Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 log Kow of octacos-1-ene is >8 based on read across from other category members

Key value for chemical safety assessment

Log Kow (Log Pow):
8
at the temperature of:
20 °C

Additional information

Measured data is available for members of this category with 6, 8 and 18 carbon atoms. Data is also available for an alpha olefin with a carbon range of C20-22 (Webb, 2001). There is a clear trend of increasing log Kow with increasing carbon number. We can therefore conclude that the log Kow of octacos-1 -ene is >8. This is supported by the QSAR predicted value of 13.96 and 16.31 (USEPA 2008; Karickhoff et al, 2009).
