Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Biodegradation in water:
- readily biodegradable
Additional information
In a MITI test (OECD 301 C) ethylamine CAS (75-04-7) was degraded to 90% (based on oxygen consumption, BOD/ThOD). A mixture of sewage, soil and natural water was used as inoculum. Monoethylamine (CAS 75-04-7) is a flammable gas at room temperature. Therefore, in order to handle safer and easier hydrochloride was used. The amount and concentration of the test substance in the study is indicated by the content of monoethylamine contained in the hydrochloride. However, the calculation of TOD and DOC was performed with the amount of hydrochloride added.
(J-CHECK databank, 1988)
This result is supported by a respirometric test (Chudoba,1969). According to this study the substance was degraded to 98.5% in 13 days. Activated sludge was used as inoculum in this study.
In conclusion, based on the available experimental data the substance is considered to be readily biodegradable, according to OECD criteria.
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.
