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.

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.
