Additional information

Sodium lactate fully dissociates into Na+ ions and lactate in aqueous environments. The bioaccumulation potential of sodium lactate in the environment can be understood in terms of the bioaccumulation potential of sodium chloride and lactic acid.

Sodium chloride is inorganic and has a high water solubility Sodium and chloride ions are essential constituents of the body of all animals and the concentration of both ions are maintained in the vertebrate body by fractional excretion.

Lactic acid is highly soluble in water, has a low log Kow (-0.72) and is readily biodegradable.

Both sodium chloride and lactic acid will not bioaccumulate, therefore sodium lactate is not expected to bioaccumulate or bioconcentrate.
