Description of key information
Fatty acids, tall oil, compd. with oleylamine
The substance Fatty acids, tall oil, compd. with oleylamine is the salt of the components Fatty acids, tall oil (CAS:61790-12-3) monomers, dimer and trimers and oleylamine (CAS: 112-90-3). Once the substance is entering the aquatic environment it is expected that the substance with a surplus of water dissociates into its two main components Fatty acids, tall oil monomers, dimer and trimers and oleylamine.
Based on this assumption it is justified to evaluate Fatty acids, tall oil, compd. with oleylamine on its components with regard to its behavior in the environment.
Oleylamine:
EPISuite v4.1/Kocwin2.00: Koc estimation for oleylamine is avialable. The KOC value is 112700 (Log Koc 5.05).
An EU risk assessment for primary amines uses the following distribution rates to calculate the adsoption behaviour of primary amines including Oleylamine: Kpsoil 697 l.kg-1, Ksoil-water 1050 m3.m-3, Kpsusp 697 l.kg-1, Ksusp-water 175 m3.m-3, Kpsed 697 l.kg-1, Ksed-water 349 m3.m-3, Kpsludge 680 l.kg-1 .These data will be used for the PNEC determination for terrestrial compartment (worst case).
Fatty acids, tall oil:
EPISuite v4.1/Kocwin2.00: The Log Koc values of the main conformation isomers of the UVCB Fatty acids, tall oil monomers and dimers have been determined using KOCWIN™ v2.00 module of EPI Suite v.4.11. KOCWIN™. The log Koc for the substructure is in the range of 4.12-4.38 for the monomer structures and 7.44 - 8.30 for the dimer structures.The log Koc for the substructure is in the range of 4.12-4.38 for the monomer structures and 7.44 - 8.30 for the dimer structures. the data for the trimer structures are expected to be slightly higher than for the dimer structures.
Key value for chemical safety assessment
