Sodium Benzoate (E211)

Description

1. Product Overview
   Sodium Benzoate (E211) is a high-purity sodium salt of benzoic acid used globally as an effective preservative and corrosion-inhibiting agent. Primarily applied across food and beverage preservation, personal-care formulations, and industrial corrosion control, it prevents microbial growth and extends product shelf life under acidic conditions. Our offering delivers consistent, specification-driven performance that reduces spoilage, minimizes recall risk, and supports regulatory compliance in diverse markets. For procurement teams, Sodium Benzoate (E211) represents a low-cost, proven ingredient that materially improves product stability and supply-chain resilience.

2. Key Specifications & Technical Characteristics

• Appearance: White to off-white crystalline powder.

• Form & particle size: Free-flowing granules or fine powder; particle size distribution supplied on request.

• Odor & taste: Slight characteristic odor; near tasteless at recommended use levels.

• Solubility: Readily soluble in water; solubility increases with temperature.

• pH (1% aqueous solution): Typically acidic to near-neutral; exact range provided on SDS.

• Bulk density: Typical range 450–650 kg/m³ (packed density varies by packaging).

• Moisture content: ≤ 0.5% (typical specification).

• Chloride / sulfate residues: Conforms to regulatory limits for food/industrial grades.

• Packaging options: 25 kg multi-layer kraft paper bags with polyethylene inner liner; 500 kg / 1,000 kg FIBCs (big bags); 20 MT bulk in ISO tank options for liquid/dispersion forms where applicable.

• Shelf life: 24 months when stored in original sealed packaging in a cool, dry place away from strong oxidizers and moisture.

• Compliance documentation: Certificate of Analysis (CoA), Safety Data Sheet (SDS), and regulatory declarations (FG, E-number E211) provided per shipment.

3. Core Industrial Applications

• Food & Beverage: Widely used as a preservative in acidic products (soft drinks, fruit juices, pickles, sauces, dressings) to inhibit yeast and bacterial growth, enabling longer shelf life and reduced waste.

• Personal Care & Cosmetics: Preservative in shampoos, lotions, and cosmetics where pH and formulation compatibility require benzoate chemistry.

• Pharmaceutical Excipients: Stabilizer and preservative in selected oral liquid formulations and topical preparations, compliant with pharmacopeial standards when specified.

• Industrial & Chemical: Corrosion inhibitor in lubricants, antifreeze formulations, and metalworking fluids; intermediate for organic synthesis.

• Water Treatment & Adhesives: Used in specific formulations to control microbial activity during storage and use.
  Why it outperforms alternatives:

• Cost-efficiency: Lower cost-in-use compared with some broad-spectrum preservatives, especially in acidic matrices.

• Proven efficacy: Decades of regulatory approval and robust performance data in targeted pH ranges (typically effective at pH ≤ 4.5).

• Compatibility: Minimal interaction with many common formulation chemistries, simplifying formulation and scale-up.

4. Competitive Advantages

• Quality consistency: Batch-to-batch assays and CoAs ensure purity and functional performance at scale.

• Supply reliability: Established raw-material sourcing and production schedules designed to support continuous supply for large industrial buyers.

• Logistics capability: Flexible packaging (25 kg bags, FIBC, bulk ISO/tank options) and containerized loading optimized for port throughput and inland distribution.

• Price competitiveness: Economies of scale and regional distribution reduce landed cost versus smaller suppliers.

• Sustainability: Storage-stable solid form minimizes transport weight/volume; supplier can provide material origin details for ESG reporting.

• Technical support: Dedicated regulatory and technical documentation, including SDS, CoA, handling guidelines, and formulation support on request.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): BULK 20MT.

• Typical container loading: Up to 20 MT per 20-foot container for bagged product; up to ~24–25 MT per 20-foot container depending on packaging and pallet configuration (confirm at time of booking).

• Lead times: Subject to confirmation at order; typical lead time for bulk orders 2–6 weeks depending on destination and current inventory.

• Incoterms & logistics: FOB/CIF/EXW options available; consolidated shipping and export documentation provided.

• Documentation: CoA, SDS, packing list, commercial invoice, and certificate of origin available per shipment.
