Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 vapour pressure of hexacos-1-ene at 25˚C is <0.0000889 hPa based on read across from other category members.

Key value for chemical safety assessment

Vapour pressure:
0.009 Pa
at the temperature of:
25 °C

Additional information

Data are available for members of this category with between 6 and 18 carbon atoms. Data are also available for an alpha olefin with a carbon range of C20 - 22. There is a clear trend of decreasing vapour pressure with increasing carbon number. We can therefore conclude that the vapour pressure of hexacos-1-ene is <0.0000889 hPa based on read across from octadec-1-ene (Zwolinski and Wilhoit, 1971).
