CAS number: 123-76-2
The PBT Assessment for the substance is
based on the criteria set out in the “Guidance on information
requirements and chemical safety assessment, Chapter R.11: PBT/ vPvB
assessment (ECHA, 2014).
The substance is readily biodegradable; it
presents a biodegradation rate > 60 %, meeting the 10-day window in the
28-day test.. Thus, the test substance does not meet the criteria for
persistence and it is not considered to be P or vP.
The uptake of an organic substance is
driven by its hydrophobicity. For organic substances with a Log Kow
value below 4.5 it is assumed that the affinity for the lipids of an
organism is insufficient to exceed the B criterion, i.e. a BCF value of
2000 (based on wet weight of the organism, which refers to fish in most
cases) (Chapter R.11, version 2.0, November 2014). The substance has a
LogKow of - 0.498. Thus the substance is not considered to be B or vB.
Studies on the acute oral toxicity of the
substance showed that it is expected to be toxic after an acute exposure
via the oral route. Its reproductive/developmental toxicity and toxicity
after repeated dose is not yet evaluated since a testing proposal is
submitted for both endpoints. The substance is not classified for
mutagenicity. Based on the available data the substance is not
considered to have Toxic properties.
The substance is not considered as
persistent (P), bioaccumulative (B) nor toxic (T), and it is not
considered as PBT.
