Overall mean calibration corrected surface tension = 53.5 mN/m (rounded to ± 0.5 mN/m)
Harkins-Jordan* corrected value = 51.0 mN/m
Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 1 g/L aqueous solution of test item was found to be 51.0 mN/m. As the result was less than 60 mN/m, the test item was considered to be surface active.
- Executive summary:
The purpose of this study was to determine the surface tension of the test item, ST2092NM.
The study was conducted in accordance with OECD Method 115 and EC Method A.5.
The surface tension of a 1 g/L aqueous solution of test item was found to be 51.0 mN/m. As the result was less than 60 mN/m, the test item was considered to be surface active.
