Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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.
