Pentasodium Triphosphate
A phosphate salt used as a chelator to bind metal ions and as a buffer.
What it does
Pentasodium Triphosphate is a phosphate salt. It binds trace metal ions (chelation), which keeps them from speeding up spoilage or color change, and it can buffer pH, so it is used to support a formula's stability. It is a formulation ingredient rather than a skin active.
