Type of method:
plate method
Specific details on test material used for the study:
Test material: FAT 36034/W
Appearance: Pink powder
Surface tension:
75.056 mN/m
Temp.:
20 °C
Conc.:
0.25 vol%
Conclusions:
The surface tension of FAT 36034/W was determined to be 73.056 mN/m at room temperature ca 20 °C.
Executive summary:

The determination of the surface tension of FAT 36034/W 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 Wilhelmy Plate method was used for this purpose. Based on the findings of the study, the surface tension of FAT 36034/W was determined to be 73.056 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.005072mN/m.
