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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
logPow= 1.4-3.8 at 25°C (multi-components)
(calculated)
Key value for chemical safety assessment
Additional information
The test substance was not stable in n-octanol thus the logPow value could not be determined by experiment. The partition coefficient has to be calculated instead.
The calculation was based on fragment method using KOWWIN module of software EPI Suite.
As the test substance is a mixture of 3 major components hence the partition coefficient has been generated on the individual components and the results are given as follows:
logPow= 2.6 (of Monophthalamide-)
logPow= 1.4 (of Quinacridone )
logPow= 3.8 (of Diphthalamide-)
It can be concluded that the partition coefficient was calculated to be logPow= 1.4 - 3.8 at 25°C
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.
