Description of key information
The mean surface tension of the test item at 16.3 mg/L in distilled water at 20.1 °C was 51.5 mN/m ± 0.3 mN/m. The test item was considered as surface-active in the experimental conditions used (OECD 115 guideline method).
Key value for chemical safety assessment
- Surface tension:
- 51.5
- in mN/m at 20°C and concentration in mg/L:
- 16.3
