Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
The weighted-average Koc and log Koc values of amides, C16-18(even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) using the MCI (Molecular Connectivity Index) approach of the KOCWIN v2.00 program (EPIWEB v 4.0) was estimated to be 1,354 L/kg and (log Koc = 3.1) respectively.
Key value for chemical safety assessment
- Koc at 20 °C:
- 1 354
Other adsorption coefficients
- Type:
- other: Koc
- Value in L/kg:
- 1 354
Additional information
Based on the estimated log Kow for individual components, the calculated weighted-average Koc of amides, C16-18 (even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) is estimated to be 1,354 L/kg (log Koc = 3.1) according to the KOCWIN v2.00 program (EPIWEB v 4.1; U. S. EPA (2012)).
This Koc value indicates a high potential for adsorption to organic matter. However, since the substance is readily biodegradable and the mammalian toxicokinetics data shows the substance to have a low bioaccumulation potential as well as a low BCF value, it can be assumed that amides, C16-18(even-numbered) and C18-unsatd., N,N-bis(hydroxyethyl) is not persistent or bioaccumulative in the soil or in other environmental compartments.
[LogKoc: 3.1]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
