There is no measured value available for the partition co-efficient of
this substance. There is however measured data for two substances either
side of it in the homologous series of these triethylene glycol ethers.
2-(2-(2 -methoxyyethoxy)ethoxy)ethanol (TEGME) has a measured value of
-1.12 for log kow whereas 2-(2-(2 -butoxyyethoxy)ethoxy)ethanol has a
value of 0.51. The value for 2-(2-(2-ethoxyyethoxy)ethoxy)ethanol
(TEGEE) will fall somewhere in between. The predicted values for the
logkow using the Epiwin QSAR are shown below:
The QSAR seems to underpredict by a value of about 0.35 to 0.45. A
corrected value of around -0.6 is predicted for the logkow and used as
the key parameter. A justification for read across/interpolation is
attached to chapter 13 of the lead registrant's dossier.
