Description of key information

The study does not need to be conducted because direct and indirect exposure of the soil compartment is unlikely, see column 2 of REACH Annex IX, point 9.4.

Moreover, DD-lactide is rapidly hydrolysed to lactic acid. Lactic acid is therefore the only relevant species in the environment. 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.
