Description of key information

The surface tension of the substance was determined in a GLP study according to test method EC A.5 and OECD guideline 115, to be 72.4 mN/m at 21.3°C± 0.2°C, following the ring method (Weissenfeld, 2007). 

Key value for chemical safety assessment

Surface tension:
72.4
in mN/m at 20°C and concentration in mg/L:
1 025.15

Additional information

Aqueous solution of the test item was prepared by weighing 205.03 mg of test item in a 200 mL flask and filling up to the mark with double distilled water. The concentration tested for surface tension was then 1025.15 mg/L.
