Key result
Surface tension:
69.5 mN/m
Temp.:
20.4 °C
Conc.:
1 vol%
Conclusions:
The surface tension of T002615 in water (at 90% of saturation solution) was determined to be 69.5 mN/m at 20.4 deg C ± 0.2 deg C. Based on the criteria as outlined in the EEC Guideline, T002615 is not a surface-active substance.

Description of key information

The surface tension of T002615 in water (at 90% of saturation solution) was determined to be 69.5 mN/m at 20.4°C in a GLP study according to the OECD guideline 115 and EU method A.5 (Klimisch 1, Tognucci, 2003). Based on the criteria as outlined in the EEC Guideline, T002615 is not a surface-active substance.

Key value for chemical safety assessment
