Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
In a modified Sturm test (OECD 301B) and a MITI test (OECD 301C) degradation rates below 10% were determined. Thus, the substance is regarded as poorly biodegradable.
Further degradation tests were performed according to OECD guideline 308 (water / sediment simulation tests under aerobic and anaerobic conditions).
In these studies the primary degradation from water and sediment goes rapidly (DT50 approx. 8 days under aerobic conditions and DT50 approx. 20 days under anaerobic conditions).
The major degradation pathway of the substance was the incorporation of the degradation produtcs into the organic matter (DT50 main degradation product 40-64 days under aerobic conditions).
However, the mineralization was insignificantly low (approx. 1%). Hence, the substance can be regarded as not readily biodegradable but will be fast eliminated in the environment.
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.
