With respect to aquatic bioaccumulation it can be concluded that the
substance has limited bioaccumulation potential based on the measured
log Kow values (3.3 - 3.6). This screening value is considered to be
reliable and is under the threshold value for aquatic organisms : log
Kow< 4,5. According REACH guidance document R11 page 82 (Version 3.0 –
June 2017), for organic substances with a log Kow value below 4.5 it is
assumed that the B criterion, i.e. a BCF value of 2000 (based on wet
weight of the organism), is not exceeded.
Moreover, considering that 60% of ready biodegradation (ThOD) was
reached within the 28-day period under the OECD 301F test, the substance
is readily biodegradable but failing the 10 days windows criteria.
Therefore it is possible to conclude that the substance is considered as
not persistent under relevant environmental conditions. In absence of
any persitence property, it is thus considered that the substance is not
PBT or vPvB based on criteria laid down in Annex XIII of
REACH. Considering in a meantime all data available, it is possible to
conclude that the bioaccumulation potential do not need to be further
