Additional information

2 -Aminoethanol is readily biodegradable according to OECD criteria.

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.2, column 2, a simulation study on ultimate degradation in surface water does not need to be conducted as the substance is readily biodegradable.

According to Regulation (EC) 1907/2006, Annex IX, Section 9.2.1.4, Column 2, sediment simulation testing does not need to be conducted as the substance is readily biodegradable.

However a study on the biodegradability in river water is available. The study "14CO2 Production Test in River Water" (Procter and Gamble, 1993, WESTON study no. 92 -043) is supporting the results. The study was conducted with 14C-labelled substance similar to OECD309 but with restrictions. The ready degradation is confirmed by the results after 28 days with 80 +/- 1% and after 50 days with 86.9 +/- 8.3%.
