Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The surface tension of the substance in water is 46.7 mN/m at 20°C, according to DIN EN 14370, which is equivalent to the EU Method A.5 (Surface Tension).
Key value for chemical safety assessment
- Surface tension:
- 46.7
- in mN/m at 20°C and concentration in mg/L:
- 1 000
Additional information
The surface tension at 20 °C of a solution of the test substance in demineralized water with a concentration of 1 g/l, was determined by the plate method using a tensiometer. The following result of 46.7 mN/m at 20 °C was received. For verification of the measured values demineralized water is also measured. With a correspondence of the measured value (20 °C) = 72.7 mN/m, to the theoretical value (20 °C) = 72.75 mN/m, cited in literature, the determination of the surface tension of the test item is considered as valid.
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.
