Sodium Hydroxide Caustic Soda Flakes Alkali 99% NaOH CAS 1310-73-2
Sodium Hydroxide, also called caustic soda, is a white solid inorganic compound with the chemical formula NaOH. It is a strong base with a molar mass of 40.00 g/mol, and it is highly soluble in water but insoluble in other solvents. It has a refractive index of 1.4. It is available in three forms, including sodium hydroxide pearls, sodium hydroxide pellets, and sodium hydroxide granules.
Basic Information
| Property: | Strong alkali |
| HS Code: | 2815110000 |
| Molecular weight: | 40.01 |
| Property: | Caustic soda (NaOH), also known as sodium hydroxide is a strong, clear to hazy, liquid base. It is produced (along with chlorine and hydrogen) via the diaphragm or newer membrane electrolytic process, yielding a high purity caustic soda solution. |
| Specification: | Industrial Grade according to GB/T209-2006 |
| Storage: | 1.Stored in ventilated and dry warehouse or shed and the container must be sealed 2.Avoiding mixing and transporting with combustibles and acids 3.Avoiding rain and moisture during transportation 4.Don not use glass cork but rubber plugs when stored in glass bottles, or it is difficult to open after the reaction between caustic soda and silicon dioxide. |

3.Food grade products are used in the food industry as acid neutralizers and peelers for citrus, peach, etc.
When sodium hydroxide is used as a basic reagent, it can be used as a neutralizing agent, a masking agent, a precipitating agent, a precipitation masking agent, a small amount of carbon dioxide and water absorbent, a color developer for the determination of ketosterol by thin layer analysis, etc. It is widely used. It is used in the manufacture of various sodium salts, soaps, pulp, finishing cotton fabrics, silk, viscose fibers, regeneration of rubber products, metal cleaning, electroplating, bleaching, etc.
In cosmetic creams, the saponification of sodium hydroxide and stearic acid acts as an emulsifier, which is used to make vanishing cream, shampoo and so on.
