Additional information

The biodegradability of 2-(2-aminoethoxy)ethanol is assessed based on experimental and additional estimation data:

- A test according to OECD guideline 301A was performed using the analogous substance 2-Ethoxyethylamin, CAS 110-76-9 (BASF SE 1996). This read-across is possible, because both substances have similar physico-chemical properties and a comparable molecular structure with the same functional groups. As inoculum non-adapted municipal sludge was used. After 17 days a DOC removal of 90 -100% was measured.

 - In a test according to OECD guideline 302B using industrial activated sludge a DOC removal of 84% after 28 days was found for the target chemical itself (BASF, 1980).

(Q)SAR calculations using the estimation model CATABOL 301C (v11.16), which is implemented within the OASIS Catalogic v5.14.1.5 calculation program, revealed biodegradation rates of 71% [BOD acc. to OECD 301C] (BASF SE, 2021).

In summary, the available data indicate 2-(2-aminoethoxy)ethanol to be readily biodegradable (according to OECD criteria).
