Description of key information

The surface tension of a 90% saturated aqueous solution of Chlorendic anhydride was found to be 72.0 mN/m. As the result was greater than 60 mN/m, the test substance was not considered to be surface active.

Key value for chemical safety assessment

Surface tension:
72
in mN/m at 20°C and concentration in mg/L:
450

Additional information

The concentration of a saturated solution of chlorendic anhydride, as the acid, is 0.499 g/l (0.5 g/l). Therefore a 90% saturated solution will be 90/100 x 0.5 g/l = 0.45 g/l.
