Trisodium Phosphate is an inorganic phosphate salt and the tribasic sodium salt of phosphoric acid. It is also known as Trisodium Orthophosphate and Tribasic Sodium Phosphate. The anhydrous compound has CAS Number 7601-54-9, molecular formula Na₃PO₄, and molecular weight 163.94 g/mol.
Trisodium Phosphate is generally supplied as a white to colorless crystalline solid. The anhydrous material is hygroscopic and has good water solubility. PubChem reports water solubility of approximately 121 g/L at 20°C for anhydrous Trisodium Phosphate.
In cosmetic formulation development, Trisodium Phosphate can be evaluated as a buffering, pH-adjusting and chelating ingredient in suitable formulations. The Cosmetic Ingredient Review has included Trisodium Phosphate among the cosmetic ingredients assessed for safety under specified conditions of use.
Trisodium Phosphate is different from Disodium Phosphate and Sodium Phosphate Monobasic because it contains three sodium ions and has different chemical and buffering characteristics.
For formulation development, manufacturers should evaluate concentration, pH, solubility, ionic strength, compatibility with other ingredients, processing conditions, packaging and finished-product stability.
Trisodium Phosphate is the tribasic sodium salt of phosphoric acid. It is commonly identified as Sodium Phosphate Tribasic or Trisodium Orthophosphate.
The anhydrous form has CAS 7601-54-9, formula Na₃PO₄, and molecular weight 163.94 g/mol.
A hydrated form, Trisodium Phosphate Dodecahydrate, is also commercially recognized and has CAS Number 10101-89-0. Because hydration changes the molecular weight and physical properties, the exact grade should be identified in the product specification.
Important technical information includes:
Trisodium Phosphate can be evaluated in suitable cosmetic formulations where buffering, pH adjustment or metal-ion complexation is required.
Potential applications include:
The actual concentration and application should be established according to the selected grade, formulation requirements and applicable cosmetic regulations.
Trisodium Phosphate may be evaluated in suitable cleansing systems because of its alkaline and phosphate characteristics.
Potential applications include:
Formulators should carefully evaluate the final formulation pH and skin compatibility because Trisodium Phosphate is an alkaline phosphate salt.
Trisodium Phosphate can be evaluated in appropriate hair-care systems where pH adjustment or formulation-support functionality is required.
Potential applications include:
Compatibility with surfactants, polymers, conditioning agents and preservatives should be evaluated during formulation development.
Important formulation considerations include:
The anhydrous and hydrated forms should not be treated as identical because their molecular weights and water content differ.
