Additional information
One study is available investigating the biodegradation of Isooctadecanoic acid, 1,1'-(2,2-dimethyl-1,3-propanediyl) ester (CAS 109884-54-0). The study was performed according to OECD 301B (GLP) under aerobic conditions using activated sludge from a sewage treatment plant treating predominantly domestic sewage and a test concentration of 26.1 mg/L (Junghans, 2009). A biodegradation of 95% (CO2 evolution) was observed after 28 d. Since the substance reached the pass level for OECD 301B (biodegradation is > 60% after 28 d, meeting the 10-day window) it is considered to be readily biodegradable according to the OECD criteria. All validity criteria of the guideline were met.
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.
