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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

EC number: 939-460-0 | CAS number: 1471311-26-8
Bioaccumulation: aquatic / sediment
Administrative data
Link to relevant study record(s)
Description of key information
The aquatic BCF of a substance is probably lower than 2000 L/kg as the calculated log Kow is higher than 10. The experimentally derived value of Log Kow for the substance is greater than 9.4.
Key value for chemical safety assessment
- BCF (aquatic species):
- 2 000 L/kg ww
Additional information
In accordance with Annex IX column 2 of the REACH Regulation, a study for bioaccumulation does not need to be conducted if the substance has a low potential for bioaccumulation. The experimentally derived Log Pow value for the substance has been identified as > 9.4. QSAR calculations of Log Pow for the components determined that Log Pow >10 for the majority of the components. ECHA Guidance on Information requirements and chemical safety assessment Chapter R11: PBT assessment (page 28) on determination of bioaccumulation potential states: The aquatic BCF of a substance is probably lower than 2000 L/kg if the calculated log Kow is higher than 10. A study is therefore considered scientifically unjustified with regard to the low bioaccumulative potential of the substance.
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.
