Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
In accordance with Column 2 of REACH Annex X, the long-term toxicity testing on sediment dwelling organisms (section 9.5.1) is not necessary. The chemical safety assessment did not indicate the need to investigate further the effects of the substance and/or degradation products on sediment organisms. DMT[EHTG] is considered to rapidly degrade in the environment based on the results of the biodegradability study. The Log Koc and Log Kow values equal 5.19 and 8.5, respectively. It is likely that DMT[EHTG] will partition into the sediment. However, the potential for long residence times in the sediment are low due to its ready biodegradability and therefore chronic exposures to sediment dwelling organisms are unlikely. As an alternative to the sediment organism chronic toxicity test, the PNEC sediment was estimated based on the equilibrium partitioning method.

Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
