Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A study was conducted to assess the ready biodegradability of the test substance according to EU Method C.4-D (which is in most parts equivalent to OECD Guideline 301 F), in compliance with GLP. Activated sludge was inoculated with100 mg/L of the test substance (in triplicate) in a closed flask at a constant temperature (22±2°C) for 28 d. Degradation was assessed by the determination of Biochemical Oxygen Demand (BOD) on Days 4, 6, 8, 12, 14, 18, 20, 22, 26 and 28. A toxicity test and a control solution containing the reference substance benzoic acid, sodium salt (100 mg/L) together with inoculum were used for validation purposes. The test substance degraded 0% by Day 28. No toxicity of the test substance was observed in the toxicity control. The reference compound showed 88% degradation at Day 14.Hence, under the study conditions, the test substance was considered to be ‘not readily biodegradable’.
Additional information
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.
