Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Alkenes C24 - 28 do not contain any hydrolysable functional groups, so will not undergo hydrolysis. A biodgradation screening study is available with alkenes C24 - 28 which did not demonstrate ready biodegradability. A study with alpha olefins C26 - 28 also did not demonstrate ready biodegradability.

Log BCFs have been calculated on the basis of the calculated log Kow using a QSAR that is appropriate for icosene and docosene. These values have been read across to alkenes C24-28. The calculated log BCFs are 1.6 - 2.1. This indicates that alkenes C24-28 is not expected to pose a risk of bioaccumulation or secondary poisoning. A log Koc of >6.56 has also been read across from hexadecene.
