Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Butylethylamine was ready biodegradable (>90% in 21days) in the ISO 7827 (Evaluation in an Aqueous Medium of the "Ultimate" Aerobic Biodegradability of Organic Compounds - Method by Anlaysis of Dissolved Organic Carbon (DOC) test. Model calculations predict ready biodegradation.
Key value for chemical safety assessment
- Biodegradation in water:
- readily biodegradable
Additional information
Butylethylamine was degraded to >95% (day 5: 50%) in a Zahn-Wellens test for biodegradability, which is comparable to the OECD 302 B test guideline for inherent biodegradability. Thus, butylethylamine was shown to be biodegradadble (Hoechst AG, 1981).
Inherent biodegradation was also seen in two when DOC (dissolved organic carbon) was analysed in two non-guideline studies that were conducted according to ISO 7827 (BASF, 1990) and equivalent to OECD 302B (BASF, 1983).
The ready biodegradation of the substance was predicted in BIOWIN v.4.10 calculations resulted in the prediction that butylethylamine is readily biodegradable (GUBDH, 2011), and confirmed in ISO 7827 (Evaluation in an Aqueous Medium of the "Ultimate" Aerobic Biodegradability of Organic Compounds - Method by Anlaysis of Dissolved Organic Carbon (DOC) test, the decrease of the DOC was 90-100 % in 21 d (BASF, 1990), therefore the substance is considered as ready biodegradable.
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.
