Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 Koc value was calculated using EPIWIN 4.0. The resulting value of 0.008 L/kg indicates that B-TEGME would not adsorb to soils,or sediments should these environmental compartments be exposed to it.
Key value for chemical safety assessment
- Koc at 20 °C:
- 0.008
Additional information
The QSAR tool EPIWIN 4.0 was applied to calculate a Koc value, based on its Log Kow of -4.37 (EPINWIN 4.0). The resulting Koc estimate of 0.008 L/kg indicates that B-TEGME would not adsorb to soils or sediments.
It should be mentioned that, in accordance with EC 1907/2006, Annex VIII, point 9.3.1, column 2, assessment of the adsorption/desorption behavior of B-TEGME is not required due to its ready biodegradability and its low octanol-water partition coefficient, indicating that it has a low potential to adsorb to soils/sediments. Hence environmental exposure assessment is not being done.
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.
