Potassium Phosphate (E340)

Description

1. Product Overview
   Sodium Phosphate (E339) is a high-purity inorganic phosphate salt supplied for industrial-scale formulations and process applications. It functions as a buffering agent, sequestrant, and emulsifier across chemical processing, food ingredient manufacturing, water treatment, and surface treatment operations. The product delivers consistent physicochemical properties that enable process stability, predictable reaction control, and regulatory conformity where applicable. For strategic buyers, Sodium Phosphate (E339) is a low-risk, high-utility raw material that simplifies formulation, reduces downstream variability, and supports scalable production and supply-chain resilience.

2. Key Specifications & Technical Characteristics

• Chemical name: Sodium Phosphate (E339), typically present as monosodium, disodium, or a blend depending on grade and specification.

• Chemical formula: NaxHyPO4 (specify grade sheet for exact species distribution).

• Purity / grade: Industrial / Food-grade options available; typical purity range 98.0–99.5% (confirm with certificate of analysis).

• Assay basis: Percentage expressed on dry basis per supplied COA.

• Physical form: Free-flowing crystalline powder or granules.

• Color: White to off-white.

• Particle size: Typically D90 ≤ 300–500 µm (custom milling available on request).

• Bulk density: Approx. 0.8–1.2 g/cm³ (varies by granule size and moisture).

• Moisture content: ≤ 1.0–2.0% typical (grade dependent).

• pH (aqueous solution): Buffering behavior dependent on species; refer to technical datasheet.

• Solubility: Readily soluble in water; solubility varies by sodium phosphate species and temperature.

• Impurities: Heavy metals and relevant ion limits per applicable standards; supplied with COA.

• Packaging options: 25 kg kraft paper bags with polyethylene liner; 500–1,000 kg bulk bags (FIBC); 20 MT bulk in ISO or flexitanks; packed and palletized for container shipping.

• Shelf life / storage: Recommended 24 months when stored dry, in a sealed container, away from moisture and direct sunlight.

3. Core Industrial Applications

• Food & Beverage (where food-grade): Buffering, emulsifying, sequestrant in processed foods, dairy, and beverage formulations; aids texture control and shelf stability.

• Water treatment & boiler systems: Sequestration, corrosion inhibition, and pH control in municipal and industrial water-treatment chemistries.

• Detergents & cleaners: Water softening and pH adjustment in powdered and liquid detergent formulations; improves cleaning efficiency and stability.

• Chemical manufacturing: Intermediate for specialty phosphate derivatives, catalysts, and process buffering in fine chemicals production.

• Surface treatment & metal finishing: pH control, cleaning baths, and anti-scalant formulations in electroplating and metal treatment lines.

• Pharmaceuticals & personal care (where appropriate grade): Excipient functions such as buffering and ionic strength control (use only specified pharmaceutical grade and documentation).
  Why it outperforms alternatives:

• Predictable buffering capacity and consistent assay minimize batch-to-batch variation.

• Higher solubility and controlled particle distribution enable faster dissolution and process integration.

• Competitive cost-in-use compared to specialty organophosphates, with broader supplier availability and easier regulatory acceptance for approved grades.

4. Competitive Advantages

• Quality consistency: Produced under controlled conditions with batch COA, specification traceability, and quality management systems to ensure consistent physicochemical properties.

• Supply reliability: Bulk inventory planning and multi-modal logistics support reduce stockout risk for large-scale users.

• Logistics capability: Flexible packaging (bags, FIBCs, flexitanks), consolidated LCL and FCL container loading, and export documentation enable efficient global shipping.

• Price competitiveness: Commodity pricing structure with volume discounts and long-term contract opportunities for industrial buyers.

• Sustainability: Efficient production pathways and packaging optimization reduce waste; supplier can provide declarations for environmental compliance and restricted-substance limits on request.

• Technical support: Dedicated technical datasheets, safety data sheets (SDS), and application guidance available; lab-support and sample evaluation on commercial request.
  Positioning: Procured as a strategic raw material — chosen for predictable performance, supply security, and favorable cost-in-use for high-volume industrial operations.
