Key result
Surface tension:
75.954 mN/m
Temp.:
20 °C
Conc.:
0.25 vol%

The variation of specification factor was 0.0 mN/m.

Conclusions:
The surface tension of FAT 40278/D was determined to be 75.954 mN/m.
Executive summary:

A study was conducted to evaluate the surface tension of FAT 40278/D according to OECD Guideline 115. The determination of the surface tension was accomplished by means of a Tensiometer, using the Wilhelmy plate method. Based on the findings of the study, the surface tension of the test substance was determined to be 75.954 mN/m at room temperature ca 20 °C. The variation of specification factor was 0.0 mN/m.
