About this product

Caustic Soda Flakes & Pearls (Sodium Hydroxide) — product overview

Anhydrous caustic soda (sodium hydroxide, NaOH) in flake and pearl forms for industrial use. Typical downstream applications include pulp and paper processing, industrial water neutralisation and chemical synthesis. UN-approved poly-bag packaging is used for transport. Because NaOH is a category-J bulk industrial chemical and reactive to moisture, packaging, storage guidance and shipping documentation are confirmed per shipment; SDS is provided against the specific grade and origin supplied. Purity, particle form (flake vs pearl) and batch COA are confirmed at quotation.

Document & COA status
  • • TDS: Displayed properties are an Allzone technical reference; manufacturer documentation is available on request.
  • • SDS: Safety data is subject to grade and supplier confirmation. One SDS does not necessarily apply to every grade or supplier.
  • • COA: Certificate of Analysis is provided against the confirmed shipment, grade and batch. No stock, lead-time or regulatory claim is implied without written confirmation.

§ 3Composition / Information on Ingredients
▾
Mixture
Engineered bulk industrial chemicals based caustic soda flakes & pearls (sodium hydroxide).
Carrier
Bulk Industrial Chemicals compatible polymer.
Sodium hydroxide (CAS 1310-73-2)
≥ 99 %
§ 4First Aid Measures
▾
Inhalation
Move to fresh air. Get medical advice if discomfort persists.
Skin contact
Immediately remove contaminated clothing. Rinse skin with copious amounts of water for at least 30 minutes. Seek immediate medical attention. Risk of severe chemical burns.
Eye contact
Rinse cautiously with water for at least 15 minutes, holding eyelids open. Remove contact lenses if present. Seek immediate medical attention.
Ingestion
DO NOT induce vomiting. Rinse mouth and give plenty of water. Seek immediate medical attention.
Hot melt burns
For pellet-form products processed at melt temperature: cool affected area with cold water. Do NOT peel solidified polymer from skin — seek medical attention.
§ 5Fire-Fighting Measures
▾
Suitable extinguishing media
Dry chemical, CO2, alcohol-resistant foam. AVOID water on dry product (exothermic reaction).
Unsuitable media
Water jet on dry material — generates heat and may splatter caustic solution.
Special hazards
Combustion may produce CO, CO2 and dense black smoke. Polymer melt drips during fire.
PPE for firefighters
Self-contained breathing apparatus (SCBA) and full protective gear.
§ 6Accidental Release Measures
▾
Personal precautions
Wear PPE per Section 8. Avoid generating dust. Ventilate area.
Environmental precautions
Prevent entry into drains, waterways or soil. Notify authorities if significant release.
Cleanup
Carefully sweep or vacuum (HEPA). Neutralize residue with dilute acid. Collect in labelled hazardous-waste container.
§ 7Handling & Storage
▾
Handling
Use only in well-ventilated areas. Wear full chemical-resistant PPE. Add to water slowly — never the reverse.
Storage
Store in tightly closed original container in a cool, dry, well-ventilated area. Segregate from acids, metals (Al, Zn), and ammonium salts.
Incompatible materials
Acids, aluminum, zinc, tin, ammonium compounds, organic halogens, nitromethane.
§ 8Exposure Controls / Personal Protection
▾
Engineering controls
Local exhaust ventilation at material transfer and melt-processing points. Maintain dust below regional OEL.
Respiratory protection
N95 / P2 dust mask minimum; full-face respirator if dust exposure exceeds OEL.
Hand protection
Chemical-resistant gloves (neoprene, nitrile, butyl rubber).
Eye protection
Safety glasses with side shields; chemical splash goggles when handling powders or molten material.
