Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

The toxicity of alkenes with the same carbon number is expected to be similar, irrespective of the positioning of the double bond. The reason for this is that these alkenes are neutral organic hydrocarbons which act via non-polar narcosis. The acute toxicity observed is due to the uptake of the chemical (proportional to log Kow) and then disruption of the function of biological membranes. Alkenes with the same carbon number have very similar log Kow and therefore would be expected to have similar toxicities. Data are therefore read across between alpha and internal alkenes.
