Description of key information
EL50 (21d, immobilisation) > 100 mg/L (nominal) (Daphnia magna, OECD 211)
EL50 (21d, reproduction) > 100 mg/L (nominal) (Daphnia magna, OECD 211)
NOELR (21d, immobilisation) = 100 mg/L (nominal) (Daphnia magna, OECD 211)
NOELR (21d, reproduction) = 100 mg/L (nominal) (Daphnia magna, OECD 211)
No effects up to the limit of the water solubility of the substance.
Key value for chemical safety assessment
Additional information
A GLP guideline study conducted according to OECD 211 on the chronic toxicity of Fatty acids, C18-unsatd., dimers, di-Me esters, hydrogenated (CAS 147853-32-5) is available (Parr, 2013). The study was performed as a semi-static test exposing Daphnia magna for 21 days to five loading rates of the test item prepared as water accommodated fractions (WAFs), i.e. 1.0, 3.2, 10, 32, and 100 mg/L, due to the poor solubility of the test material. No effects were observed in the treatment, thus the EL50 and the NOELR values for immobilisation and reproduction were determined to be > 100 mg/L (nominal) and 100 mg/L (nominal), respectively.
In conclusion, chronic ecotoxicological effects on aquatic invertebrates are not expected up to the limit of water solubility (< 0.1 mg/L) for Fatty acids, C18-unsatd., dimers, di-Me esters, hydrogenated (CAS 147853-32-5).
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
