- Source and lot/batch No.of test material: 93589/A TE
- Appearance: white cristalline powder
Key result
Surface tension:
72.301 mN/m
Temp.:
20 °C
Remarks on result:
other: The variation of specification factor was 0.000000 mN/m.

None

Conclusions:
The surface tension of the test substance was determined to be 72.301 mN/m at the room temperature (ca. 20 °C).
Executive summary:

A study according to OECD Guideline 115 and EU Method A.5 was conducted to determine the surface tension of the test substance. The aqueous solution (0.25 % w/w) of the test substance was evaluated 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 72.301 mN/m at the room temperature (ca. 20 °C).

Description of key information
