Description of key information

Additional information

No substance-specific data are available for monoethanolamine oleate, however read-across from monoethanolamine is used for the assessment to meet the majority of the standard REACH information requirements. 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).

 

No tests are available for hydrolysis, photodegradation in air and photolysis in water.

Monoethanolamine oleate is readily biodegradable under aerobic conditions. No simulation tests are available. The degradation rate constants used in the assessment are:

 

Degradation rate for hydrolysis

6.93E-07 d-1

Degradation rate for photolysis

6.93E-07 d-1

Degradation rate in air

0 d-1

Degradation in STP

24 d-1

Total biodegradation rate in water

0.0462 d-1

Total biodegradation rate in sediment

2.31E-03 d-1

Total biodegradation rate in soil

0.0231 d-1

 

No BCF study is available for monoethanolamine oleate. 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). In accordance with Column 2 of REACH Annex IX, the study does not need to be conducted as the substance can be expected to have a low potential for bioaccumulation (the log Kow of monoethanolamine is calculated to be -1.31).

 

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 (lof 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, 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.
