Key result

Surface tension:

72.837 mN/m

Temp.:

20 °C

Conc.:

0.25 vol%

The variation of specification factor was 0.000000 mN/m.

Conclusions:

The test substance was determined to have a surface tension of 72.837 mN/m.

Executive summary:

Surface tension of the test substance was evaluated in a study conducted according to OECD Guideline 115. It was achieved by using an aqueous solution of FAT 20063/D with the concentration of 0.25% (w/w) by means of a Tensiometer (Wilhelmy Plate Method). Based on the findings of the study, the test substance was determined to have a surface tension of 72.837 mN/m.
