Sodium hydroxid,with the chemical formula NaOH, is commonly known as Caustic Soda. It is a strong alkali with strong corrosivity, generally in the form of flakes,pearls or lumps.Industrial grade Caustic Soda contains a small amount of sodium chloride and sodium carbonate, and is white translucent crystal.Its aqueous solution has an astringent and creamy feel.Sodium hydroxide is prone to deliquescent in the air, so solid sodium hydroxide is often used as a desiccant.It is very soluble in water and emits a lot of heat when dissolved. It`s also soluble in ethanol and glycerin.
Sodium hydroxide (NaOH) is extremely versatile. Used in the production of paper, soap, dyes, rayon, metal smelting, petroleum refining, cotton fabric finishing, coal tar product purification, and food processing, wood processing and machinery industries.
The product is a strongly alkaline substance which belong to 8 grade dangerous goods. with strongly irritating and corrosive, dust or smoke can irritate the eyes and respiratory tract, corrode the nasal septum, direct contact between the skin and eyes and NaOH can cause burns, and misuse can cause digestive tract burns, mucosal erosion, bleeding and shock.So it`s highly corrosive and requires the "corrosive item" mark.
