The product is a pure colorless transparent liquid. The relative density is 1.328 - 1.349, the melting point is 318.4 degrees Centigrade, and the boiling point is 1390 degrees Centigrades. Pure liquid caustic soda is called liquid caustic soda, which is a colorless and transparent liquid. The industrial product mostly contains impurities, mainly sodium chloride and sodium carbonate, and sometimes a small amount of iron oxide. When dissolved into a concentrated liquid caustic soda, most of the impurities will float to the surface and can be separated and removed.
Sodium hydroxide is a highly versatile substance and is a co-product of chlorine production. It is also known as caustic soda. It is represented as NaOH. It is one of the common alkalis or bases.
Uses of sodium hydroxide:
It is used in soap making.
It is used in the pharmaceutical industry in the manufacturing of various .
It is used in the paper industry to make paper.
It is used in the aluminum industry to manufacture aluminum products.
It is also used in detergents industry.

Sodium hydroxide is mainly used in paper making, cellulose pulp production, soap, synthetic detergent, synthetic fatty acid production and animal and plant oil refining. Textile printing and dyeing industry used as cotton desizing agent, refining agent and mercerizing agent. Chemical industry for the production of borax, formic acid, oxalic acid, phenol and so on. The petroleum industry is used to refine petroleum products and in oil field drilling mud. It is also used in the surface treatment of alumina, zinc and copper, as well as in glass, enamel, tanning, medicine, dyes and pesticides. Food grade products used in the food industry as acid neutralizer, can be used as citrus, peach peeling agent, can also be used as empty bottles, empty cans and other containers of detergent, as well as decolorizing agent, deodorant.
Sodium hydroxide used as a basic reagent, can be used as a neutralizer, with masking agent, precipitating agent, precipitating masking agent, a small amount of carbon dioxide and water absorbent, thin layer analysis of sterol color agent, etc., widely used in the manufacture of various sodium salt, soap, paper pulp, finishing cotton fabric, silk, viscose fiber, rubber products regeneration, metal cleaning, electroplating, bleaching.
In the cosmetics cream, sodium hydroxide and stearic acid saponification plays the role of emulsifier, used to make cream, shampoo and so on
