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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Kow method:
Koc: 412.8
logKoc: 2.616
Key value for chemical safety assessment
- Koc at 20 °C:
- 412.8
Additional information
Koc of Direct Red 81 was calculated using EpiSuite 4.1., the suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
DRed81 is expected to be a substance with a low potential for adsorption, as confirmed by the partition coefficient log Kow of -2.05 (R&C, 2012).
Based on REACH regulation annex VIII column 2 (specific rules for adaptation from column 1) the study need not be conducted based on the physicochemical properties the substance can be expected to have a low potential for adsorption (e.g. the substance has a low octanol water partition coefficient).
[LogKoc: 2.616]
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.
