What Is Caustic Soda Pearls?

Caustic Soda Pearls, also known as Sodium Hydroxide Pearls (NaOH), are a solid form of sodium hydroxide manufactured into small, uniform white pearls. Compared with liquid caustic soda, the pearl form has a high active content and is convenient for storage, transportation, and accurate dosing.

Applications
  • Chemical Industry: Raw material and processing agent for various sodium salts and organic intermediates.
  • Pharmaceutical Industry: Equipment cleaning, pH adjustment and selected manufacturing processes (confirm grade requirements).
  • Food Processing: Used in specific food-processing tasks such as peeling and cleaning; confirm regulatory requirements for food use.
  • Petroleum Refining: Treatment of acidic components and impurity removal.
  • Pulp and Paper: Pulping, chemical treatment and recovery processes.
  • Detergents: Manufacture of soaps, detergents and industrial cleaning products.
  • Fine Chemicals: Alkaline reagent and pH regulator in fine chemical production.
Caustic Soda Pearls vs. Liquid Caustic Soda

Caustic soda is available as pearls, flakes and liquid solutions. Pearls provide a high concentration of active NaOH in a solid form, convenient for transportation and storage. For long-distance shipments and flexible dosing, 99% caustic soda pearls are often preferred.

Packaging and Storage

Normally supplied in moisture-resistant bags suitable for international transport. Store in a cool, dry and well-ventilated area, protected from moisture and incompatible materials. Sodium hydroxide is highly corrosive; use appropriate PPE and follow the SDS.

Frequently Asked Questions (FAQ) – Caustic Soda Pearls
What are Caustic Soda Pearls?

Caustic Soda Pearls are a solid form of sodium hydroxide (NaOH) manufactured into small, white, uniform pellets. They provide a high active content and are convenient for storage, transport and accurate dosing.

What is the CAS number of Sodium Hydroxide?

The CAS number for sodium hydroxide is 1310-73-2.

What is the typical purity of Caustic Soda Pearls?

Typical specification is ≥ 99.0% NaOH. Other limits: Na₂CO₃ ≤ 0.8%, NaCl ≤ 0.1%, Fe ≤ 0.005% (see TDS/COA for full details).

What are the main applications?

Common applications include chemical manufacturing, pulp & paper, detergents, water treatment, petroleum refining, food processing (where permitted), and various industrial cleaning processes.

Are Caustic Soda Pearls hazardous?

Yes. Sodium hydroxide is strongly corrosive and can cause severe burns. Follow the SDS, use appropriate PPE (gloves, eye protection, protective clothing) and ensure safe handling and storage practices.

What is the difference between pearls and liquid caustic soda?

Pearls are a concentrated solid form that is easier to transport and dose; liquid caustic (sodium hydroxide solution) is aqueous and may be preferred for some processes. Choice depends on handling, dosing and process requirements.

Can Caustic Soda Pearls be used in food processing?

Some food processing operations (e.g., peeling, cleaning) use sodium hydroxide, but compliance with local food regulations and specific grade requirements must be confirmed before use.

How should Caustic Soda Pearls be packaged and stored?

Typically supplied in moisture-resistant bags (25kg/50kg) or larger bulk packs. Store in a cool, dry, ventilated area away from moisture and incompatible materials. Keep containers tightly closed.

Do you provide TDS, COA and SDS?

Yes. Technical documents including TDS, COA and SDS are available on request to support quality control and regulatory compliance.
