Results and discussion
Surface tension
- Key result
- Surface tension:
- 70.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
Any other information on results incl. tables
The result is a mean value of 5 different solution ages (minutes) in two runs.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of the test item was determined to be 70.4 mN/m at 20°C for a concentration of 1 g/l.
- Executive summary:
The surface tension was determined using the ring method according to the EU A.5 test guideline. The tests are run with a test item with a water solubility > 1 g/l, at constant 20°C, with two runs of 5 measurements, obtaining a mean value of the surface tension of 70.4 mN/m.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
