Expiry date: 26 April 2019 (expiry date)
Physical Description: Clear colourless liquid
Purity/Composition: See Certificate of Analysis
Storage Conditions: At room temperature- Key result
- Surface tension:
- 54.38 mN/m
- Temp.:
- 20 °C
- Conc.:
- 90 vol%
- Remarks on result:
- other: the test solution at 90% of the test item saturation solubility in water.
- Conclusions:
- The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 54.38 mN/m. According to this, the test item is considered to be surface active.
- Executive summary:
The OECD harmonized ring method was applied for the determination of the surface tension of the test substance.
The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 54.38 mN/m. According to this, the test item is considered to be surface active.
Reference
The results of the test on the determination of the surface tension of the test solution are given inTable 3. The individual measurements were obtained with a coefficient of variation of< 0.2 mN/m.
