Description of key information

The surface tension of NPEO was between 31.56 and 55.92 mN/m at 20°C (Bodsch J, 2010d).

Key value for chemical safety assessment

Surface tension:
31.56
in mN/m at 20°C and concentration in mg/L:
4.55

Additional information

The surface tension of NPEO was determined by measuring the critical micelle concentration (CMC), in accordance with OECD Guideline 115 and EU Method A.5.
