Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
logPow= < 3.0
Key value for chemical safety assessment
Additional information
The substance is an organic pigment of very low solubility in water (< 0.499 mg/L at 20°C) as well as in fat (< 10 mg/100 g of fat at 37°C), therefore the logPow could not be determined experimentally.
The logPow of the substance was calculated using 3 different programs:
- fragment method (computer program CLOGP 3.2): logPow = 3.0
- KOWWIN v1.67: logPow = 2.2
- ACD/logP v12.00, logPow = 2.79
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.
