Description of key information

Does not significantly accumulate in organisms.

Key value for chemical safety assessment

Additional information

According to a study on the bioaccumulation potential of 2-(2-aminoethylamino)ethanol reporting a BCF ranging from 2.1 to < 3.7, the substance is not bioaccumulative (MITI 1992). This result is supported by a measured log Kow of -1.46 at a pH ranging from 10.6 to 11 (BASF AG, 1989).

The key study is additionally supported by a few QSAR calculations. The table below lists the applied (Q)SAR models, the estimated BCF values and basic information on the applicability domain (AD). Detailed information on the model’s results and the AD are given in the endpoint study records of IUCLID Chapter 5.3.1. The selected models comply with the OECD principles for (Q)SAR models.
