Caustic Soda Flake: An Essential Chemical with Multiple Uses

What are caustic soda flakes? In this article, learn everything including the properties, characteristics, uses of this chemical and get to know the market of buying and selling Caustic Soda flakes.

An introduction to the alkaline composition caustic soda flakes (solid sodium hydroxide)

Caustic Soda flakes or solid pieces of caustic soda (sodium hydroxide) is a common and well-known alkaline compound. This solid substance is also sold in the market under the common name of

sodium hydroxide or caustic soda.

Solid sodium hydroxide (NaOH) is in fact a solid mass in a shell or flakes state. This combination is matte white or milky.

Caustic soda flakes is soluble in water and alcohol and is highly absorbent. This substance is classified in the group of corrosive chemicals. flakes sodium hydroxide is obtained by evaporation of liquid caustic soda.

If you come across the following common names in the caustic soda flakes market, it means the same alkaline substance:
solid sodium hydroxide; sodium hydroxide; caustic soda; Caustic soda NaOH, solid NaOH; caustic soda NaOH; Sodium hydroxide (Natrium hydroxide); sodium hydrate; caustic soda; caustic soda 98%

Solid caustic soda is used in the processes of synthesis of organic compounds, refining of petroleum products, textile industries in silk production, and fabric bleaching, in paper making, soap making, aluminum metal production, sodium preparation, glass making industries, etc.

A brief look at the history of caustic soda flakes

Sodium hydroxide (caustic soda flakes) was first prepared by soap makers. This method was implemented based on the soap preparation instructions published in a book in Arabic.

This book was compiled by the king of Yemen named “Muzaffar Yusuf ibn Umar ibn Ali ibn Rasool”. This method is considered as one of the industrial inventions of that period.
In this method, it was said that water should be passed through the alkaline solution; Therefore, the final product will be sodium hydroxide compound. Alkaline composition in this method, impure sodium carbonate and quicklime or calcium oxide were selected.

It is interesting that most of the soap making industries in European countries based the product preparation method on these innovations and followed it.

In 1791, French chemist and surgeon Nicolas LeBlanc (1742-1806) invented a process for the mass production of sodium carbonate, natural “soda ash” (= impure sodium carbonate obtained from the ashes of sodium-rich plants).

This new method replaced the previous unconventional method. However, in the 20th century, the main method of producing solid sodium hydroxide or caustic soda flakes is the electrolysis of sodium chloride. We will talk about this in the next section.

Uses of caustic soda flakes

  1. Soap and Detergent Industry: Caustic soda is an essential ingredient in the production of soap and detergents. It is used to neutralize the fatty acids present in oils and fats to form soap.
  2. Pulp and Paper Industry: Caustic soda is used in the manufacture of paper and pulp as a bleaching agent. It helps to brighten the paper and remove impurities.
  3. Water Treatment: Caustic soda is used in water treatment plants to adjust the pH levels of water. It helps to remove impurities and pollutants, making the water safe for consumption.
  4. Textile Industry: Caustic soda is used in the production of textiles to remove impurities and improve the quality of the fabric. It is also used as a degreasing agent.
  5. Chemical Industry: Caustic soda is used as a raw material in the production of other chemicals, such as chlorine and sodium metal.
  6. Drilling Fluid: Caustic soda is used in oil and gas drilling operations to maintain the pH levels of drilling fluids. This helps to prevent corrosion of the drilling equipment.
  7. Cleaning and Degreasing: Caustic soda is used as a cleaning agent for various surfaces, such as ovens, drains, and metal surfaces. It is also used as a degreaser for removing grease and oil from metal parts.


In conclusion, caustic soda flakes play an important role in various industries, such as soap and detergent, pulp and paper, water treatment, textile, chemical, drilling fluid, and cleaning and degreasing. Its versatility and effectiveness make it an essential chemical for many processes. However, it is important to handle caustic soda with care, as it is a strong alkali and can cause chemical burns. Proper protective equipment and caution should be exercised when using caustic soda.
