Description of key information
NOEC (72h) = 0.0113 mg/L (measured geom. mean) for P. subcapitata (OECD 201)
Key value for chemical safety assessment
Additional information
One experimental study investigating the toxicity of Oleic acid, monoester with oxybis(propandiol) (CAS 49553-76-6) to algae is available (Sloman, 2012). The study was conducted according to OECD 201 under GLP conditions. Pseudokirchneriella subcapitata was exposed to five measured concentrations between 0.00761 and 0.125 mg/L (geom. mean) in a static test for 72h resulting in an EC50 > 0.125 mg/L (geom. mean) and a NOEC = 0.0113 mg/L (geom. mean) based on growth rate.
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.
