Sodium Citrate
Sodium Citrate
A pH buffer and mild chelator — the salt of citric acid that keeps a formula's pH steady over time.
What it does
Sodium citrate buffers pH, meaning it resists swings that would otherwise destabilize a product or make actives less effective. It is frequently used together with citric acid to lock a formula into its target range, and it has mild metal-binding (chelating) ability that supports stability. It is a behind-the-scenes formulation aid, not an active.
