The OECD harmonized ring method was used in a GLP study based on EC A.5
and OECD 115. The surface tension of an aqueous substance solution at
90% saturation was determined to be 51.23 mN/m (at 20°C). According to
EC A.5 the substance is surface active.
The surface tension of an aqueous substance solution at 90% saturation
was determined to be 51.23 mN/m (at 20°C).
Surface tension at 20.°C:
- filtrates of 0.1 g/L suspensions is 59.6 - 60.1 mN/m
- filtrates of 0.01 g/L suspensions is 66.3 - 68.1 mN/m
