Description of key information

Using the MCI (Molecular Connectivity Index) approach of the KOCWIN v2.00 program (EPIWEB v 4.0), the Koc was estimated at 194 L/kg (weighted average value). 

Key value for chemical safety assessment

Additional information

The Koc was estimated using the MCI (Molecular Connectivity Index) approach of the KOCWIN v2.00 program (EPIWEB v 4.0; U.S. EPA (2009b)). Koc values were calculated for the individual components and an overall Koc value for amides, C12-18 (even numbered) and C18 -unsatd., N,N-bis(hydroxyethyl) was determined on a weighted-average basis using the mole fractions of all the individual components.The estimated Koc value of the substance is 194 L/kg, indicating a low to moderate potential for adsorption to organic matter.
