Pure Sodium Hydroxide Pellets | 99% Pure Caustic Soda

Key Product Advantages

• Ultra-High 99% Purity: Delivers maximum chemical reactivity, high assay performance, and reliable batch-to-batch consistency. Engineered with minimal trace impurities—specifically controlled iron, sodium chloride, and heavy metal content—this high-assay material ensures predictable reaction kinetics, prevents unreacted residue, and completely eliminates undesirable side reactions in delicate cosmetic formulations, specialized chemical synthesis, and commercial soap manufacturing lines.

• Rapid & Uniform Dissolution: Features a consistent, low-dust pellet structure designed for superior flowability, high density, and non-caking behavior. The solid pellets dissolve rapidly and completely in water through a strongly exothermic reaction, releasing thermal energy that speeds up batch mixing cycles, accelerates solution preparation times, and ensures homogeneous alkalinity across automated dosing systems.

• Moisture-Lock Protective Packaging: Shipped in airtight, heavy-duty, multi-layer moisture-barrier containers that completely isolate the material from ambient air. This specialized packaging shields the highly hygroscopic solid against atmospheric humidity, water vapor, and carbon dioxide (CO2) absorption, successfully preventing premature clumping, deliquescence, surface crusting, and chemical degradation during long-distance transportation and extended warehouse storage.

Primary Industrial & Laboratory Applications

• Soapmaking & Cosmetic Manufacturing: Serves as the essential strong alkaline reactant for saponifying vegetable oils, animal fats, and fatty acid bases. It provides the accurate stoichiometric control required for both cold-process and hot-process soapmaking, yielding firm, high-quality solid soap bars, smooth liquid soap stocks, and stable surfactant bases without leaving unreacted free caustic.

• Heavy-Duty Industrial & Home Cleaning: Functions as a powerful caustic cleaning agent that rapidly hydrolyzes fats, breaks down tough proteinaceous soils, and dissolves stubborn organic buildup, hair, and grease. It is widely used in heavy-duty drain maintenance, main pipe clearing, industrial degreasing, and automated Clean-in-Place (CIP) equipment sanitation systems.

• Chemical Manufacturing & Processing: Widely deployed as a foundational strong inorganic base in biodiesel transesterification reactions, textile fiber mercerization, wood pulp delignification, organic intermediate synthesis, and precise pH adjustment and neutralization in municipal and industrial wastewater treatment facilities.

Safe Handling & Usage Guidelines

Sodium hydroxide is a strong, highly corrosive inorganic base that poses severe chemical burn hazards to human skin and eyes upon direct contact. Operators must always wear full protective equipment, including splash-proof chemical goggles, heavy-duty face shields, chemical-resistant nitrile or neoprene gloves, long-sleeved workwear, and protective rubber aprons.

Critical Safety Protocol: Always add solid sodium hydroxide to water slowly—never pour water directly onto solid sodium hydroxide. Adding water to solid caustic soda can cause localized boiling, violent thermal expansion, hazardous exothermic heat spikes, and dangerous corrosive splashing. Always perform mixing routines in well-ventilated areas using heat-resistant, alkali-compatible containers (such as high-density polyethylene/HDPE or high-grade stainless steel) while avoiding contact with reactive metals such as aluminum, zinc, brass, or tin.
