- Executive summary:
A study was conducted to determine the surface tention of the test substance according to EU Method A.5. Under the study conditions, the surface tension of the test substance was determined to be 35.8 mN/m at 20°C and 0.98 g/L (White, 2004).
Referenceopen allclose all
Surface tension at CMC was established as 32.26 mN/m. CMC determined at 0.17 mM = 51 mg/L.
