Description of key information
EC10 (3h) = 720 mg/L (nominal) for respiration rate of non-adapted domestic activated sludge (OECD 209)
Key value for chemical safety assessment
- EC10 or NOEC for microorganisms:
- 720 mg/L
Additional information
One study investigating the toxicity of Fatty acids, C8-18 and C18-unsatd., reaction products with diethanolamine and propylene oxide (CAS 1000817-22-0) is available. The study was performed according to OECD guideline 209 and GLP using non-adapted domestic activated sludge as inoculum (BASF 2015). The test substance was directly added to the test vessels. Nominal concentrations between 62.5 and 1000 mg/L were tested. The 3h-EC50 value is determined to be > 1000 mg/L and the 3h-EC10 value is determined to be 720 mg/L.
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.
