Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 log Koc of was calculated to be 3.34 based on read across from n-hexane.
Key value for chemical safety assessment
- Koc at 20 °C:
- 2 187.76
Additional information
As the log Kow of iso-hexane is >3 the adsorption/desorption endpoint cannot be waived. However, ECHA's Guidance on Information Requirements and Chemical Safety Assessment R7a Endpoint Specific Guidance (2008) indicates that before commissioning a new study alternative sources of data (e. g. QSAR) on the adsorption/desorption potential of a chemical should used. The log Koc of n-hexane was calculated to be 3.34. This has been read across to Hydrocarbons, C6, n-alkanes,cyclics, n-hexane rich.
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.
