EC number: 220-020-5
CAS number: 2605-79-0
Screening level data, in which the substance was tested according to
OECD 301B are available for C10 AO. The results of this study show that
the substance is ready biodegradable. Similar results were obtained in
studies performed using C12-14 AO. Based on these studies it is
concluded that amine oxides, including C10 AO, are readily
No simulation tests are available for C10 AO, however a number of
studies have been performed with C12/14 AO or C12 AO alone. The findings
in these studies are considered to be relevant to C10 AO as the
substances have similar physico-chemical properties and are both readily
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 amine oxide was 1.32/day.
Based on these studies, performed under both aerobic and anaerobic
conditions, it is concluded that amine oxides, including C10 AO will be
rapidly degraded in the environment, both in the aquatic environment and
in soil and sediment.
