Description of key information

Few data describe the partitioning behavior of ethyl centralite. All values Log Kow were received by calculation method.
However, the value of log Koc (soil) nad log Koc (sludge) was measured experimentally:
log Koc (soil) = 2.3 - 2.86
log Koc (sludge) = 1.88 - 3.12
Relationship between log Koc and log Kow for diverse chemicals is: log Koc = -0.903 log Kow + 0.094
The value of log Kow varies between 1.98 and 3.35 based on this equation.
Relationship between log Saq and log Kow for diverse solids is: log Saq = -1.022 log Kow – 0.0096 (MP – 25) + 0.381
MP melting point (72°C)
WS: 80 mg/L (key value for CSA)
The value log Kow 3.38 based on this equation responds to water solubility 80 mg/L.

Key value for chemical safety assessment

Log Kow (Log Pow):
4.2

Additional information

The value log Kow = 4.2 calculated by (Q)SAR assessment - EPI suite Software was chosen as key value for CSA with respect to bioaccumulation assessment. The higher Kow value suggests hydrophobic behaviour for ethyl centralite.
