Sodium Citrate
Sodium Citrate (CAS #: 68-04-2 / 6132-04-3) is the trisodium salt of citric acid, also known by its Ph. Eur. name Natrii Citras. It is used in cosmetic formulations primarily as a pH adjuster and chelating agent. It works by neutralizing metal ions typically introduced into formulas via water, helping to stabilize the product.

other● Benefits
Sodium Citrate helps maintain the desired pH level of cosmetic products and extends product stability by chelating (neutralizing) metal ions in the formula. These are functional, formulation-support roles rather than direct skin-active benefits.
