Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In OECD Guideline 301B, C, and D studies, the test substance was determined to be not Readily Biodegradable. In a test for inherent biodegradation (OECD 302C), however, the test substance was determined to be inherently biodegradable.

No rate constant for elimination in a sewage treatment plant can be provided, however. The results of inherent biodegradation tests can be used for determining a rate constant only if a level of 70% degradation is reached within 14 days in the Modified MITI Test (II).
