Dipotassium Phosphate is an inorganic phosphate salt and the dipotassium salt of phosphoric acid. It is also known as Dipotassium Hydrogen Phosphate, Dibasic Potassium Phosphate, and Potassium Phosphate Dibasic.
Dipotassium Phosphate has the CAS Number 7758-11-4, molecular formula K₂HPO₄, and molecular weight 174.18 g/mol for the anhydrous form. It is generally supplied as a white crystalline powder or crystals and is readily soluble in water.
In cosmetic formulation development, Dipotassium Phosphate can be evaluated as a buffering agent and pH-adjusting ingredient in suitable aqueous and personal-care formulations. It is commonly used as part of phosphate buffer systems together with a suitable monobasic phosphate salt.
Dipotassium Phosphate should be distinguished from Monopotassium Phosphate, Disodium Phosphate, and Trisodium Phosphate, because these compounds have different chemical compositions, molecular weights and buffering properties.
Dipotassium Phosphate is also available in hydrated forms. Therefore, the exact hydration state should be confirmed before specifying molecular weight, assay calculations and product specifications.
Dipotassium Phosphate is the dibasic potassium salt of phosphoric acid. It is represented chemically by K₂HPO₄ in its anhydrous form.
The anhydrous material has:
Dipotassium Phosphate is water-soluble and can be used in suitable formulation systems requiring phosphate buffering or pH control.
Important technical information includes:
Dipotassium Phosphate can be evaluated as a formulation-support ingredient in suitable cosmetic and personal-care products.
Its primary formulation role is associated with buffering and pH adjustment. It can be incorporated into phosphate buffer systems to help maintain a desired formulation pH.
Potential applications include:
The appropriate concentration should be established according to the formulation requirements, selected grade and applicable cosmetic regulations.
Dipotassium Phosphate can be evaluated in suitable skincare formulations where pH control is required.
Potential applications include:
Formulators should evaluate the final pH, buffer capacity, ionic strength and compatibility with active ingredients, preservatives and other formulation components.
Dipotassium Phosphate can be evaluated in appropriate hair-care formulations as part of a buffering system.
Potential applications include:
Compatibility with surfactants, polymers, conditioning agents and preservatives should be evaluated during formulation development.
Important formulation considerations include:
The hydration state should be confirmed because hydrated material has a different molecular weight from the anhydrous form.
