Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

The ready biodegradability of the test substance was assessed  in a CO2 Evolution Test following OECD guideline No. 301B (1993). The  biodegradation after 31 days was 0% (CO2 related to ThCO2). The DOC elimination degree after 31 days was 15%. Further, the biodegradability of the test substance was assessed in a Manometric Respirometry Test following OECD Guideline 301 F (1993). Elimination degree after 33 days was as "BOD of ThOD"14% and as "BOD of COD" 10%. Thus, the test substance is in both tests was poorly biodegradable (BASF, 1995) .
