Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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 surface tension was conducted using the ring Method which is a part of EU Method A5 of Directive 84/449/EEC. The surface tension of a 90% saturated aqueous solution of the test material has been determined as 73.0 mN/m at 20°C.
Key value for chemical safety assessment
- Surface tension:
- 73
Additional information
The surface tension was conducted using the ring Method which is a part of EU Method A5 of Directive 84/449/EEC. The surface tension was measured at intervals until a constant reading was obtained at least three times in succession. The reading was taken at the maximum force required to detach the ring from the liquid surface. The surface tension of a 90% saturated aqueous solution of the test material has been determined as 73.0 mN/m at 20°C.
Substances showing a surface tension lower than 60 mN/m should be regarded as being surface active. Therefore, the test substance is not considered to be surface active.
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.
