Specific details on test material used for the study:
Batch/Lot Number: 141016
Appearance: Blue powder
Purity: ≥85.5 %
Expiry date: 19 November 2018
Storage condition: Controlled room temperature (15-25 °C, below 70 RH%)
Key result
Surface tension:
64.8 mN/m
Temp.:
20 °C
Conc.:
90 vol%

Note that the tested solution was 90% of the saturation solubility. The achieved concentration was not reported. The loading of the saturated solution was 1000 mg/L (500 mg in 500 mL).

Conclusions:
The surface tension of the aqueous solution of the test item is 64.8 mN/m.
As the surface tension value is above 60 mN/m, the test item is classified as non-surface active substance.

Description of key information

The surface tension of the aqueous solution of the test item is 64.8 mN/m.

Key value for chemical safety assessment

Surface tension:
64.8
in mN/m at 20°C and concentration in mg/L:
900
