Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Log Kow was estimated using three QSAR calculation programs (i.e., KOWWIN, SPARC LogP, ACD LogP) for the components in the registered substance and the average taken for them. The average log Kow values for the components ranged from 6.52 to greater than 10. Collectively, the components in this UVCB substance are expected to have log Kow >6.52.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 6.52
Additional information
Overall, the calculated logKow values for components of the registered substance, CAS 68424-31-7 ranged from 6.52 to greater than 10. They were obtained from the averaging the log Kow values predicted from three QSAR programs (i.e., US EPA Kowwin, SPARC log P and ACD Labs log P). Therefore, the components in this UVCB substance are expected to have log Kow >6.52 and are considered highly lipophilic. Collectively, these predicted log Kow values (including log Kow >10) should provide qualitatively relevant and important information that is acceptable for use in the REACH assessment of lipophilicity of the registered substance.
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.
