Frequently Asked Questions

Q: Disodium Phosphate Properties?

A: Disodium hydrogen phosphate (Na2HPO4) is a sodium salt of phosphoric acid. DSP is a white powder that is highly hygroscopic and water soluble. Sodium phosphate dibasic is therefore used commercially as an anti-caking additive in powdered products. DSP is also known as disodium hydrogen orthophosphate, sodium hydrogen phosphate or sodium phosphate dibasic. Disodium phosphate is commercially available in both the hydrated and anhydrous forms. PH of disodium hydrogen phosphate water solution is between 8.0 and 11.0.



Q: Disodium Phosphate Application?
Disodium phosphate is used in Cream of Wheat to quicken cook time, as described on the ingredients panel of the product package.Disodium phosphate is used in conjunction with trisodium phosphate in many steam-boiler applications. It supplies the inventory of free phosphates to retard calcium scale formation.Monobasic sodium phosphate and dibasic sodium phosphate is used as a saline laxative to treat constipation or to clean the bowel before a colonoscopy.
