Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
Additional information
C12 -18 AO was readily biodegradable in studies performed to ISO 14593 and OECD TG 301 D. Similar results were obtained for C12 -14 AO in a number of studies performed to OECD TG 301 B or D. In a continuous activated sludge (CAS) test performed using C12 -14 AO, removal of parent amine oxide was > 99.8 % in both units. In a monitoring study, the influent and effluent concentrations of C12 and C14 amine oxide was measured in six municipal sewage treatment plants. The BOD removal was 96-98 %. On the basis of these studies, a removal rate in STP of 98 % is proposed for modelling. In a river water die away study performed using C12 -14 AO the half life of amine oxide was determined to be 3.2 days. In a biodegradation test performed using anaerobic digester sludge the rate constant for mineralization of C12 -14 AO was 1.32/day. These results of these studies are read across to C12 -18 AO.
Based on these studies, performed under both aerobic and anaerobic conditions, it is expected that amine oxides, including C12 -18 AO will be rapidly degraded in the environment, both in the aquatic environment and in soil and sediment.
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.
