- Type of method:
- OECD harmonised ring method
- Key result
- Surface tension:
- 65.4 mN/m
- Temp.:
- 20 °C
- Conc.:
- 1 g/L
- Conclusions:
- The surface tension of an aqueous substance solution at 1 g/L was determined to be 65.4 mN/m (at 20°C).
- Executive summary:
Using the OECD harmonized ring method in a GLP study according to EC A.5 and OECD 115, the surface tension of an aqueous substance solution at 1 g/L was determined to be 65.4 mN/m (at 20°C). According to the EC A.5 guideline the substance is not surface active.
