Results and discussion

Surface tension
Surface tension:
69.3 mN/m
Temp.:
20 °C
Conc.:
90 other: % of the saturation
Remarks on result:
other: concentration approximate 8mg/l

Any other information on results incl. tables

Results:

   Concentration of the test substance Surface tension at 20°C in mN/m 
 Water without test substance  -  71,7
1. Batch  90% of saturation concentration  68,6
3. Batch 

 90% of saturation concentration

 70,0

Mean of batch 1 and 3: 

 69,3

Therefore the substance is not surface active.
