Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
No determination was possible according to Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995.
However, during emulsification potential assessments, the test item was found to emulsify n-octanol and water, and the chemical structure of the test item is consistent with typical cationic surfactants.
Therefore, it is proposed that the test item is a surface-active substance.
Key value for chemical safety assessment
Additional information
- During water solubility testing, it was noted that the test item formed fine dispersions in water that could not be cleaned up fully. Therefore, as the final solutions would not be free from excess, undissolved test item, it was concluded that any practical testing would not be feasible.
- The test item was estimated to be essentially insoluble in water. The method guidelines state that substances with a water solubility of less than 1 mg/l need not be tested for surface tension.
No determination was possible according to Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995, due to the following reasons:
However, during emulsification potential assessments, the test item was found to emulsify n-octanol and water, and the chemical structure of the test item is consistent with typical cationic surfactants.
Therefore, it is proposed that the test item is a surface-active substance.
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.
