Key value for chemical safety assessment
Additional information
One study is available investigating the biodegradation of 2,2-bis(hydroxymethyl)propane-1,3-diyl didocosanoate (CAS 68258-72-0; Simon, 2016). The study was performed according to OECD 301F (GLP) under aerobic conditions using activated sludge from a sewage treatment plant treating predominantly domestic sewage. Two test substance concentrations of 32 and 100 mg/L, corresponding to 92 and 287 mg ThOD/L, respectively were used for testing. A biodegradation rate of 25.6 - 30.2% (O2 consumption) was observed after 28 d. Since the substance did not reach the pass level for OECD 301F (biodegradation is > 60% after 28 d, 10-day window fulfilled) the substance is not readily biodegradable according to the OECD criteria.
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.
