemical processes, including the production of vinyl chloride and ethylene dichloride monomers. The demand for caustic soda is also increasing from the textile industry as it aids in the mercerisation of rayon and cotton.

• Integration of digital technologies such as data analytics and advanced monitoring systems in the caustic soda production plants has helped improve the manufacturing process control and efficiency. These advancements enable real time optimisation which result in enhanced streamlined operations.
