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:
- 2014
- 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)
- Deviations:
- no
- GLP compliance:
- no
- Type of method:
- plate method
- Specific details on test material used for the study:
- FAT Number: 92368/Y
Appearance: Yellow powder - Key result
- Surface tension:
- 50.362 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.25 vol%
- Conclusions:
- The surface tension of FAT 92368/Y was determined to be 50.362 mN/m at room temperature ca 20 °C.
- Executive summary:
The determination of the surface tension of FAT 92368/Y was based on OECD Guideline No. 115: “Surface Tension of Aqueous Solutions” (1995) and on the EEC Directive 92/69, Part A, methods for the determination of physico-chemical properties, A5 “Surface Tension”, EEC Publication No. L383, December 1992. It was accomplished by means of a Tensiometer, using the Wilhelmy Platte method, which measures the force which was required to withdraw a horizontally suspended plate from the surface of the solution. Based on the findings of the study, the surface tension of FAT 92368/Y was determined to be 50.362 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.008033 mN/m.
