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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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= >3.2 at 23°C and at pH 7.2
Additionally, a calculated value was provided for getting a reasonable value:
Log Pow= 8.58 at 25°C
Key value for chemical safety assessment
Additional information
The solubilities in water and in octanol were determined following the ETAD method* based on the water solubility method OECD 105 and analyzed by UV/VIS spectrophotometer. The log Pow value was estimated based on individual solubility.
As the measured value is not sufficient for further assessements therefore the additional calculation was provided for getting a reasonable value. The calculation was using KOWWIN (v1.68) module of software EPI Suite v.4.11.
* The ETAD method was developed by intensive cooperation with the ETAD (Ecological and Toxicological Association of Dyes and Organic Pigments Manufacturers) and is regarded as acceptable for pigments by authorities.
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.
