Description of key information

The substance will not evaporate into the atmosphere from the water surface.

Key value for chemical safety assessment

Additional information

The Henry’s Law Constant of 0.000037 Pa*m3/mol at 25 °C was calculated with SRC HENRYWIN v3.20 in 2010. The data refer to the uncharged molecule of the read-across substance 2 -aminoethanol. Due to the dissociation constant of 9.5 however, the substance is almost completely protonated under environmental conditions. Considering the ionic character of the molecule under environmental pH values the volatilisation from water may be overestimated.
