Description of key information

2-(2-(2-butoxyethoxy)ethoxy)ethanol does not have a high potential for adsorption to soil due to its fully miscible with water.
The Koc of triethylene glycol monobutyl ether or (2-(2-(2-butoxyethoxy)ethoxy)ethanol) can be estimated to be 10 . According to a classification scheme, this estimated Koc value suggests that triethylene glycol monobutyl or (2-(2-(2-butoxyethoxy)ethoxy)ethanol) ether is expected to have very high mobility in soil.
The estimated Soil Adsorption Coefficient was 10 L/kg measured by calculation from EPI SuiteTM v4.0 Program. This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency
These results suggest that the 2-(2-(2-butoxyethoxy)ethoxy)ethanol has high soil mobility in soil .

Additional information

Adsorption

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF100TONNESOR MORE, an adsorption study need not be conducted if:

 — based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient), or

— the substance and its degradation products decompose rapidly.

Octanol/Water Partition Coefficient of 2-(2-(2-butoxyethoxy)ethoxy)ethanol is low(log Kow = 0.51)

2-(2-(2-butoxyethoxy)ethoxy)ethanol does not have a high potential for adsorption to soil due to its fully miscible with water. The Koc of triethylene glycol monobutyl ether or (2-(2-(2-butoxyethoxy)ethoxy)ethanol) can be estimated to be 10 . According to a classification scheme, this estimated Koc value suggests that triethylene glycol monobutyl or (2-(2-(2-butoxyethoxy)ethoxy)ethanol) ether is expected to have very high mobility in soil.

 

The estimated Soil Adsorption Coefficient was 10 L/kg measured by calculation from EPI SuiteTM v4.0 Program. This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency

These results suggest that the 2-(2-(2-butoxyethoxy)ethoxy)ethanol has high soil mobility and does not have a high potential for adsorption to soil
