Description of key information

No effects up to the limit of water solubility (< 0.05 mg/L; OECD 202).

Key value for chemical safety assessment

Additional information

One GLP Guideline study is available investigating the short-term toxicity of 2-octyldodecyl isooctadecanoate (CAS 93803-87-3) to aquatic invertebrates is available (Bogers, 1998). The study was performed according to OECD 202 with the water flea Daphnia magna. A Water Accommodated Fraction (WAF) of nominal 86 mg/L was prepared and tested under static conditions (limit test). A chemical analysis of the test substance concentrations in the test vessels was not possible since no applicable method could be established due to the very low water solubility to detect test concentrations. No immobilisation was observed after 48 h and therefore an EL50 of > 86 mg/L (nominal) was derived.Based on this result it can be concluded that no toxicological effects on aquatic invertebrates are expected up to the limit of water solubility for2-octyldodecyl isooctadecanoate.
