Description of key information

The viscosity of the 4 aromatic sulphonic acids tested in liquid form ranged from 14 to 166 mm2/s at 50C. One substance has not been tested because it is a solid

Key value for chemical safety assessment

Viscosity:
166 mm²/s (static)
at the temperature of:
50 °C

Additional information

The testing was done at 50C and not 20C therefore the value used for chemical safety assessment is not expressed at 20C.
