- Conclusions:
- The surface tension of the substance was determined to be 62.4 mN/m at a test concentration of 1.045 g/L and at 20 °C. The substance is concluded not to have surface active properties.
Reference
The measured value was corrected for calibration and a further Harkins-Jordan correction was applied.
Description of key information
The surface tension of the substance was determined, in a GLP study according to test methods EC A.5 and OECD 115, to be 62.4 mN/m at a test concentration of 1.045 g/L and at 20 °C, following the ring method (Van der Baan-Treur, 2003).
Key value for chemical safety assessment
- Surface tension:
- 62.4
- in mN/m at 20°C and concentration in mg/L:
- 1 045
Additional information
The substance is concluded not to have surface active properties.
