Description of key information
Additional information
One valid experimental result is available regarding biodegradation in fresh water for 2 -dimethylaminoethanol (according to OECD 302C, Japan Chemical Industry Ecology - Toxicology & Information Center; JETOC, 1992). As inoculum a mixture of sewage, soil and natural water was used. 60.5 % of test substance was degraded after 14 days, based on O2 consumption.
Biodegradation of dimethylethanolamine (DMAE, CAS 108-01-0) and further 42 amine compounds was determined in the supporting study: a marine biodegradability test by Eide-Haugmo et al. (2012), conducted according to the OECD guideline 306, “Biodegradability in seawater” (OECD, 1992). As test medium for the biodegradation test, aged and fortified seawater was used. After an incubation period of 28 days degradation rate of DMAE was 94 % (BOD28, based on % of ThOD).
According to these results, 2 -dimethylaminoethanol is concerned to be readily biodegradable under aerobic conditions under OECD criteria. Regarding this result, no further tests for biodegradation in water and sediment and / or in soil have to be conducted according to REACH regulation.
