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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Surface tension

Description of key information
Surface tension = 74.5 mN/m at 19.7°C
Key value for chemical safety assessment
- Surface tension:
- 74.5
- in mN/m at 20°C and concentration in mg/L:
- 2 000
Additional information
One reliable key study is available (Franke J, 2008), GLP compliant, performed according to the ring method as described in the EU and OECD test guidelines.
As the test item contains 49.5% of water and as the surface tension increases with the concentration of the substance, TRIQUAT Monomer has been tested at 1 g/L based on dry matter (i.e. 2 g/L of test item). This approach has been selected as a worst case, considering that if at 2g/L the substance is not surface active, it won't be surface activeat 1g/L.
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.
