Description of key information
No effects up to the limit of water solubility (< 0.05 mg/L; OECD 201).
Key value for chemical safety assessment
Additional information
One study is available investigating the effects of dodecyl oleate (CAS 36078-10-1) to aquatic algae (Hafner, 2012). The study was performed according to OECD 201 (GLP) with the green algae Desmodesmus subspicatus. Five loading rates up to 100 mg/L (nominal) were tested in this study. The loading rates were prepared by siphoning an appropriate amount from the middle after a suitable stirring and settling period (Water Accommodated Fraction). Measured values resulted in concentrations below the Limit of Quantification (< 0.005 mg/L) for all test concentrations. No effects on the growth rate and yield resulted after an exposure of 72 h. Thus a NOErLR (72 h) of ≥ 100 mg/L and an ErL50 (72 h) > 100 mg/L resulted. Thus, it can be concluded that no toxicological effects of dodecyl oleate on aquatic algae are expected 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.
