Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Applicant's summary and conclusion

Validity criteria fulfilled:
yes
Interpretation of results:
other: Partial degradation, but not readily biodegradable
Conclusions:
The substance is not readily biodegradable
Executive summary:

The ready biodegradation has been assessed by the manometric respirometry method using activated sludge with aniline as a positive control. Degradation of the material achieved 43% after 28 days and is not considered readily biodegradable.
