Description of key information
No effects up to the limit of water solubility based on available data (OECD 211).
Key value for chemical safety assessment
Additional information
One GLP Guideline study according to OECD 211 is available for (Z)-octadec-9-enyl oleate (CAS 3687-45-4). The study was performed with the water flea Daphnia magna under semi-static conditions. Due to the very low water solubility (< 0.05 mg/L) a limit test with a Water Accommodated Fraction (WAF) of nominal 100 mg/L was performed. No effects on reproduction and mortality were recorded after 21 d resulting in a NOELR (21 d) of ≥ 100 mg/L. 0% mortality was recorded in the control whereas 5% mortality was observed in the treatment. This mortality is regarded as natural and tolerated by the test guideline. The chemical analysis resulted in concentrations below the analytical detection limit of 0.0423 mg/L reflecting the very low water solubility of the test item. Based on the result it can be concluded that (Z)-octadec-9-enyl oleate will not exhibit chronic effects on aquatic invertebrates up to the limit of water solubility.
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.
