Potassium Phosphate · Dipotassium Phosphate
A phosphate buffer salt that holds a formula at a steady, skin-suitable pH.
What it does
Potassium phosphate is a phosphate buffer salt, usually paired with a more acidic phosphate, that resists pH swings and holds a formula near its target pH. A stable pH protects ingredient performance and keeps a product comfortable on skin. It is a pH-control ingredient rather than a skin active.
