Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Estimated based on individual solubility:

Log Pow= -4 at 20°C and at pH 7.6

Estimated on each organic parts of the salt:

Log Pow of the organic anion: 0.07

Log Pow of the organic cation: -5.2

Key value for chemical safety assessment

Log Kow (Log Pow):
-4
at the temperature of:
20 °C

Additional information

Due to the fact that the test item is a mixture the determination of the log Pow corresponding to the OECD Guideline 107 (shake flask method) is not feasible. Because the test item cannot be chromatographed under the prescribed conditions the HPLC-method (OECD Guideline 117) is also not feasible. Due to this, the log Pow can only be estimated from the single solubility of the test item in water and in n-octanol. The pH value referred to the water solubility.

Additionally, the log Pow of each part of the salt have been also calculated based on fragment method using KOWWIN (v1.68) module of software EPI Suite v.4.11.
