Caustic soda is a white semi transparent solid in the form of flakes. It is a basic chemical raw material and is widely used in light textile industries such as papermaking, synthetic washing, soap, viscose fibers, artificial silk, and cotton fabrics. It is also used in pesticide, dye, rubber, and chemical industries, petroleum drilling, refining petroleum oils and tar, as well as in national defense industry, machinery industry, wood processing, metallurgy industry, pharmaceutical industry, and urban construction. It is also used in the manufacturing of chemicals, paper, soap and detergent, artificial silk and glass paper, processing alumina to produce alumina, and is also used in the mercerization of textiles, water treatment, and so on.

Chemical Properties |
Caustic Soda, a highly potent alkali with immense corrosiveness, primarily comes in the guise of flakes or blocks. Its solubility in water is remarkable, releasing heat as it dissolves, transforming into an alkaline solution. This alkaline nature also renders it susceptible to absorbing moisture and carbon dioxide from the atmosphere, causing it to deliquesce and deteriorate. Its unique properties make it a vital ingredient in various industrial processes, yet its handling requires utmost caution due to its corrosive nature..
