Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption coefficient (Koc) of substance was determined in a HPLC screening test according to OECD Guideline 121 and under GLP conditions. Under the conditions of the test 4 peaks were seen, showing Kocs in the range of 6020 to 27300 or log Kocs of 3.78 to 4.44. The first two peaks resulted in 80% coverage of the area and therefore this average was chosen for deriving the Koc, resulting in a value of 6760 and log Koc is then 3.83.
Key value for chemical safety assessment
- Koc at 20 °C:
- 6 760
Additional information
The Log Koc presented as key value is further supported by the QSAR for predominantly hydrophobics in EUSES, which resulted in a value of log Koc of 3.57.
[LogKoc: 3.83]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
