Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 substance was found to be inherently biodegradable by an average of 35 % over the 28-day exposure. A final conclusion of the biodegradability / persistence of the test substance cannot be drawn yet based on the information available. For these reasons the substance temporarily shall be assessed as "inherently biodegradable, not fulfilling specific criteria.
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable, not fulfilling specific criteria
Additional information
The substance was found to be inherently biodegradable by an average of 35 % over the 28-day exposure. The substance therefore fails to be categorised as "not persistent" acc. to ECHA's "Guidance on information requirements and chemical safety assessment - Chapter R.11: PBT Assessment", as the cut-off criterion is 70% inherent biodegradability within 7 days in the Zahn-Wellens-Test. On the other hand the substance cannot yet finally be categorised as "persistent", as the same guideline requests an inherent biodegradability after 28 days < 20% for substances to be classified as persistent.
A final conclusion of the biodegradability / persistence of the test substance cannot be drawn yet based on the information available. For these reasons the substance temporarily shall be assessed as "inherently biodegradable, not fulfilling specific criteria.
The substance further failed the test on ready 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).
