The surface tension of the test substance was investigated using
plate method in accordance with EU guideline A5. Using this method the
surface tension of the test substance was determined to be 68.4 ± 0.6
mN/m at a concentration of 0.6 mg/L and at temperature of 25°C.
The surface tension of Isopentyl p-methoxycinnamate was 68.4 mN/m at 25°C and a concentration of 0.6 mg/L
The surface tension of the test substance was measured using a
Kruss K12 tensiometer in accordance with EU method A5 (plate method).
The test was performed on solutions of test substance at 90% of the
saturation concentration in duplicate. The surface tension
of the 90% saturation test solutions 1 and 2 was 68.22 mN/m and 68.61
mN/m, respectively. The mean surface tension was 68.4±0.5 mN/m.
For calibration, the surface tension of Milli Q water was measured
at 72.28 mN/m at 24.8°C. As this value did not deviate by more than ±0.5
mN/m from the literature value of 71.90 mN/m, the calibration was
considered to be successful.
