What is Sodium Citrate?

Sodium Citrate is the sodium salt of citrate with alkalinizing activity. Upon absorption, sodium citrate dissociates into sodium cations and citrate anions; organic citrate ions are metabolized to bicarbonate ions, resulting in an increase in the plasma bicarbonate concentration, the buffering of excess hydrogen ion, the raising of blood pH, and potentially the reversal of acidosis. 

In addition, increases in free sodium load due to sodium citrate administration may increase intravascular blood volume, facilitating the excretion of bicarbonate compounds and an anti-urolithic effect.

Chemical Properties

White to off-white crystalline powder
Sodium citrate is odorless and has a pleasant, acid taste. Sodium citrate is anhydrous or contains two molecules of water of crystallization
Occurrence Citric acid and its salts occur naturally in many plants and animals.
Uses sodium citrate may be used in cosmetic formulations as an alkalizer and to bind trace metals in solutions (by means of a chelating action). It is the sodium salt of citric acid.
