Description of key information
No effects up to the limit of water solubility for Crangon crangon (AEP2 guideline, Ministry of Agriculture, Fisheries and Food of the United Kingdom, 1984)
Key value for chemical safety assessment
Additional information
One experimental study investigating the short-term toxicity of isopropyl oleate (CAS No. 112-11-8) to aquatic invertebrates is available. Since this study is conducted with a marine organism, the assessment is supported by a freshwater study conducted with the structurally most similar category member, for which freshwater data is available, isopropyl palmitate (CAS No. 142-91-6). This read across approach is in accordance with Regulation (EC) No 1907/2006, Annex XI, 1.5. Grouping of substance and read across approach. Further justification is given within the endpoint summary 6.1 and within the category justification section 13. In this case of read-across, the best suited (highest degree of structural similarity, nearest physico-chemical properties) read-across substance was entered into IUCLID. Nevertheless, as can be seen in the data matrix of the category justification in Section 13, all reliable data in the category support the hazard assessment for this endpoint, by showing a consistent pattern of results.
The key study conducted with isopropyl oleate (CAS No. 112-11-8) was performed according to the guideline AEP2 issued by the Ministry of Agriculture, Fisheries and Food of the United Kingdom (1984) (Clitherow, 1991). The marine test organism Crangon crangon was exposed to the test substance in a static system for 48 hours, at nominal test concentrations of 850, 1530, 2640, 4760 and 8500 mg/L. No mortality was observed at any of the test concentrations.
The supporting study with isopropyl palmitate (CAS No. 142-91-6) was performed according to EU Method C.2 and GLP (Kirch, 1998). The test organism Daphnia magna was exposed to the test substance in a static system for 48 hours, at nominal test concentrations of 1000 and 3000 mg/L (measured initial concentrations 0.72 and 1.68 mg/L). No mortalities were observed at any of the test concentrations.
Thus, based on theabove mentioned results, and due to the structural and profile similarities of the two substances, as are explained with in the overall endpoint summary 6.1 it can be concluded that no toxicological short-term effects on aquatic invertebrates are expected up tothe limit ofwater solubility for isopropyl oleate (CAS No. 112-11-8).
