Disodium Phosphate (DSP) Description

Sodium phosphate dibasic, is the inorganic compound with the formula Na2HPO4. It is one of several sodium phosphates. The salt is known in anhydrous form as well as forms with 2, 7, 8, and 12 hydrates. All are water-soluble white powders; the anhydrous salt being hygroscopic.

Disodium Phosphate (DSP) Properties

White powder in appearance. Easy deliquescence. soluble in water, and the water solution is a weak alkaline base, insoluble in alcohol.

Disodium Phosphate (DSP) Application

Used as a quality improver, an emulsifier, a nutrition enhancer, a fermentation aid and a binder in the food industry.

Disodium phosphate (DSP) is used in conjunction with trisodium phosphate in foods and water softening treatment. In foods, it is used to adjust pH. Its presence prevents coagulation in the preparation of condensed milk. Similarly, Disodium phosphate (DSP) is used as an anti-caking additive in powdered products.

It is used in desserts and puddings, e.g. Cream of Wheat to quicken cook time, and Jell-O Instant Pudding for thickening. In water treatment, Disodium phosphate (DSP) retards calcium scale formation. It is also found in some detergents and cleaning agents.

Packaging and Storage

25kg/50lb kraft paper bag, jumbo bag. Store in a cool, dry, well-ventilated area away from toxic and hazardous chemicals.
