Description of key information

The surface tension of an aqueous solution of UNOXOL(TM) 3,4 Dialdehyde Purified Grade (Heptanes content < 0.1 % wt) at a nominal concentration of 1.08 g/L and at a temperature of 20°C is 65.6 mN/m. The surface tension of neat UNOXOL(TM) 3,4 Dialdehyde Crude Grade (Heptanes content ca. 6.0 % wt) was determined to be 33.20 mN/m at 20°C.

Key value for chemical safety assessment

Surface tension:
65.6
in mN/m at 20°C and concentration in mg/L:

Additional information

The surface tension of an aqueous solution of UNOXOL(TM) 3,4 Dialdehyde Purified Grade (Heptanes content < 0.1 % wt) at a nominal concentration of 1.08 g/L and at a temperature of 20°C is 65.6 mN/m. The surface tension of neat UNOXOL(TM) 3,4 Dialdehyde Crude Grade (Heptanes content ca. 6.0 % wt) was determined to be 33.20 mN/m at 20°C.

Based on the criteria outlined in the EEC guideline, UNOXOL(TM) 3,4 DIALDEHYDE is not surface active.
