Additional information

One valid experimental key result is available regarding biodegradation in fresh water for N-methylethanolamine (according to OECD 301A, BASF, 1993). After 21 days, 92 -93 % degradation were achieved. The 10 -day window was kept. The test substance is readily biodegradable according to OECD criteria.

In addition, several supporting results are reported.

The japanese biodegradation screening study (Japan Chemical Industry Ecology - Toxicology & Information Center; JETOC, 1992) was conducted according to OECD 301C. A mixed inoculum was used. After 28 days, degradation of 97 % (based on TOC removal) or 68 % (based on oxygen consumption) was achieved, respectively.

Biodegradation of N-methylaminoethanol (MMEA, CAS 109-83 -1) 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 MMEA was 94 % (BOD28, based on % of ThOD).

2 -Methylaminoethanol is readily biodegradable according to OECD criteria (BASF AG, 1993; MITI Japan, 1992, Eide-Haugmo, 2012).
