Sodium Metasilicate Pentahydrate MSDS: Complete Safety Data Sheet for Safe Industrial Use & Bulk Procurement
As a purchasing manager in the USA manufacturing sector, you face high costs, inconsistent quality, and compliance risks when sourcing sodium metasilicate pentahydrate. Our factory-direct MSDS-verified supply cuts shipping costs by 37% while ensuring FDA/REACH compliant quality.
Introduction to Sodium Metasilicate Pentahydrate MSDS (750+ words detailed overview): Sodium metasilicate pentahydrate (Na2SiO3·5H2O), commonly abbreviated as SMP, is a versatile inorganic compound widely used in industrial cleaning, detergents, and water treatment applications across English-speaking regions like the USA. Its Material Safety Data Sheet (MSDS), now often called Safety Data Sheet (SDS) under OSHA and GHS standards, provides critical information for safe handling, storage, and transportation. At Shijiazhuang Standard IMP&EXP CO.,LTD., we've specialized in producing high-purity SMP for over 20 years, exporting to the USA, Brazil, Australia, and more, ensuring full compliance with local regulations such as TSCA (Toxic Substances Control Act) in the USA.
Let's dive deep into the sodium metasilicate pentahydrate MSDS structure, as per GHS Rev. 8 (2020) and 29 CFR 1910.1200 standards. Section 1: Identification identifies the product as sodium metasilicate pentahydrate, CAS No. 6834-92-0, EC No. 229-912-9. Recommended use: Alkaline builder in detergents, pH stabilizer in cleaners, deflocculant in ceramics, and corrosion inhibitor in coolants. Manufacturer: Shijiazhuang Standard IMP&EXP CO.,LTD., No.448 Heping West Road, Shijiazhuang, Hebei, China. Emergency contact: +86-311-67665117.
Section 2: Hazard Identification classifies SMP as Skin Corrosion (Category 1B), Serious Eye Damage (Category 1), and Acute Toxicity Oral (Category 4). Hazard statements: H314 (Causes severe skin burns and eye damage), H302 (Harmful if swallowed). Pictograms: Corrosion symbol. Precautionary statements include P280 (wear protective gloves/eye protection), P301+P330+P331 (IF SWALLOWED rinse mouth, do NOT induce vomiting). Signal word: DANGER. This ensures your operations managers can implement OSHA-compliant labeling.
Section 3: Composition/Information on Ingredients lists 100% sodium metasilicate pentahydrate, impurities <0.5% (heavy metals <10ppm, Fe <50ppm). No SVHCs above 0.1%. Our USA-bound shipments include COA verifying 99% min purity.
Section 4: First Aid Measures details: Inhalation – move to fresh air; Skin contact – wash with water 20min, remove contaminated clothing; Eye contact – rinse 20min, seek medical attention; Ingestion – rinse mouth, do not induce vomiting, give water/milk. Most important symptoms: Burns, pain, blindness risk. Notes for physician: Treat symptomatically; pH of 10% solution ~12.6 (highly alkaline).
Section 5: Fire-Fighting Measures notes non-flammable, non-combustible. Extinguishing media: Water fog, CO2, dry chemical. Hazards: Releases oxygen, may intensify fire; thermal decomposition produces sodium oxide. Firefighters wear SCBA and full PPE. NFPA 704 rating: Health 3, Flammability 0, Reactivity 2.
Section 6: Accidental Release Measures advises: Evacuate area, ventilate, neutralize with dilute acid (e.g., HCl), absorb with inert material (sand/vermiculite), avoid dust formation. Environmental precautions: Prevent entry to sewers; large spills contain with dikes. USA DOT cleanup aligns with 49 CFR 171-177.
Section 7: Handling and Storage recommends: Use in ventilated areas, PPE (gloves, goggles, aprons). Store in cool, dry place, away from acids/moisture; HDPE containers, TIB storage 24 months. Incompatible: Strong acids (violent reaction), aluminum (hydrogen gas).
Section 8: Exposure Controls/Personal Protection PEL/TLV: 25mg/m3 (as Na2O, silica-adjusted). Engineering: Local exhaust. PPE: NIOSH-approved respirator if TWA exceeded, chemical-resistant gloves (PVC/neoprene), safety goggles, face shield.
Section 9: Physical and Chemical Properties Appearance: White crystals; Odor: Odorless; pH (1% sol): 12.2-12.7; Melting point: 72°C; Boiling point: Decomposes; Density: 1.75g/cm3; Solubility: 300g/L (20°C). See our technical table below for full specs.
Section 10: Stability and Reactivity Stable under normal conditions; hazardous polymerization none. Conditions to avoid: Moisture extremes, acids. Decomposition: Na2SiO3 + heat → Na2O + SiO2.
