Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 partition coefficient of the test substance is calculated to 9.0 at 25°C.

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

Because of the expected very high value of the partition coefficient Pow of the test substance is an experimental determination only with great costs and increased uncertainty possible, so that the proven contribution method of Rekker (R.F.REKKER, The hydrophobic fragmental constant, Elsevier, Amsterdam, 1977, Appendix Page 350 - 355), was used to calculate the partition coefficient.

The value from this calculation was chosen as key value.
