Additional information
Aquatic PNECs were derived using the equation that underlies the PETROTOX model. As the aquatic PNEC 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 C20-24 alpha olefin is expressed in terms of loading rate rather than exposure concentrations. This data is 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 C20-24 alpha olefins as they are readily biodegradable.
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.
