Product Description

General description:

Caustic Soda Formula: NaOH

Caustic soda or Caustic Soda Prill or Caustic Soda Flakes is also known as sodium hydroxide(NaOH) and Lye. This name is given because of the corrosive nature of the salt on plant tissues and animals. It is a versatile alkali. It is an extremely alkali and caustic base that deteriorates proteins at ordinary ambient temperatures and also causes serious chemical burns. Sodium hydroxide is a white solid ionic compound comprise of hydroxide anions OH- and sodium cations Na+.

Application & Usage:

In the Paper Industry, caustic soda is normally in the form of lye to separate the lignin that ties the fibers in the chemical pulping process. It is also used for paper recycling operations.
In the refining of edible oil, sodium hydroxide is utilized as a neutralizer to remove free fatty acids that can give the oil an annoying taste.
In the Petroleum Processing refineries, caustic soda is used for an alkalinity source in the liquid scrubbing of Sulphur dioxide in flue gases manufacture from crude-oil-fired steam generators used in thermally enhanced oil recovery. It allows the SO2 scrubber to run at a lower pH with a higher SO2 removal proportion. This process is called desulfurization.
In the mining and refining, the alumina is manufactured from bauxite, it is an ore that is extracted from topsoil in different tropical and subtropical regions using The Bayer he Bayer. To extract alumina, bauxite is crushed, washed, and dried. After that, it will be dissolved with sodium hydroxide at very high temperatures. Alumina is extracted in the form of sodium aluminate. To produce aluminum it required multiple processes to get that.
In the water treatment process, Caustic soda is very helpful in the pH neutralizing and adjustment of water streams. It is also used to raise the pH of water supplies.
In different industries, sodium hydroxide is often used as a cleaning agent. Especially for sterilization and cleaning of bottles in the beverage industry.
In chemical processing, caustic soda(NaOH) is used for delivering sodium to its final form and reactive agent in the production process and for many various purposes. It is also used to produce silicates and meta-silicates, bleach, fibers, also in food processing.

Industrial Utility and Chemical Profile

Renowned for its versatility, caustic soda in flake form is a mainstay in industries such as paper, chemicals, textiles, soaps, and detergents. It serves as an essential raw material or cleaning agent, exhibiting powerful alkaline and moisture-absorbing properties while remaining odorless and highly reactive.

Handling, Storage, and Safety Guidelines

Due to its corrosive nature (Dangerous Goods Class 8), handling caustic soda requires strict safety protocols such as using PPE and airtight containers. Store it away from moisture and acids in designated chemical areas to prevent hazardous reactions or degradation, ensuring maximum shelf life and operator safety.

Supply Flexibility and Compliance

Available in 25 kg HDPE bags with the option for custom packaging, caustic soda meets global regulatory codes (CAS No: 1310-73-2, HS Code: 28151110, UN 1823). Exported from India, supply quantities and packaging can be tailored according to customer requirements, supporting both large-scale and small-batch industrial needs.

FAQs of Caustic Soda:

Q: How should caustic soda be safely stored and handled?

A: Caustic soda must be stored in airtight containers away from moisture and acids. When handling, wear appropriate personal protective equipment (PPE), as it is highly corrosive and can cause severe burns on contact with skin or eyes. Always follow local safety guidelines for corrosive substances.

Q: What are the main industrial applications of caustic soda flakes?

A: Caustic soda flakes are widely used in the manufacture of chemicals, soaps, detergents, textiles, water treatment, paper, and petroleum products due to their strong alkaline properties. They also serve as cleaning agents in various industries.

Q: When should caustic soda be ordered to ensure optimal shelf life?

A: To maximize its 24-month shelf life, order caustic soda as per your usage requirements and ensure you have suitable storage conditions ready prior to delivery. Plan procurement based on turnover rates and storage capacities to prevent product degradation from exposure to moisture or contaminants.

Q: Where is your caustic soda manufactured and supplied from?

A: Our caustic soda is manufactured and exported from India, adhering to international standards. We cater to customers globally, fulfilling supply requirements as per specifications and destinations.

Q: What is the standard packaging for caustic soda shipments?

A: The standard packaging is 25 kg HDPE bags with an inner liner to provide moisture resistance, but packaging can also be customized as per specific customer requirements to ensure safe and compliant transport.

Q: Can caustic soda be used in food or pharmaceutical applications?

A: This product is of industrial grade and intended solely for industrial applications such as manufacturing, cleaning, and water treatment. It is not suitable for food or pharmaceutical use due to its purity specification and manufacturing processes.

Q: What advantages does using caustic soda in industrial processes provide?

A: Caustic soda delivers potent alkalinity, rapid solubility in water, and efficient removal of oils, grease, or contaminants, enhancing manufacturing and cleaning processes. Its versatility speeds up chemical reactions and supports a broad spectrum of industrial operations, contributing to process efficiency and product quality.
