Description of key information

The measured surface tension value is 72.6 mN/m. As the surface tension value was higher than 60 mN/m, Reactive Red F03-0318 is not classified as surface active.

Key value for chemical safety assessment

Surface tension:
72.6
in mN/m at 20°C and concentration in mg/L:
1 000

Additional information

The determination of the surface tension was carried out on the test item as supplied by the sponsor, with the use of a Krüss K6 Tensiometer by OECD harmonised ring method. The measured value was found to be 72.6 mN/m. As the surface tension value was higher than 60 mN/m, Reactive Red F03-0318 is not classified as surface active.
