What Is Caustic Soda?
Caustic soda, also known as sodium hydroxide (NaOH), is a strong alkaline chemical used in many industries, including:
- – Water treatment
- – Mining
- – Soap and detergent manufacturing
- – Paper and pulp production
- – Food processing
- – Chemical manufacturing
It is available in three main forms:
- – Flakes
- – Pearls (beads)
- – Liquid
Each form serves different operational needs.

Caustic Soda Flakes: High Purity for Precision
Caustic soda flakes are thin, solid pieces with 98–99% purity. They dissolve quickly in water and are ideal for applications that require accuracy.
Key Benefits
- – High chemical purity
- – Easy to measure
- – Ideal for pharmaceuticals and chemical processing
Things to Consider
- – Absorbs moisture from air
- – Can clump if not stored properly
- – Requires PPE due to high reactivity
Flakes are commonly used in chemical manufacturing and industrial cleaning.
Caustic Soda Pearls: Easy Handling, Less Dust
Caustic soda pearls are small, round beads made for easier handling and cleaner working conditions.
Key Benefits
- – Lower dust levels
- – Smooth flow for automated systems
- – Accurate dosing
Things to Consider
- – Still absorbs moisture
- – Needs airtight storage
- – Requires safety gear
Pearls are widely used in detergent production, textile processing, and water treatment.

Liquid Caustic Soda: Ready-to-Use Convenience
Liquid caustic soda is sodium hydroxide already dissolved in water, usually at 20%–50% concentration.
Key Benefits
- – No dissolving needed
- – Easy pumping and metering
- – Ideal for large-scale operations
Things to Consider
- – Highly corrosive
- – Requires special storage tanks
- – Needs spill control systems
