Results and discussion
Surface tension
- Surface tension:
- 53.9 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 000 mg/L
- Remarks on result:
- other: As the surface tension value was lower than 60 mN/m, the test item is classified as surface active substance.
Applicant's summary and conclusion
- Conclusions:
- The surface tension of the aqueous solution of the test item is 53.9 mN/m.
- Executive summary:
The objective of the study was to evaluate the surface tension of the test item applying the OECD ring method. The method is based on the measurement of the force, which is necessary to exert vertically on a ring, in contact with the surface of the liquid, in order to separate it from the surface. The determination of the surface tension was carried out using a Krüss K6 Tensiometer applying the ring method. The surface tension of the aqueous solution (1000 mg/L) of the test item is 53.9 mN/m. As the surface tension value was lower than 60 mN/m, the test item is classified as surface active substance.
