Description of key information

The surface tension of the aqueous solution at 20°C is 50.9 mN/m. 

Key value for chemical safety assessment

Surface tension:
50.9
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The surface tension of the test substance was determined according to OECD guideline 115 (ring method).

An aqueous solution at ambient temperature of the test substance with a concentration of 1.0 g/L was prepared. Six measurements at a temperature of 20°C were done.

The surface tension corrected according to Zuidema and Waters of the aqueous solution at 20°C is 50.9 mN/m.

Hence, the test item has surface-active properties.
