Description of key information

Surface tension of 1 g/L solution of the substance = 55.2 mN/m (19.7°C)
The substance is considered as surface-active according to EC A5 guideline criteria.

Key value for chemical safety assessment

Surface tension:
55.2
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

A fully valid, GLP, study was conducted for the determination of the surface tension of the substance, according to the OECD/EC ring method, at the maximum testing concentration of 1 g/L.

The mean result is retained as key data for purpose of CSA.
