What is Caustic Soda Pearl?
Chemical Structure and Characteristics
Caustic soda pearl, chemically known as sodium hydroxide (NaOH), is a solid, white, bead-like form of caustic soda. These pearls are highly soluble in water, generating significant heat upon dissolution. They are extremely alkaline and react strongly with acids, making them ideal for neutralization, cleaning, and processing tasks.
These NaOH pearls are manufactured through an advanced evaporation and granulation process, resulting in uniform, spherical particles with very low moisture content. The product typically has a purity of ≥99%, making it suitable for critical industrial operations where consistency and safety are vital.
How Pearls Differ from Flakes or Liquid NaOH
Caustic soda pearls offer several advantages over other forms:
-
Higher Bulk Density: Easier to handle and more compact storage.
-
Lower Dust Generation: Safer handling in dry environments.
-
Extended Shelf Life: More stable over time when properly stored.
-
Precise Dosing: Controlled dissolving for high-accuracy industrial processes.
At New Indureg Chemicals, we supply high-purity caustic soda pearls suitable for use in water treatment, petrochemical, textile, and detergent industries.
Applications of Caustic Soda Pearl in Industry
Detergents, Soap, and Surfactants
Caustic soda pearls play a fundamental role in the formulation of detergents and soaps. Their high alkalinity is crucial for saponification—the reaction between fats and alkalis to form soap.
In large-scale cleaning product manufacturing, pearls are preferred due to their:
-
Fast dissolution in mixing tanks
-
Uniform particle size for measured batching
-
Minimal dusting, ensuring cleaner production environments
Common uses include:
-
Household and industrial cleaners
-
Dishwashing detergents
-
Fabric softeners and emulsifiers
Oil Refining and Petrochemical Processing
In the petrochemical sector, caustic soda pearls are used to remove acidic impurities like hydrogen sulfide and fatty acids from crude oil and derivatives. This process, known as caustic washing, helps refine fuels and improves product stability.
Applications include:
-
Degumming of vegetable oils
-
Production of biodiesel
-
Processing of petroleum-based lubricants and additives
Due to their concentrated form and high purity, pearls ensure greater operational control and reduced waste during refining stages.

Caustic Soda Pearls in Water Treatment and Textile Industries
Role in Wastewater pH Correction
Caustic soda pearls are heavily used in municipal and industrial water treatment processes. Their function is to neutralize acidic wastewater, allowing for:
-
Safe discharge into the environment
-
Enhanced flocculation and sedimentation of impurities
-
Regeneration of ion-exchange columns in water softeners
The pearl form dissolves quickly, giving operators precise pH control and predictable chemical behavior.
Mercerization and Fiber Processing in Textiles
In textile finishing, sodium hydroxide pearls are used during the mercerization process, where cotton and cellulose-based fibers are treated to improve:
-
Tensile strength
-
Dye uptake and brilliance
-
Fabric luster and dimensional stability
New Indureg Chemicals supplies textile-grade NaOH pearls to garment manufacturers and fabric processors across Belgium and the EU.
Handling, Storage, and Safety Measures
Worker Protection and Usage Guidelines
Because of their high corrosiveness, caustic soda pearls must be handled with care. Direct contact can result in severe chemical burns, respiratory irritation, or eye damage.
Safety protocols include:
-
Nitrile or neoprene gloves
-
Chemical goggles and face shields
-
Ventilated storage and work areas
-
Emergency eyewash and neutralization stations
Always use non-metallic containers for mixing, as sodium hydroxide reacts with aluminum, zinc, and some alloys.
Packaging and Long-Term Storage Instructions
New Indureg Chemicals delivers caustic soda pearls in:
-
25 kg PE-lined bags
-
500 kg to 1-ton jumbo sacks
-
Sealed pallets for export and long-term storage
Store in dry, well-ventilated spaces, away from:
-
Moisture (to prevent hardening and reaction)
-
Acids and oxidizing agents
-
Organic materials and flammable liquids
When properly stored, NaOH pearls have a shelf life exceeding 24 months without loss of potency.
