What is Di Sodium Phosphate Anhydrous?
Di Sodium Phosphate Anhydrous (DSP), chemically known as Disodium Hydrogen Phosphate, is a moderately alkaline phosphate salt valued for its buffering, emulsifying, and water-softening properties. Unlike Tri Sodium Phosphate, DSP has only two of its three available hydrogen ions replaced by sodium, giving it a milder alkalinity that makes it particularly suited to food applications requiring precise, moderate pH buffering rather than the strong alkalinity of TSP.
Polychem Industries supplies Di Sodium Phosphate Anhydrous in food grade and industrial grade to processed cheese manufacturers, beverage companies, detergent producers, and water treatment facilities across India and internationally. Its moderate alkalinity and effective buffering capacity make it a valuable functional ingredient across food processing applications requiring precise pH control, while also serving important roles in detergent and water treatment formulations.

| Industrial Grade | White crystalline powder | 98%+ | Industrial | Detergents, water treatment, textile processing, ceramics |
Applications & Uses
Processed Cheese & Dairy
Widely used as an emulsifying salt in processed cheese manufacturing, helping create smooth, uniform texture by emulsifying milk fat and stabilising the casein protein structure during the cheese processing operation.
Beverages & Buffering
Used as a buffering agent in certain beverages, particularly in combination with citric acid or other food acids, to maintain stable pH and prevent flavour or stability issues during storage.
Canned Meat & Seafood
Used in canned meat and seafood products as a pH buffer and water-binding agent, contributing to product texture and stability while helping maintain quality during processing and extended shelf storage.
Egg Products
Used in liquid and frozen egg product formulations as a buffering agent, helping maintain stable pH and improve the functional properties of processed egg products used in food manufacturing.
Detergents & Cleaning Products
Industrial Grade DSP is used as a builder in certain detergent formulations, providing moderate alkalinity and water-softening capability that complements other detergent components.
Water Treatment & Industrial Processing
Used in industrial water treatment applications and various industrial processes requiring its specific buffering and sequestering chemistry, including certain textile processing and ceramic manufacturing applications.
