Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Not readily biodegradable: 1% (ThOD) in 28 days (OECD 301 D)
Inherently biodegradable: 84% (ThOD) in 28 days (OECD 302 C)
Key value for chemical safety assessment
- Biodegradation in water:
- inherently biodegradable
Additional information
Ready biodegradation of the reaction mass was investigated in one GLP-study according to OECD guideline 301 D (Richter, 2012a). Domestic, non-adapted secondary effluent was used as inoculum. The reaction mass attained 1% degradation after 28 days of incubation. Hence, the substance is not readily biodegradable in terms of the strict OECD criteria.
A further GLP-study investigating the inherent biodegradability of the reaction mass is available (Richter, 2012b). The test was carried out according to OECD guideline 302 C and domestic activated sludge was used as inoculum. After a lag phase of 12 days, the pass level of 70% degradation was reached at day 22. Degradation finally reached 84% after 28 days. This result indicates, that the substance can be ultimately biodegraded under environmental conditions.
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.
