Description of key information

No toxic effects up to the limit of water solubility (< 1 mg/L) for Danio rerio (OECD 202).

Key value for chemical safety assessment

Additional information

One short-term study with Daphnia magna 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 48 hour period was conducted according to OECD guideline 202. 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 (EL50 > 100 mg/L; NOELR ≥ 100 mg/L).

Thus, fatty acids, C18-unsatd., dimers, 2-ethylhexyl esters is not harmful to aquatic invertebrates.
