Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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. Moreover, the substance is readily biodegradable.
Key value for chemical safety assessment
Additional information
According to Kollig et al. (1993), Boethling & Mackay (2000) and Harris (1990), the substance is generally resistant to hydrolysis because it does not contain any labile functional groups. According to Regulation (EC) No 1907/2006, Annex VIII, Section 9.2.2.1, Column 2, the study on hydrolysis as a function of pH does not need to be conducted if the substance is readily biodegradable. Diethylamine (CAS 109-89-7) was found to be readily biodegradable in a modified MITI test according to OECD 301C (68-70% degradation (O2 consumption), NITE, 1988, see IUCLID Ch. 5.2.1). The result was supported in a ready biodegradability test according to 79/831/EEC, Annex V, part C, comparable to OECD 301F (BASF AG, report no.: 01.89/0742, see IUCLID Ch. 5.2.1), where diethylamine was also found to be readily biodegradable, but failed the 10-d window (see IUCLID Ch. 5.2.1). Therefore, no study on hydrolysis is performed.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
