Key value for chemical safety assessment

Additional information

One study is available on the short-term toxicity of Fatty acids, C16-18, butyl esters (CAS No. 85408-76-0) to aquatic invertebrates.

The key study with Fatty acids, C16-18, Bu esters (CAS No. 85408-76-0) was performed as a limit test according to EU Method C.2 and GLP (Wierich, 1998). The test organism Daphnia magna was exposed to the test organism in a static system for 48 hours, at the nominal test concentration of 100 mg/L, prepared as water accommodated fractions (WAF). No immobilisation was observed at any treatment, and an EC50 of > 100 mg/L was reported.
