Conclusions:
FDCA is not surface active. The surface tension of an aqueous test substance solution at 90% of the saturation concentration was 73.5 mN/m at 20°C.

Description of key information

The substance is not surface active.

Key value for chemical safety assessment

Surface tension:
73.5

Additional information

The OECD Harmonized ring method was performed in accordance with EC A.5 and OECD 115.
