Description of key information
A NOEC of ≥ 1 mg/L (nominal) was determined in a study with Daphnia magna with the analogue substance 2-ethylhexyl oleate (CAS: 26399-02-0). No effects were observed below the limit of water solubility.
Key value for chemical safety assessment
Additional information
Kuech (1995) investigated the effects of the analogue substance 2-ethylhexyl oleate (CAS: 26399-02-0) to the freshwater invertebrate Daphnia magna. The study was performed according to OECD guideline 202, part 2. Nominal test concentrations applied were 1 and 100 mg/L. For both, measured concentrations were < 0.01 mg/L. Effects to Daphnia magna were only observed after 21 days with 90% mortality in the highest test concentration of 100 mg/L. Since measured concentrations were the same for the 1 and 100 mg/L concentrations effects were considered to be due to contamination of the test substance and the NOEC determined to be ≥ 1 mg/L (nominal). No effects below the limit of water solubility were observed. Based on the results and considering the analogue approach it can be concluded, that the category members of the Long Chain Alcohol Esters produce no long-term effects to aquatic invertebrates.
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.
