Description of key information

log Kow at 20°C is 3.6

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
20 °C

Additional information

The log Kow of ethylbenzene was determined using the HPLC method, wherein structurally similar reference substance (benzene, toluene, and naphthalene) were used to determine correlation of HPLC retention and log Kow. The interpolated value of log Kow = 3.6 is in good agreement with the experimentally-derived (but undocumented) value of log Kow = 3.15 reported by Hansch and Leo (1995).
