Description of key information

No toxic effects up to the limit of water solubility for Salmo gairdneri (OECD 203)

Key value for chemical safety assessment

Additional information

One study, investigating the short-term toxicity to freshwater fish, was available for Fatty acids, C5-10, esters with pentaerythritol (CAS-No. 68424-31-7). This semi-static study (Combert and Caunter, 1991) with Salmo gairdneri equivalent or similar to OECD 203 determined LC50 (96h) > 1000 mg/L (nominal). No mortality was observed within the tested concentration (1000 mg/L nominal) during 96h exposure. As the test material did not dissolved completely in the dilution water, the tested concentration demonstrated a worst case. Due to the low water solubility of the test substance (< 1 mg/l), no toxicity was observed in the range of water solubility of the test substance. Therefore, the substance is not harmful to fish.
