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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No simulation tests on the biodegradation of the test substance in soil are available.
Key value for chemical safety assessment
Additional information
No data on the biodegradation of the test substance in simulation tests are available. In an enhanced biodegradation study according to OECD 310, the test substance was degraded from 36% after 25 days up to 54% after a test duration of 60 days (Laus 11012603G606, 2011). The test substance is a highly branched UVCB. Due to their molecular structure, the molecules of this UVCB are likely to be less accessible than compounds that possess linear molecular structures. This steric obstruction could result in a decelerated biodegradation of the test substance.
Since the results from simulation test in water, sediment and soil are not considered to reveal any relevant additional findings, no corresponding studies will be conducted.
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.
