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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Based on the low measured log Pow value (log Pow= 2.4, Evonik Industries, 2010) for EGDMA a bioaccumulation rate of 21.9 was estimated according to the formula of Veith et al. 1979 (Guidance R.7C). In the OECD SIDS program a low bioaccumulation potential with a BCF of 3 has been estimated with EPIWIN, 2009, program BCFBAF.
Further studies do not need to be conducted as the substance is readily biodegradable (experimental result please see chapter 5.2.1. biodegradation screening test according to EEC Dir. 84/449, published in: Official Journal of the European Communities, No. L251/188, Closed Bottle Test).
Key value for chemical safety assessment
- BCF (aquatic species):
- 21.9 dimensionless
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.
