Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water and sediment: simulation tests

Description of key information
In accordance with column 2 of REACH (REGULATION (EC) No 1907/2006) Annex IX, the sediment simulation testing (required in section 9.2.1.4) does not need to be conducted as the substance does not have a high potential for adsorption to sediment and is highly volatile. This is supported by the n-octanol/water partition coefficient information indicating that diethyl ether has a Log Kow <3 (=1.05) as well as by the high Henry Law constant and vapour pressure.
This also holds true for simulation testing on ultimate degradation in surface water (9.2.1.2) and 9.2.3. identification of degradation products.
Additionally, this is supported by the outcome of exposure and risk assessment showing that risks are well controlled based on conservative PNECs using high uncertainty factors. This assessment is in line with Annex XI (3) REACH.

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.
