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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Ready Biodegradability (CO2 Evolution Test, OECD Guideline 301 B): not readily biodegradable but inherently biodegradable.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
The test substance was not readily biodegradable. The biodegradation was 54 % within 28 days and 31 % within the 10d window.
The test substance is assumed to be inherently biodegradable, as it just missed the threshold of 60 % degradation within 28 days. The ECHA Guidance on Data Requirement and CSA, Part 7b says: "When results of ready biodegradability tests indicate that the pass level criterion is almost fulfilled (i.e. ThOD or DOC slightly below 60% or 70% respectively) such results can be used to prove inherent biodegradability."
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.
