Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

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, 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.
