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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 partition coefficient (log Pow) of WP30 was determined to be: 10.5 at 20 °C by HPLC method (EC A8).
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 10.5
- at the temperature of:
- 20 °C
Additional information
Retention time of the test substance is far beyond highest calibration point, resulting in a high uncertainty of the calculated log Pow. The upper 95% confidence limit of the regression line indicates that log Pow is >8.5 anyway.
A study according to OECD () is not feasible because of solubility limits in n-octanol (4.8 µg/L) and in water (< 0.02 µg/L) that imply no possibility for partition determination by concentration measurement above 240.
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.
