Description of key information

In the course of this study 1 g/L aqueous solutions of LZ 754 were prepared. Surface tension of these solutions was determined applying the ring method. The test was performed with the help of Krüss Easy Dyne type tensiometer. Surface Tension of 1 g/L solution is 71.5 mN/m.
As this value is higher than 60 mN/m, LZ 754 is not regarded as being surface active material according to test guideline EC A.5.

Key value for chemical safety assessment

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