Sodium Polyphosphate

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.

What does Sodium Polyphosphate do in skincare?

Sodium Polyphosphate is used mainly as a chelating and sequestering agent. It helps bind trace metal ions, which can support a product's stability over time. It can also assist with buffering the formula's environment.

Is Sodium Polyphosphate natural or synthetic?

Sodium Polyphosphate is a synthetic inorganic salt produced for industrial and cosmetic use. It is manufactured rather than sourced from a plant or animal. It appears in formulas at low levels for its stabilizing role.

Is Sodium Polyphosphate safe?

Sodium Polyphosphate is used in cosmetics as a chelating and buffering agent at low concentrations. Ingredients of this type are typically present in small amounts for formula stability. If you have reactive skin, patch testing a new product is a reasonable step.
