Description of key information

A Koc value of 168000 L/kg is calculated for monoethanolamine oleate.

Key value for chemical safety assessment

Koc at 20 °C:
168 000

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 (log Koc = 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, the Koc value for monoethanolamine is 1.167 L/kg (log Koc = 0.067).
