Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

In a closed bottle test the test item showed 71 % biodegradation after 28 days (14 -d window passed), therefore it was considered to be readily biodegradable.

Key value for chemical safety assessment

Biodegradation in water:
readily biodegradable

Additional information

The test substance in a mineral medium was inoculated with secondary effluent and incubated for 28 d under aerobic conditions in closed bottles (EU method C.4 -E). Based on determination of the content of dissolved oxygen (amount of oxygen taken up by the test chemical), a biodegradation of 71 % was determined after 28 days. Therefore the test substance was considered to be readily biodegradable.
