Meet stringent industrial purity standards with our Solid Caustic Soda 96-99% Purity. This high-grade solid sodium hydroxide is refined through multi-stage evaporation and purification processes, delivering minimal impurity content within 96% to 99% NaOH range. Available in flake, pearl and granular forms, it is engineered for manufacturing processes sensitive to contaminants, where consistent high alkalinity and low foreign substance levels are non-negotiable.

High Purity Grade & Key Performance Advantages

Our 96~99% solid caustic soda stands out among alkali products for its low impurity profile, ideal for industries that cannot tolerate excess salts or heavy metals. Solid Caustic Soda 96-99% Purity brings these core strengths:

• Strictly Controlled Impurities: Low chloride, iron and heavy metal contents. Eliminates unwanted side reactions and protects product quality in sensitive chemical synthesis.

• High Active Alkali Content: 96%–99% caustic soda assures strong, reliable alkalinity. Less dosage is required compared to lower-purity alternatives, optimizing raw material consumption.

• Controlled Dissolution Behavior: Dissolves steadily in water. Users can prepare precise alkaline solutions for recipes requiring accurate pH and concentration control.

Target Sectors for 96-99% High Purity Solid Caustic Soda

The low-impurity feature makes our solid caustic soda 96-99% purity suitable for premium-grade production:

• Fine Chemical & Pharmaceutical Intermediates: High-purity base for hydrolysis, condensation and neutralization reactions for medicine and specialty chemical manufacturing.

• High-Grade Soap & Cosmetic Raw Materials: Low heavy metal content meets requirements for premium soap, surfactant and cosmetic raw material production.

• Water Treatment for Ultra-Pure Water Systems: Used in ion exchange resin regeneration and pH adjustment for high-purity water projects.

• Food Additive Processing: Compliant grades available for food processing, vegetable peeling and food container cleaning.

• Advanced Textile Mercerization: For high-end cotton fabric treatment to boost fabric luster and strength.

Sealed Packaging & Storage Guidelines

High purity solid caustic soda readily absorbs moisture and carbon dioxide from ambient air, which will reduce its effective purity. Dry, sealed storage and low-humidity warehouse conditions are mandatory.

Our Solid Caustic Soda 96-99% Purity is packed in 25kg multi-layer woven bags with inner PE liners for moisture barrier. All packages carry UN dangerous goods marks and hazard information to support hassle-free sea freight and customs clearance.
