- Temp.:
- 19.9 °C
- Conc.:
- 0.1 vol%
Any other information on results incl. tables
Calibration:
Measured value of the surface tension of water: 70.825 mN/m
Surface tension of water at the test temperature: 72.899 mN/m
Calibration factor is: 72.899/70.825 = 1.0293
The calibration factor was determined by measuring the surface tension of water and comparing with the value available in the laboratory instrument files.
The corrected value was taken from a table compiled on the basis of the Harkins-Jordan correction.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of T002113 in water (at a concentration of about 0.1%) was determined to be 68.5 mN/m at 19.9°C +/-0.4°C. Based on the criteria as outlined in the OECD Guideline, T002113 is not a surface active substance.
