Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Due to the use in dedicated equipment as intermediate, it is not expected that MDA is capable to enter the foodchain. The PNEC oral was derived as a theoretical exercise.

Conclusion on classification

According to regulation 1272/208/EC, MDA is classified as:

H411: toxic to aquatic life with long lasting effects.

According to 67/548/EC, MDA is classified as:

R51/53: toxic to aquatic organisms, may cause long-term adverse effects in the aquatic environment.

Due to the data in this dossier the substances needs to be classified more stricter (H400/H410 accroding to 1272/208/EC and R50/53 according to 67/548/EC, respectively.).
