Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 literature data of Harris (1990), Kollig et al. (1993) and Boethling & Mackay (2000) the structure of the test substance does not contain any functional groups sensitive to hydrolysis.

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. Dibutylamine (CAS 111 -92 -2) was found to be readily biodegradable in a modified MITI test according to OECD 301C (NITE, 1991, see IUCLID Ch. 5.2.1). Therefore, no study on hydrolysis is performed.
