EC number: 203-041-4
CAS number: 102-60-3
Phototransformation in air
Estimated half-lives for the structural analogue substance CAS 25214 -63
-5 range from 1.1 to 3.1 hours.
Ether bondage are stable and do not hydrolyse to a significant extent at
environmental relevant condition. This has been confirmed in an OECD 111
study performed with an analogue substance (CAS 25214 -63 -5) in which
the substance was stable at pH 4, 7, 9 at 50 degrees Celsius during 120
hours (Currenta, 2009).
Studies on the biodegradation of the substance are not available. The
presented data refer to a structural analogue of the substance.
In an OECD 301F (manometric ready biodegradability) study on
Ethyleneamine, propoxylated, 9% mineralisation after 28 days was
observed based on oxygen consumption (Bayer, 1993). The substance
exhibited inherent (primary) biodegradability in OECD 302/302B, EU
C.4.D/C.9; mineralisation was ranging from 20 -36% after 28 days based
on DOC removal (Bayer AG, 2002).
The screening tests on the structural analogue indicate that the
substance exhibits inherent (primary) biodegradability, and is therefore
not expected to persist indefinitely in the environment, comparable
degradation rates are exptected for CAS 102-60-3
With a log Kow ≤3, the substance can be considered to have a low
potential for bioaccumulation.
In accordance with Column 2 of REACH Annex IX, the study does not need
to be conducted as the substance can be expected to have a low potential
for sorption (log Kow ≤3). The estimated Koc values for structural
analogues of Ethyleneamine, +4PO range from 4.1 to 116 L/kg for the
lowest (least sorptive) and highest (most sorptive) molecular weight
homologues. The substance can be regarded as having
low affinity for adsorption to soils and activated sludge biosolids.
