Description of key information

According to REACH Annex IX, point 9.4, short-term toxicity to soil microorganisms can be assessed by the equilibrium-partitioning method if no terrestrial data are available. Lactic acid is practically non-toxic to aquatic organisms. Corrected for the pH effect, no hazard was identified for lactic acid/lactate. This can be safely extrapolated to the terrestrial compartment. Therefore, based on the chemical safety assessment according to Annex I, testing of short-term toxicity to soil microorganisms is not required.
