Based an estimated Koc value of 10, determined from a EPI SuiteTM v4.1 Program., indicates that triethylene glycol monobutyl ether is expected to have very high mobility in soil.

Volatilization of triethylene glycol monobutyl ether from moist soil surfaces is not expected to be an important fate process given an estimated Henry's Law constant of 9.5X10-14 atm-cu m/mole, using a EPI SuiteTM v4.1, HENRY WIN v3.20 Program.

Triethylene glycol monobutyl ether is not expected to volatilize from dry soil surfaces based upon a vapor pressure of 2.5X10-3 mm Hg.

The theoretical BODs for triethylene glycol monobutyl ether are 0, 5, and 24% for 5, 10 and 20 days, respectively, suggesting that triethylene glycol monobutyl ether is expected to biodegrade slowly in soil.


These results suggest for 2-(2-(2-butoxyethoxy)ethoxy)ethanol that direct and indirect exposure of the terrestrial organisms and plants is unlikely.

 Therefore testing for Terrestrial toxicity does not need to be performed.
