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
- Surface tension:
- 51.358 mN/m
- Temp.:
- 20 °C
- Conc.:
- 0.25 mg/L
- Conclusions:
- The surface tension of FAT 40075/D was determined to be 51.358 mN/m at room temperature ca 20 °C.
- Executive summary:
The determination of the surface tension of FAT 40075/D 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. The determination of the surface tension was accomplished by means of a Tensiometer, using the Wilhelmy Platte method.
The test item was measured with a 0.25 % (w/w) solution. Based on the findings of the study, the surface tension of FAT 40075/D was determined to be 51.358 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.012568 mN/m.
