RESULTS
WATER MEASUREMENT:
Apparent Surface Tension: 78.0 mN/m
Correction Factor: 0.9421
Corrected Surface Tension: 78.0mN/m * 0.9421 = 73.48mN/m
TEST SUBSTANCE MEASUREMENTS:
READING #1:
Apparent Surface Tension: 62.7 mN/m
Correction Factor: 0.9277
Corrected Surface Tension: 62.7mN/m * 0.9277 = 58.17mN/m
READING #2:
Apparent Surface Tension: 66.7 mN/m
Correction Factor: 0.9316
Corrected Surface Tension: 66.7mN/m * 0.9316 = 62.14mN/m
AVERAGE SURFACE TENSION READING FOR SOLUTION:
58.17mN/m + 62.14 mN/m = 60.16 mN/m

Applicant's summary and conclusion
- Conclusions:
- A solution of the test compound in water was found to have a surface tension of 60.16 mN/m (average of 58.17 mN/m and 62.14 mN/m). The substance is therefore not considered to be surface active.
- Executive summary:
In a surface tension study (20169 -47), the surface tension of the test substance has been determined to be 60.16 mN/m for a 98.1 mg/L solution at 23.8 °C using the ring method based on OECD test Method 115. The substance is therefore not considered to be surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
