- 51.5 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 other: % of saturation concentration
Any other information on results incl. tables
The results in the table below show that there is no significant change of the measured surface tension. Thus it can be concluded that equilibrium is reached. Thus the results obtained were averaged, to give the surface tension of the solution.
The result is: 51.5 mN/m
Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m).

Applicant's summary and conclusion
- Conclusions:
- The results showed that there is no significant change of the measured surface tension. Thus it can be concluded that equilibrium is reached. Thus the reults obtained were averaged, to give the surface tension of the solution. The result is 51.5 mN/m.
Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m). - Executive summary:
The surface tension of a solution of Musk R1 in ultrapure water (33.5 mg/L, ~90% of the saturation concentration) was determined according to the OECD Guideline No. 115, using the ring method.
The result is: 51.5 mN/m.
Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m).
