Sodium Benzoate (E211)

Description

1. Product Overview
   Sodium Benzoate (E211) is the sodium salt of benzoic acid and a widely used food-grade and industrial preservative. In industrial settings it functions as an antimicrobial and preservative agent, corrosion inhibitor, and chemical intermediate. Its primary value proposition is reliable, cost-effective microbial control and formulation stability across fluids and solids, enabling longer shelf life and consistent product performance. Strategically, Sodium Benzoate (E211) is a high-demand, low-complexity commodity chemical essential to food & beverage, personal care, pharmaceuticals, and industrial formulations where regulatory compliance and supply continuity are critical.

2. Key Specifications & Technical Characteristics

• Chemical composition: Sodium benzoate (C7H5NaO2).

• CAS number: 532-32-1.

• Purity/grade: Food grade / E211 specification, typical purity ≥ 99.0% (adjustable to customer spec).

• Assay: ≥ 99.0% (typical), impurity profile conforms to relevant pharmacopeia/food additive standards on request.

• Physical form: White crystalline powder or granules.

• Color: White to off-white.

• Odor: Characteristic faint benzoic odor.

• Particle size: Standard powder mesh (custom sieving available per order).

• Bulk density: Typical tapped density 450–650 kg/m3 (batch-dependent).

• Solubility: Freely soluble in water, limited solubility in ethanol.

• pH (1% aqueous solution): ~7.5–9.0 (depends on concentration).

• Moisture content: Typically ≤ 0.5% (controlled).

• Packaging options: 25 kg multi-ply kraft bags with polyethylene liner, 500 kg and 1000 kg FIBC (big bags), and 20 MT bulk palletized or loose in ISO tank/truck.

• Storage/shelf life: Store in cool, dry, well-ventilated area away from strong oxidizers; typical shelf life 24 months when stored under recommended conditions.

• Regulatory: Conforms to E211 food additive designation; documentation available (COA, MSDS/SDS, Certificate of Analysis, regulatory compliance dossiers on request).

3. Core Industrial Applications

• Food & Beverage: Preservative in acidic foods and beverages (soft drinks, sauces, jams) to inhibit yeast and bacteria, extending shelf life while maintaining flavor and safety.

• Personal Care & Cosmetics: Preservative in lotions, creams, and water-based formulations where pH and compatibility favor benzoate chemistry.

• Pharmaceuticals: Excipient and preservative in select formulations; used as intermediate in synthesis routes.

• Industrial Formulations & Corrosion Control: Corrosion inhibition in coolant and lubricant formulations, and as a component in industrial aqueous systems requiring microbial control.

• Chemical Manufacturing: Intermediate for synthesis of benzoic acid derivatives and other specialty chemicals.
  Why it outperforms alternatives:

• Efficacy at low concentration in acidic environments enables cost-effective dosing.

• Broad regulatory acceptance (E211) simplifies formulation approval for food & beverage and personal care manufacturers.

• High solubility and stable crystalline form facilitate accurate dosing and handling in automated production lines.

4. Competitive Advantages

• Quality consistency: Tight batch-to-batch assay control, full COA provided with every shipment.

• Supply reliability: Multiple production sources and inventory management optimized for uninterrupted supply to industrial buyers.

• Logistics capability: Flexible packaging and container-loading options (FIBC, palletized 25 kg bags, bulk), experienced handling for export and hazardous/regulated shipments.
