Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
A key value of Log Koc = 3.0 has been determined for the registered substance
Key value for chemical safety assessment
- Koc at 20 °C:
- 1 000
Additional information
The Adsorption Coefficient (Koc) of the registered substance (HDI Trimer MEKO-blocked) was determined by High Performance Liquid Chromatography (Königer, 2009). The experiment was conducted in accordance with the OECD Guideline 121 and in compliance with the OECD-GLP standard. Two main peaks were identified in the chromatogram and two values of Log Koc were thus determined (first peak: Log Koc = 3.0, last peak: Log Koc = 6.6). However for the purpose of the chemical safety assessment a single value need to be derived. The value of 3.0 as Log Koc being compliant with a Log Kow value of 1.6, this value is determined as the key information for the chemical safety assessment.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
