Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

No test data to address the ready biodegradability of the target substance is available. Therefore, information for two source substances, 2-aminoethanol (ethanolamine; CAS No. 141-43-5) and propionic acid (CAS No. 79-09-4), are presented to address this endpoint. The basis for this read-across approach is that the inoculum is expected to rapidly transform the target substance into the two source substances. 


The ready biodegradability of propionic acid was studied in a Warburg Respirometer test. The test substance was degraded to 74% after 30 days. The substance propionic acid was shown to be readily biodegradable under the conditions of the test.


The ready biodegradability of 2-aminoethanol was studied in a Sturm test equivalent to OECD 301B. The test substance was degraded to 91.8 % after 28 days. The substance 2-aminoethanol was shown to be readily and ultimately biodegradable under the conditions of the test. Review of the data presented in the graphical representation of the % degradation over time confirms the sample degraded reaching approximate 10% degradation around day 2 and >80% around day 12. Therefore, the sample met the 10 -day window criteria.


Since both ethanolamine and propionic acid have been shown to be readily biodegradable, the target substance can confidently be predicted also to be readily biodegradable.
