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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The adsorption desorption coefficients of the substance was calculated by US EPAs software EPIWIN. The results indicates the log Koc to be 2.01.
Key value for chemical safety assessment
- Koc at 20 °C:
- 100
Additional information
The calculated estimates should be treated with some caution and may be prone to error. Quantitative Structure Activity Relationships (QSAR'S) detailed in the Technical Guidance Document (TGD) may be unreliable and therefore were not used in the estimation of adsorption coefficient. Although correction factors can be applied, it has been shown that QSAR models can significantly under estimate the adsorption coefficient of cationic substances. However, PCKOCWIN does use the experimentally determined partition coefficient value for validation of the program so for the anionic component, the estimate is considered to be more reliable. Due to the caveats involved with the program used, the calculation was performed for the ionised and unionised species of both components.
The test item is a salt and as such the components of the test item will always be present in their ionised forms. As a consequence of this, the overall result quoted will be that of the ionised species.
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.
