According to KOWWIN v1.68 the estimated Log Kow of the cationic 2-ethoxy-N-ethyl-N,N-bis(2-hydroxyethyl)ethan-1-aminium fragment of the test item (SMILES code = CCOCCN(H)(CCO)(CC)CCO is -1.77.
According to KOWWIN v1.68 the estimated Log Kow of the neutral component 2-ethoxy-N,N-bis(2-ethoxyethyl)ethan-1-amine (SMILES code = CCOCCN(CCOCC)CCOCC) of the test item is 0.69.
Based on this estimate and in line with the findings of the water solubility study, the test item is not expected to be bioaccumulative.
