Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 partition-coefficient was calculated by using KOWWIN v1.68. US EPA. Estimation Programs Interface Suite™ for Microsoft® Windows, v 4.10. United States Environmental Protection Agency, Washington, DC, USA. The estimated values were calculated separately for the main constituents of the target substance. A WoE approach was used to select the key value from the estimated log Kow values of the main constituents of the substance.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- -1.886
- at the temperature of:
- 25 °C
Additional information
The target substance is a multi-constituent substance. Testing is scientifically unfeasible because the substance is only provided in water solutions and it appears in dissociated form. The substance contains both organic and inorganic elements. Therefore, the estimated log Kow-values were calculated with KOWWIN v.1.68 estimation tool (US EPA 2014). The log Kow value for CSA was selected based on the estimate calculated for the main constituent (tetramethylammonium hypochlorite) of the target substance. The estimated log Kow values for the constituents were the following:
1. Tetramethylammonium chloride; log Kow: -4.18
2. Tetramethylammonium hydroxide; log Kow: -2.4745
3. Tetramethylammonium hypochlorite; log Kow: -1.8864
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).
