- Conclusions:
- Surface tension of the test item is 72.9 mN/m at 1 g/l.
The test item is not considered as surface active - Executive summary:
The surface tension of test item was determined acccording to OECD guideline 115 / EU method A.5 based on the ring method and under GLP.
Surface tension of the test item is 72.9 mN/m at 1 g/l. This data is considered as a key data.
The test item is not considered as surface active
Reference
Temperature: 20.2 - 20.3 °C
Mean surface tension of the test item at 1 g/L (corrected value): 72.9 mN/m ± 1.0 mN/m.
Description of key information
72.9 mN/m at 1 g/L and at 20.2–20.3°C
The material is not considered as as surface active
Key value for chemical safety assessment
- Surface tension:
