Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 test substance is not supposed to be directly applied to soil and indirect exposure via sewage sludge transfer is unlikely since the substance is readily biodegradable.  For a substance, and its degradation product DMH, being considered as readily biodegradable it can be assumed that it will degrade in the STP process and as a consequence a transfer to the soil compartment is not expected. Therefore no tests on terrestrial organisms are provided

Key value for chemical safety assessment

Additional information

In Annex IX of Regulation (EC) No 1907/2006, it is laid down that short-term toxicity to terrestrial organisms shall be proposed by the registrant if the chemical safety assessment indicates the need to investigate further the effects of the substance and/or relevant degradation products on terrestrial organisms. Column 2 of Annex IX states that studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.

 

It can be concluded that short-term toxicity testing of terrestrial organisms is not required based on the unlikely exposure of soil organisms to the DMDMH product or its degradation product (DMH). Based on the unlikely direct exposure to soil organisms and rapid biodegradability in the environment.
