CAS 1310-73-2

Caustic soda pearls (molecular formula NaOH), also referred to as pearl-form sodium hydroxide, are spherical-bead inorganic strong-alkali solids produced by melt-spray granulation. Compared with flaky caustic soda, this bead-form solid alkali features uniform particle size, good free-flowing behaviour and minimal dust generation. It is a fundamental inorganic chemical raw material widely used in water treatment, textiles, pulp and paper, detergent manufacturing, and fine-chemical synthesis.

This solid-alkali material gains its practical processing advantages primarily from its distinctive spherical-bead physical morphology created by melt-granulation technology. Consistent bead-size distribution delivers excellent flow characteristics, supporting stable feeding for automated batching equipment. Meanwhile, it generates far fewer fine particulates during manual or mechanical material transfer, lowering operator exposure risks relative to flake-form caustic soda. As a typical strong inorganic alkali, caustic soda pearls dissolve vigorously in water and release significant dissolution heat; its aqueous solution exhibits powerful neutralising capacity toward a broad range of acidic substances. However, the material is highly hygroscopic. It readily absorbs moisture and carbon dioxide from ambient air and degrades by forming sodium-carbonate impurities without adequate sealing during storage.

Commercial-grade caustic soda pearls are available in industrial-grade and food-grade specifications. Industrial-grade material typically reaches ≥99 % NaOH content and applies to wastewater pH adjustment, textile mercerisation, pulping processes, soap-and-detergent saponification, and general inorganic-synthesis workflows. Food-grade caustic soda pearls enforce stricter limits on heavy-metal and trace-impurity levels to meet relevant food-additive standards. It may be utilised in food-processing operations such as fruit-and-vegetable peeling and sugar refining. Unlike flake caustic soda, pearl-form material resists caking during transport and sealed storage. It maintains consistent dissolution rates when added to aqueous systems, enabling factories to achieve repeatable solution concentrations across batch-to-batch production. This corrosive alkali must be kept away from direct skin or eye contact and from aluminium-alloy components throughout all-handling workflows.

As a trusted chemical supply-chain provider, we implement strict quality-control protocols for caustic soda pearls. Our various grades maintain stable main-component assays with closely monitored chloride, heavy-metal and carbonate impurity parameters. Mature melt-granulation, screening and moisture-proof sealed-packaging procedures minimise batch-to-batch variation. Consistent physicochemical specifications prevent quality drift that would otherwise lead to unstable pH-regulation effects or non-compliant end-products for downstream manufacturing customers.

Purchasers gain tangible practical benefits by choosing our supply. First, consistent product specifications reduce repeated incoming-material laboratory testing for your technical teams and cut raw-material waste during continuous large-scale batching-based production. Second, we provide comprehensive export-oriented documentation including COA and MSDS to streamline cross-border customs clearance and corporate safety-audit workflows. Third, moisture-resistant sealed packaging supports small-scale trial-batch orders as well as high-volume bulk-industrial procurement. Our technical team can share practical guidance on storage, feeding techniques and corrosion-protection precautions when customers encounter real-world production challenges.

We fully understand overseas buyers' core concerns around product stability, document completeness and safe transportation. Store this highly hygroscopic corrosive solid in hermetically-sealed moisture-proof containers within cool, dry, well-ventilated warehouse premises. Isolate it from humid air, carbon-dioxide-rich atmospheres, acids, aluminium and amphoteric-metal items to prevent chemical degradation and hazardous reactions. Operators must wear appropriate PPE including alkali-resistant gloves, goggles and protective clothing for all material-handling tasks. Every shipment undergoes pre-shipment inspection prior to dispatch. We have extensive export experience for basic inorganic-alkali chemicals and maintain long-term stable partnerships with water-treatment, textile and fine-chemical manufacturers worldwide. This proven track-record demonstrates our reliable supply capabilities.
