Description of key information

The surface tension of an 1 g/L aqueous solution of the substance has been determined as 73.4 mN/m at 19.9°C using the OECD Harmonized ring method (GLP-compliant study in accordance with EC A.5 and OECD 115).

Key value for chemical safety assessment

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

Additional information

The result > 60 mN/m indicates that the substance is not surface active (according to the EC A.5 guideline).
