- Key result
- Surface tension:
- 45.9 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1.001 g/L
- Conclusions:
- The mean surface tension of the test item was determined to be 45.9 mN/m (standard deviation 0.06).
- Executive summary:
The surface tension of the substance was determined in an experimental study under GLP conditions according to OECD Test Guideline 115 using the harmonised OECD ring method. The mean surface tension was 45.9 mN/m (standard deviation 0.06). The test substance is considered as surface active, as its surface tension is < 60 mN/m.
Reference
The mean surface tension (n=5) was 45.9 mN/m (standard deviation = 0.06).
The test substance is considered as surface active, as its surface tension is < 60 mN/m.
Φ was calculated as 1.030 (from the 4 water tensiometer readings (mN/m): 70.5, 70.7, 70.6, 70.6).
