Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The study of the "ready" aerobic biodegradability of DIMETHYLETHYLAMINE using the stringent OECD method 301D shows that this item reached a maximum biodegradation level of 67 % in 28 days. According to OECD Guideline 301 D, a substance is considered to be readily biodegradable if a level of 60 % degradation is reached within the 10-day period following the beginning of the degradation phase (which starts when 10 % of the TOC has been biodegraded). This 60 % must be reached during the 28-day test period.
Under the test conditions, the percentage of biodegradation of DIMETHYLETHYLAMINE reached 67 % of the ThOD at the end of the test (28 days) and this level was obtained within a 10 days window.
Ethylmethylamine is very similar to dimethylethylamine, missing one methyl group. Therefore, dimethylamine is expected to be a worst-case with regards to biodegradability. By read-across, ethylmethylamine is therefore considered readily biodegradable.

- readily biodegradable
Additional information
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.
