Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , study for effects on terrestrial organisms and plants  need not be conducted if:
- These studies do not need to be conducted if direct and indirect exposure of the soil compartment is unlikely.

Key value for chemical safety assessment

Expert Judgement



Based an estimated Koc value of 10, determined from aEPI 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 aEPI 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.
