Specific details on test material used for the study:
- Name of test material (as cited in study report): Isobutavan
- Physical state: colourless to pale yellow liquid
- Analytical purity: 98.7%
- Expiration date of the lot/batch: December 17, 2015
- Storage condition of test material: ambient temperature, dark
Key result
Surface tension:
51.1 mN/m
20.2 °C
0.516 g/L
Remarks on result:
other: The concentration of 0.516 g/L corresponds to a 90% saturated solution.
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.
