Description of key information
No toxic effects to invertebrates up to the limit of water solubility (WS: < 0.05 mg/L; OECD 202).
Key value for chemical safety assessment
Additional information
Two studies investigating the toxicity of fatty acids C5-10 esters with dipentaerythritol (CAS 70983-72-1) to aquatic invertebrates are available. In the first study the short-term toxicity to aquatic invertebrates was investigated according to OECD 202 using Daphnia magna as test organism under semi-static conditions. A nominal test concentration of 1060 mg/L (prepared as WAF) was tested. Analytical monitoring was not performed. No immobilisation was observed in the treatment throughout the test period of 48 h. Hence, the 48 h-EL50 is determined to be > 1060 mg/L.
The second study was investigated according to ISO 634115 using Daphnia magna as test organism under static conditions. Nominal concentrations of 10, 18, 32, 56 and 100 mg/L (prepared as WAF) were tested. Analytical monitoring was not performed. After 48 h an EL50 of 78 mg/L determined. Due to the fact that a test substance film was observed and Daphnids trapped at the surface were observed after 24 h at 100 mg/L the test has got a reliability of 3.
It can therefore be concluded that the test substance will not exhibit short-term effects to aquatic invertebrates up to the limit of water solubility.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
