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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Estimated based on solubility ratio:
log Pow= 0.04 at 23 °C
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 0.04
- at the temperature of:
- 23 °C
Additional information
To measure the partition coefficient of pigments utilising the standard OECD Guideline 107 is extremely difficult because of the problems associated with the inherent very low solubilities.
The procedure is used for determining the LogPow of low solubility substances, and in particular that of pigments. The method is based on the ETAD guideline ETAD-229, which in turn is based in part on the water solubility method (shaken flask) OECD 105. The LoD is 6 µg/L.
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.
