Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 PETROTOX model and the soil and sediment PNECs were calculated using the equilibrium partitioning method.
Conclusion on classification
The available aquatic ecotoxicity data are presented in section 7.1 of the CSR. These data result in the following classifications:
Carbon number |
C6 |
C8 |
C10 |
C12 |
C14 |
DSD C&L |
R51/53 |
R50/53 |
R50/53 |
Not classified |
Not classified |
CLP C&L |
Chronic 2 |
Acute and chronic 1 |
Acute and chronic 1 |
Not classified |
Not classified |
The carbon number range of alkenes C6 - 8 covers a cut off between different classifications. A UVCB that covers this carbon number range may require a differing classifications, dependant on the proportion of the differing carbon lengths. To cover this eventuality, it is decided to adopt a precautionary attitude (in the absence of data on the specific substance) and assign the classification of "R50/R53 very toxic to aquatic organisms and may cause long term adverse effects in the aquatic environment" under the DSD Directive and "Acute and Chronic Category 1" under the EU CLP Regulations.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
