Description of key information

According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE , a bioaccumulation study need not be conducted if:
— the substance has a low potential for bioaccumulation (for instance a log Kow ≤ 3) and/or a low potential to cross biological membranes, or
— direct and indirect exposure of the aquatic compartment is unlikely.
The estimated Log BCF of 2-(2-(2-butoxyethoxy)ethoxy)ethanol is 0.500 (BCF = 3.162 L/kg wet-wt)
The estimated BCF of 3.162 L/kg wet-wt was measured by calculation from EPI SuiteTM v4.0 Program.
This is Exposure Assessment Tools and Models made from EPA (Environmental Protection Agency).
These values would suggest very low bioaccumulation potential.
