What Sodium Polyphosphate is & what it does
Sodium Polyphosphate is a synthetic inorganic salt used in cosmetics primarily as a chelating agent and buffering or sequestering agent. In skincare and sunscreen formulas it helps bind trace metal ions, which can support product stability over time. It can also play a role in adjusting the texture or pH environment of a formula.
