Disodium Hydrogen Phosphate (DSP)

Disodium Hydrogen Phosphate (DSP), also known as Disodium Phosphate, is a multifunctional phosphate salt widely used as a buffering agent, stabilizer, dispersant, and water softener in food processing, detergents, textiles, and various industrial applications. It is commonly supplied in hydrated forms such as Na₂HPO₄·12H₂O and Na₂HPO₄·7H₂O, as well as in anhydrous form for specific processing requirements.

DSP dissolves readily in water, providing reliable alkaline buffering capacity and stable pH control. Its consistent performance and broad application range make it a cost-effective and high-demand phosphate for both food-grade and industrial-grade markets.

· Strong buffering capacity for stable pH control in aqueous systems

· Excellent water solubility with fast and uniform dissolution

· Available in food-grade and industrial-grade specifications

· Effective water softening by binding calcium and magnesium ions

· Functions as stabilizer, dispersant, and processing aid

· High purity and consistent quality suitable for large-scale manufacturing

Customer Focus Points

· Precise pH control requirements → DSP provides stable and reliable buffering performance

· Dual-use demand (food and industrial) → multiple compliant grades available

· Need for good solubility → DSP dissolves easily without residue

· Cost-effective multifunctional ingredient → buffer, softener, stabilizer, dispersant in one product

· Moisture sensitivity → proper dry storage required to prevent efflorescence
