About this ingredient

Pentasodium triphosphate is an inorganic salt and chelating agent used in cosmetics and personal care products. It functions primarily as a water softener and chelating agent, binding to metal ions that could otherwise cause product instability or discoloration. It also serves as a buffering agent to maintain optimal pH levels in formulations.
