Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The ready biodegradability of the test substance was assessed according to OECD Test Guideline 301 F using a Manometric Respirometry method. The test substance undergoes 10 % biodegradation after 28 days under the conditions of the test.
The inherent biodegradability of the test substance was assessed according to OECD Test Guideline 302 C using a modified MITI method. The test substance undergoes 8 % biodegradation after 28 days (7% after 55 days) under the conditions of the test.
Key value for chemical safety assessment
- Biodegradation in water:
- under test conditions no biodegradation observed
Additional information
The ready biodegradability of the test substance was assessed according to OECD Test Guideline 301 F using a Manometric Respirometry method. The test substance did not inhibit the intrinsic respiration of the inoculums at the test concentration and was therefore considered to be non-toxic to the inoculum at the test concentration. The test substance underwent 10 % biodegradation after 28 days under the conditions of the test. The test substance should be regarded as not readily biodegradable according to this test.
The inherent biodegradability of the test substance was assessed according to OECD Test Guideline 302 C using a modified MITI method. At the test concentration, the test substance did not significantly inhibit the intrinsic respiration of the inoculum.
The test substance undergoes 8 % biodegradation after 28 days (7% after 55 days) under the conditions of the test. Therefore the test substance should be regarded as not inherently biodegradable according to the test. Biodegradation is considered to have started when it exceeds the 10% level. Thus it is concluded that under the above test conditions no biodegradation was observed.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.
