Disodium Phosphate is a white, crystalline powder that is highly soluble in water and serves multiple functions in cosmetic formulations. It acts as a buffering agent, helping to maintain the pH stability of formulations. It can also function as a chelating agent, assisting in the removal of metal ions that could negatively impact the stability or appearance of the product. Additionally, Disodium Phosphate can be used as a viscosity-modifying agent, enhancing the texture and thickness of certain cosmetic formulations. The chemical formula of Disodium Phosphate is Na2HPO4.
Origin
Disodium Phosphate is typically produced through the reaction of phosphoric acid with sodium hydroxide or sodium carbonate. The reaction results in the formation of Disodium Phosphate, which is then further purified and processed to obtain the desired purity and physical characteristics for use in cosmetics.
Safety profile
Disodium Phosphate is recognized as safe for use in cosmetics and personal care as it is non toxic and has minimal to zero side effects. It is also gluten-free and is safe for individuals with gluten sensitivities or celiac disease. However, a patch test is a must before trying any new product containing Disodium Phosphate.
