Description of key information
EC10(3h) > 1000 mg/L (nominal) for respiration inhibition of activated sludge (OECED 209)
Key value for chemical safety assessment
Additional information
One study investigating the toxicity of Glycerides, castor-oil mono-, di- and tri- (CAS 91744-27-3) to aquatic microorganisms is available. The study was performed according to GLP and OECD guideline 209 using non-adapted activated sludge from a predominantly municipal STP as test organism (BASF 2017). After an incubation time of 3 h no respiration inhibition were observed in any treatment. Thus, the 3h-EC10 value is determined to be > 1000 mg/L based on nominal concentrations.
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.
