Results and discussion
Surface tension
- Surface tension:
- 72.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
Any other information on results incl. tables
Overall mean calibration corrected surface tension = 72.5 mN/m
Harkins-Jordan* corrected value = 71.5 mN/m
Applicant's summary and conclusion
- Conclusions:
- The surface tension of a 1 g/l solution of L-TME was found to be 71.5 mN/m. As the result is greater than 60 mN/m, L-TME was not considered to be surface active.
- Executive summary:
The surface tension of L-TME was evaluated in accordance to OECD 115. Using a 1 g/l solution of L-TME, the surface tension was found to be 71.5 mN/m, hence TME was not considered to be surface active.
