Log BCF of TMP C5-9 was estimated using a QSAR and equalled 1.74.(main constituent)

Key value for chemical safety assessment

BCF (aquatic species):
55.5 L/kg ww

Additional information

The Log BCFs of the main constituents of the UVCB substance TMP Fatty Acids C5 -9 were estimated using a QSAR and equalled to a range o values from 1.74 (55.5 L/kg wet weight) to 2.71 (510 L/kg wet weight). The QSAR is well documented, with a clear regression model and used for a well defined endpoint. This UVCB substance falls well within the applicability domain of the QSAR.

The value of 55.5 L/kg wet weight was used for the safety assessment.
