Specific details on test material used for the study:
Name (as stated in the report): Freskomenthe
Batch: VE00419857
Expiration date: September 14, 2018
Key result
Surface tension:
50.8 mN/m
Temp.:
20 °C
Conc.:
519 mg/L
Remarks on result:
other: 90% of the saturation concentration
Conclusions:
The results 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: 50.8 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 Freskomenthe in ultrapure water (90% saturation concentration) was determined according to the OECD Guideline No. 115, using the ring method.

 

The result is:           50.8 mN/m

Therefore, according to this test, it was considered that the test material is surface active (surface tension < 60 mN/m).
