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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
logKoc estimated= 3.39
Key value for chemical safety assessment
- Koc at 20 °C:
- 248.7
Additional information
The LogKoc was estimated by using calculation software EpiSuite 4.1 based on a LogKow ca. 3.4 and water solubility <0.1 mg/l.
The based structure was the amide derivative and the results are Koc: 2487 and logKoc 3.39 (>3). Even though the value of the logKoc would trigger the testing for adsorption/desorption for characterising the partitioning between environmental compartments, Basic Brown 1 Acetate is expected to have a lower adsorption potential based on its greater polar characteristic with respect to its amide derivative.
[LogKoc: 3.39]
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
