Description of key information

Partition coefficient 2.4, 2.8 (OECD 117)

Key value for chemical safety assessment

Log Kow (Log Pow):
at the temperature of:
25 °C

Additional information

The partition coefficients of the substance were found to be 2.4 and 2.8 for the cis and trans isomers, respectively. For the key value for the chemical safety assessment the value of 2.8 has been adopted as this is the Log Pow of the major component and represents the more conservative assessment.

N.B: The determination was performed at 25 °C (temperature of the column), but the value obtained can be considered to represent the value at an unspecified, probably ambient temperature since no mention is made in the guidelines of the temperature at which the tabulated reference substances log Pow values were determined. Partition coefficients of the test and reference substances are assumed to vary with temperature in the same way.
