Description of key information

No toxic effects up to the limit of water solubility (< 0.92 mg/L) for Cyprinus carpio (OECD 203).

Key value for chemical safety assessment

Additional information

One static GLP-study, investigating the short-term toxicity to freshwater fish of Fatty acids, C16-18 (even numbered) and C18-unsatd., branched and linear, di- and triesters with trimethylolpropane (former CAS 85005-23-8), is available. This study (Bogers, 1997) with Cyprinus carpio according to OECD 203 and EU Method C.1 determined a LC50 (96 h) of > 100 mg/L (nominal). No lethal or other visible effects were observed within the tested concentration (100 mg/L nominal) during 96 h of exposure. As test substance drops floating at the surface of the medium, the tested concentration demonstrated a worst case. Due to the low water solubility of the test substance (< 0.92 mg/L), no toxicity was observed in the range of water solubility of the test substance.
