Key result
Surface tension:
31.7 mN/m
Temp.:
20 °C
Conc.:
1 g/L
Conclusions:
Surface tension: 31.7 mN/m
Executive summary:

In the non-GLP Klimisch 1 study from Frischmann (2013) the surface tension of Reaction products of ricinoleic acid with 2-aminoethanol and maleic acid and sodium hydrogensulfite was determined according to test method EEC A.5 with the ring method at 20 °C and a concentration of 1 g/L to be 31.7 mN/m.

The result is considered acceptable for the risk assessment.
