Key result
Surface tension:
51.1 mN/m
Temp.:
20.2 °C
Conc.:
0.516 g/L
Remarks on result:
other: The concentration of 0.516 g/L corresponds to a 90% saturated solution.
Conclusions:
The surface tension of 90 % saturated aqueous solutions of test item in water has been determined to be 51.1 mN/m at 20.2 °C. The test item was considered to be surface-active.
Executive summary:

The Surface Tension of Isobutavan was measured using a ring method according to OECD Guideline No. 115 and EC method A5.

The Surface Tension was determined to be 51.1 mN/m for a 0.516 g/l aqueous dilution of Isobutavan at a tenperature of 20.2°C. The results showed a surface tension < 60 mN/m. Therefore the test item has to be regarded as surface active.

Description of key information

The surface tension of ISOBUTAVAN has been determined to be 51.1 mN/m at 20.2°C (90% saturated solution) according to the OECD 115 guideline.

Key value for chemical safety assessment

Surface tension:
51.1
in mN/m at 20°C and concentration in mg/L:
