Sodium hydroxide, commonly known as caustic soda, is an inorganic compound with a chemical formula of NaOH. It is a white crystal at room temperature, generally in the form of flakes or particles. It is easily soluble in water and forms an alkaline solution, which is highly corrosive. It has deliquescence, and it is easy to absorb water vapor (deliquescence) and carbon dioxide (deterioration) in the air, and hydrochloric acid can be added to check whether it is deteriorating.
Caustic soda has many applications in different fields, it is suitable for water treatment and softening, oil field drilling mud, petroleum product refining, sanitation, hygiene products. It can also be used as a raw material for the production of soaps, detergents, textiles and paper. In addition, it is also used as a pigment for acidity regulators, alkalis, impregnating agents.

The Main Applications of Caustic Soda
- Industrial grade caustic soda can be widely used in papermaking, rayon, textile printing and dyeing, soap making, medicine, dyestuff, chemical industry, metallurgy, petroleum refining and other industries. It is also the main raw material for pesticides, tanning, organic synthesis, and electroplating industries.
- Food grade caustic soda can be used as acid neutralizer in food industry, peeling agent for citrus, peaches, etc., as well as detergent for empty bottles and cans, as well as decolorizer and deodorizer.
In sewage treatment plants,
caustic soda can reduce the hardness of water through a neutralization reaction. In the industrial field, it is a regenerant for ion exchange resin regeneration. Sodium hydroxide is strongly alkaline and relatively soluble in water. Since sodium hydroxide has a relatively high solubility in water, it is easy to measure the dosage and can be conveniently used in various fields of water treatment.
