Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Aquatic PNECs were derived using the equation that underlies the PETROTOX model. As the aquatic PNECs are greater than the water solubility of the test substance toxicity is not expected and so soil and sediment PNECs are not calculated.

Conclusion on classification

All the ecotoxicity data for octadec-1 -ene are read across from other category members and are expressed in terms of loading rate rather than exposure concentrations. These data are not suitable for comparison with the classification criteria. Poorly water soluble substances may require a precautionary classification of R53 'May cause long term adverse effects in the aquatic environment' under the DSD and Chronic Category 4 under the CLP Regulations. However, this is not required for octadec-1 -ene as it is readily biodegradable.
