Description of key information

The test item was not considered to be surface-active.

Key value for chemical safety assessment

Surface tension:
in mN/m at 20°C and concentration in mg/L:
1 200

Additional information

The determination was carried out using a White Electrical Institute Co. Ltd. torsion balance for surface and interfacial tension measurements and a procedure based on the ISO 304 ring method. With the exception of the following deviation, the experimental procedure used was designed to be compatible with that specified in Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995.                   

The surface tension of a 1.20 g/l solution of test item has been determined to be 71.5 mN/m at 22.1 ± 0.5°C. The test item was not considered to be surface-active.
