- Key result
- Surface tension:
- 72.7 mN/m

- 1 021 mg/L
- Conclusions:
- The test substance is not considered to be surface active (surface tension >60 mN/m).
Reference
A value of 72.8 mN/m was taken as the correct value of the surface tension of water at 20°C. The surface tension of highly purified water at 20 °C was measured to be 69.1 mN/m. This yields a calibration factor of 72.8/69.1 = 1.054.
The solution was prepared 10 minutes before it was transferred into the tensiometer vessel. The results are shown in attachment "T-1063FM - results surface tension determinations.pdf".
The surface tension of the saturated solution of the test substance in water at a temperature of 20 °C stabilizes to 72.7 mN/m.
Description of key information
72.7 mN/m (1.021 g/L at 20°C) (EC A.5)
Key value for chemical safety assessment
- Surface tension:
- 72.7
- in mN/m at 20°C and concentration in mg/L:
- 1 021
Additional information
The test substance is not considered to be surface active (surface tension >60 mN/m).
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).
