Description of key information

No toxic effects up to the limit of water solubility (< 1 mg/L) for Danio rerio (OECD 203), read-across.

Key value for chemical safety assessment

Additional information

One short-term study with the freshwater fish Pimephales promelas (Fathead minnow) in a static system is available (Swarbrick and Smyth, 2005) for Fatty acids, C18-unsatd., dimers, 2-ethylhexyl esters (CAS No. 68334-05-4). The study over a 96 hour period was conducted according to OECD guideline 203. As the test substance has a low water solubility (< 1 mg/L) water accommodated fractions (WAFs) with a loading rate of 100 mg/L were used during this test. No effect up to the limit of the water solubility of the tested substances was observed (LL50 > 100 mg/L; NOELR ≥ 100 mg/L).
