Description of key information

According to structural properties, hydrolysis is not expected/probable. Additionally, the substance is readily biodegradable.

Key value for chemical safety assessment

Additional information

According to Regulation (EC) 1907/2006, Annex VIII, Section 9.2.2.1, Column 2, the study does not need to be conducted if the substance is readily biodegradable. Diethanolamine (CAS 111-42-2) is readily biodegradable as demonstrated in a GLP study according to OECD 301 F (BASF AG, 1992; report no. 1/91/1168/26/2).


Furthermore, according to Lyman et al. (1990), Kollig et al. (1993) and Boethling & Mackay (2000) amines and alcohols are generally resistant to hydrolysis because they do not contain any labile functional groups.


Therefore, no study on the hydrolysis of diethanolamine is provided.
