Use & Benefits

Dipotassium phosphate is a chelant or a sequestrant. It is actually a type of preservative. When Dipotassium phosphate is added to any formulation, it attracts polyvalent cations such as iron, nickel or copper, which otherwise form complexes with other actives and may degrade the formulation by oxidation. It is also used as a buffering agent to maintain a certain level of an acidic environment in any product. Certain product decomposes when there is a pH change, because of other ingredient or some impurities, the buffering agent lowers the pH to formulation to produce its effect fully. In regulatory status, it comes as GRAS (Generally recognized as safe).
