Pentasodium Triphosphate

What Pentasodium Triphosphate is & what it does

Pentasodium Triphosphate is an inorganic sodium phosphate salt that functions primarily as a chelating agent and pH adjuster in cosmetic formulas. By binding trace metal ions it helps keep products stable and can improve the performance of cleansing or emulsified systems. It is typically used at low levels as a formulation aid rather than an active skincare ingredient. It is generally considered safe at the concentrations used in cosmetics.
