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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Biodegradation in water: screening tests
Administrative data
Link to relevant study record(s)
Description of key information
A biodegradation study (OECD 301B) with the substance showed 23% degradation. The test substance is therefore considered not readily biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
Pre-solubility tests indicated that the test substance was virtually insoluble in water, therefore the test substance was dissolved in acetone, applied to a filter paper and evaporated to dryness. Pieces of filter paper were included in the medium with inoculum.
The test substance was tested in a CO2 evolution test after being applied to filter paper (10 mg C/L). The filter paper was dispersed in the medium with inoculum for 29 days. The test substance attained 23% degradation and is therefore considered not readily biodegradable (Harlan 2012d).
The analogue substance was reported to be not readily biodegradable in a closed bottle test (Lamberti 2000)
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.
