Sodium Bicarbonate (E500)

Description

1. Product Overview

Sodium Bicarbonate (E500) is a high-purity, industrial-grade alkaline salt widely used across chemical, food, pharmaceutical, and environmental industries. Primarily employed as a pH regulator, neutralizing agent, buffering component, and mild abrasive, it provides predictable, safe alkalinity control in large-scale processes. The product delivers consistent performance, easy handling, and cost-efficient dosing — reducing process variability and downstream treatment costs. Strategically, Sodium Bicarbonate (E500) is a low-risk, high-utility raw material that supports regulatory compliance, process stability, and scalable supply for industrial buyers.

2. Key Specifications & Technical Characteristics

• Physical form: Fine to granulated crystalline powder; free-flowing.

• Color: White to off-white.

• Particle size: Typical D50 range 50–250 µm (custom milling available).

• Bulk density: Approx. 600–800 kg/m3 (tamped and untamped values available).

• Solubility: ~9.6 g/100 mL water at 20°C (for dosing calculations).

• pH (1% aqueous): ~8.3–8.5 (buffering characteristics noted).

• Moisture content: Controlled to customer specification, typically <0.5% w/w.

• Packaging options:

  • 25 kg polyethylene-lined multiwall paper bags, palletized (T1).

  • 500–1000 kg bulk bags (FIBC), heat-sealed liner options (T2).

  • Loose bulk for ISO tank / pneumatic tanker loading (subject to logistics).

• Shelf life: Stable under dry storage; recommended use within 24 months when stored <30°C and protected from humidity.

• Documentation: Certificate of Analysis (COA), Safety Data Sheet (SDS), GMP/food-contact statements available upon request.

3. Core Industrial Applications

• Water & Wastewater Treatment: pH correction and buffering in municipal and industrial systems; effective, safer alternative to caustic soda for neutralization and odor control.

• Flue Gas Treatment & Emissions Control: Dry/wet scrubbing of acid gases (SO2, HCl) where predictable alkalinity and low risk of over-alkalinization are required.

• Chemical Manufacturing: Intermediate for carbonate/bicarbonate chemistries, neutralization in syntheses, and controlled-release alkalinity in batch processes.

• Food & Beverage: Leavening agent, acidity regulator, and processing aid in baked goods and beverage formulations (when food-grade E500 is specified).

• Pharmaceutical & Personal Care: pH adjustment in formulations, effervescent products, and mild abrasive cleaning agents; compatible with GMP workflows.

• Mining & Metallurgy: Ore flotation pH control, reagent buffering, and dust suppression where soluble, low-toxicity alkalinity is needed.

• Detergents & Cleaners: Formulation ingredient providing mild alkalinity and buffering, improving cleaning performance while minimizing corrosion.
  Why it outperforms alternatives:

• Safety: Lower handling risk and corrosivity vs. sodium hydroxide or potassium hydroxide.

• Cost-efficiency: Competitive bulk price per unit alkalinity with reduced need for corrosion-resistant equipment.

• Process control: Predictable buffering capacity reduces titration variability and waste treatment load.

4. Competitive Advantages

• Quality consistency: Tight in-house QC with per-batch COAs ensures assay and impurity repeatability for regulated supply chains.

• Supply reliability: Secure manufacturing sources and multi-origin procurement minimize disruption risk; scalable production to meet large contracts.

• Logistics capability: Flexible packaging (bags, FIBC, bulk) and bulk-loading options support containerized or bulk tanker shipments; local warehousing options for JIT delivery.

• Price competitiveness: Economies of scale for 20 MT+ bulk orders reduce landed cost; transparent pricing models for long-term contracts.

• Sustainability: Inert, non-toxic profile with options for manufacturing from low-carbon process streams; recyclable packaging options available.

• Technical support: Application guidance, dosing calculations, COA/SDS provision, and on-request process trials or sample shipments to validate fit.

5. Commercial & Supply Information
