Surface tension
Administrative data
Link to relevant study record(s)
- Endpoint:
- surface tension
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Study period:
- February 27- MArch 07 2016
- Reliability:
- 1 (reliable without restriction)
- Rationale for reliability incl. deficiencies:
- guideline study
- Qualifier:
- according to guideline
- Guideline:
- OECD Guideline 115 (Surface Tension of Aqueous Solutions)
- Qualifier:
- according to guideline
- Guideline:
- EU Method A.5 (Surface Tension)
- Qualifier:
- according to guideline
- Guideline:
- other: ASTM D1331 - 11 Standard Test Methods for Surface and Interfacial Tension of Solutions of Surface-Active Agents
- Qualifier:
- according to guideline
- Guideline:
- other: ISO 304 (1985)
- GLP compliance:
- yes (incl. QA statement)
- Type of method:
- ring method
- 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).
