Description of key information
No effects up to the limit of water solubility (WS < 0.05 mg/L)
Key value for chemical safety assessment
Additional information
One study evaluating the acute toxicity of propane-1,2,3-triyl trisheptanoate (CAS No. 620-67-7) to fish is available (Scholz, 1994). This test was conducted according to EU Method C1, under GLP conditions. Fish (Danio rerio) were exposed to the test substance for 96 hours within a semi-static water regime at a nominal concentration of 10,000 mg/L. After 96 hours exposure, no mortality was observed in either treatment or control groups. Therefore, the LC50 (96 h) was determined to be > 95 mg/L (nominal concentration) and > 64 mg/L (measured concentration). The determination of measured test concentrations was performed by DOC (Dissolved Organic Carbon) analysis, which is more suitable for substances with higher water solubility. The high reported measured concentration (64 mg/L) despite the low water solubility of the substance (< 0.05 mg/L) shows that probably other constituents from the solution have been accounted for as test substance. Nevertheless, since no effects were observed it can be stated that no acute toxicity to fish within the range of the water solubility of propane-1,2,3-triyl trisheptanoate is expected.
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.
