Description of key information

 Expert Judgement 
If released to soil, triethylene glycol monobutyl ether or (2-(2-(2-butoxyethoxy)ethoxy)ethanol) is expected to have very high mobility based upon an estimated Koc of 10. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 9.5X10-14 atm-cu m/mole. Based on % theoretical BODS of 0-24 in 5-20 days, triethylene glycol monobutyl ether or (2-(2-(2-butoxyethoxy)ethoxy)ethanol) is expected to biodegrade slowly in soil and water.

Therefore testing for Phototransformation in soils does not need to be performed.
