Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Log Kow = 3.41
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 3.41
- at the temperature of:
- 25 °C
Additional information
The substance used for estimation of log Kow is the amide derivative of Basic Brown 1 acetate. EPIWEB 4.1 does not include in its applicability domain salt forms and it is not therefore possible to use it as to predict data for this kind of substances.
However, the amide derivative has a similar polarity and can represent a conservative case for Basic Brown 1 acetate. In fact the prediction for its water solubility is in the same range of Basic Brown 1 acetate (0.0008 mg/l vs 0.1 mg/l).
The expected log Kow for Basic Brown 1 acetate is therefore considered <= 3.41.
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.
