Description of key information

Additional information

No adsorption/desorption study is available for monoethanolamine oleate. Therefore, the Koc was calculated with KOCWIN™ v2.00 (U. S. EPA, 2008) using the Molecular Connectivity Index as monoethanolamine oleate is an ionic substance (for details see QMRF and QPRF see Appendix A.3). The calculated Koc value is 168000 L/kg (logKoc = 5.22).

Monoethanolamine oleate is the salt of monoethanolamine and oleic acid. As oleic acid is exempted for registration according to Annex V of REACH Directive 2006/121/EC, the focus is only on the monoethanolammmonium cation of monoethanolamine oleate (for more details see reporting format for the analogue approach in Appendix A.2). Using the same calculation method, and an estimated log Kow value for monoethanolamine of -1.31, the Koc value for monoethanolamine is 1.167 L/kg (log Koc = 0.067).

No other data are available on the transport and distribution of monoethanolamine oleate in the environment.
