(1) Disodium Phosphate Dodecahydrate is used as a quality improver, an emulsifier, a nutrition enhancer, a fermentation aid and a binder in the food industry.
 
(2) Disodium Phosphate Dodecahydrate is used in conjunction with trisodium phosphate in foods and water softening treatment. In foods, Disodium Phosphate Dodecahydrate is used to adjust pH. Its presence prevents coagulation in the preparation of condensed milk. Similarly, Disodium Phosphate Dodecahydrate is used as an anti-caking additive in powdered products.
 
(3) Disodium Phosphate Dodecahydrate 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 Dodecahydrate retards calcium scale formation. Disodium Phosphate Dodecahydrate is also found in some detergents and cleaning agents.
