Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Considering the calculated Bioaccumulation Estimates (CAESAR model) of BCF = 378 L/kg wet-wt, the readily biodegradability, which makes exposure of the aquatic compartment unlikely, and the low toxicity to fish, a bioaccumulation study in fish would most likely not contribute to the assessment of the substance. Therefore, the respective vertebrate study is considered to be scientifically not justified.
Key value for chemical safety assessment
- BCF (aquatic species):
- 378 L/kg ww
Additional information
Bioaccumulation in fish has been calculated the validated CAESAR model (see http://www.caesar-project.eu/). A BCF of 378 L/kg wet-wt has been determined. As the registered substance falls within the applicability domain of the model, the result is considered reliable and valid. Considering this BCF, the readily biodegradability, which makes exposure of the aquatic compartment unlikely, and the low toxicity to fish, a bioaccumulation study in fish would most likely not contribute to the assessment of the substance. Therefore, the respective vertebrate study is considered to be scientifically not justified.
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.
