Product usage:
In foods,Disodium Phosphate is used to adjust pH. Its presence prevents coagulation in the preparation of condensed milk. Similarly, Disodium Phosphate is used as an anti-caking additive in powdered products. Disodium Phosphate 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 retards calcium scale formation. Disodium Phosphate is also found in some detergents and cleaning agents.
