Description of key information

No acute toxicity effects up to the limit of water solubility.

Key value for chemical safety assessment

Additional information

In general, all LC/LL50(96h) values derived with different fish species for various substances in the SCAE C2 -C8 category were above the limit of water solubility. No mortalities or sublethal effects were observed at any concentration.

No studies are available for Fatty acids, C16-18, 2-ethylhexyl ester on short-term toxicity to fish.

In the selected read-across study with Fatty acids, C16-18 and C18-unsatd., 2-ethylhexyl esters (CAS 85049-37-2) the acute toxicity to Danio rerio was tested according to OECD 203 with nominal concentrations of 1000, 3000 and 10000 mg/L. The test substance was directly added into the test medium and tested as an emulsion. No mortality was observed up to the highest test concentration and an LC50(96h) > 10000 mg/L could be stated (Richterich 2001).

In another read-across from Fatty acids, C8-16, 2-ethylhexyl esters (CAS 135800-37-2), the marine species Scopthalmus maximus was tested with a WAF, resulting in a nominal LL50(96h) value > 5600 mg/L (Van der Kerken 2002).
