Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Biodegradation in water: screening tests
In a valid follow-up study applying the OECD method 310 (Ready Biodegradability - CO2 in Sealed Vessels, Headspace Test), biodegradation of 60 % was reached after 23 d within a 12-days window, hence just failing the 10-days window (Fiebig/NOACK 2013) (see Chapter 4.1.2.1.3.). GC-analysis demonstrated >99% elimination of the original substance after 16 days.
A MITI II test (OECD 302 B, 28 d) apparently suggested only poor biodegradation with a low BOD of about 12 %. However, GC-analysis suggested significant primary structural changes under the test conditions (removal of the pristine test substance of about 93 %). As pointed out above, this study is considered unreliable and, therefore, has been disregarded for further assessment.
Biodegradation in water and sediment: simulation tests
No data available. Study has been waived based on favourable results in a ready-test.
Biodegradation in soil
No data available
Mode of degradation in actual use
No data available (not required for REACH)
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). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
