The global Flake Caustic Soda market size is predicted to grow from US$ 4479 million in 2025 to US$ 5098 million in 2031; it is expected to grow at a CAGR of 2.2% from 2025 to 2031.

Flake caustic soda, also known as sodium hydroxide in flake form, is a highly corrosive, white, solid alkali. It is widely used in various industries such as chemical manufacturing, paper production, water treatment, and soap making. The flakes are produced by evaporating liquid caustic soda, resulting in a concentrated and easy-to-handle solid form. Due to its strong alkaline nature, it is effective in neutralizing acids, breaking down organic materials, and regulating pH levels. However, it requires careful handling as it can cause severe burns and reacts violently with water and acids.

The flake caustic soda industry is experiencing steady growth, driven by increasing demand from key sectors such as chemical manufacturing, water treatment, and the pulp and paper industry. The global push for cleaner water and stricter environmental regulations has boosted its use in wastewater treatment and pH regulation. Additionally, the rising demand for alumina in the aluminum industry and the expansion of the textile sector are further propelling market growth. However, the industry faces challenges such as fluctuating raw material costs and the need for safer handling practices due to its hazardous nature. Innovations in production technology and a focus on sustainable practices are expected to shape the future of this market, with Asia-Pacific emerging as a major consumer due to rapid industrialization.
