The partition coefficient of the substances in the category ranges from 1.09 to 2.89.
from Hansch (1995) were available for the substances methane, ethane,
propane, butane and isobutane. Data from the CRC handbook (Lide 2008)
were available for isobutane. The information is taken from reliable
peer reviewed handbooks and so can be considered reliable and suitable
for use for this endpoint. QSAR estimate data are also available for
methane, ethane, propane, butane and isobutane.
partition coefficient of methane is 1.09, ethane is 1.81, propane is
2.36, butane is 2.89 and isobutane is 2.76. The mean of the partition
coefficient values for the category is 2.52 and this has been used to
complete the 'key value for chemical safety assessment'.
