Description of key information

Data from two guideline studies. 

Key value for chemical safety assessment

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

Additional information

Two separate guideline studies of surface tension were performed. The first study obtained a result of 35.4 mN/m at 20 degrees C and 1000 mg/L concentration. The second study found a value of 35 mN/m at 25 degrees C and 800 mg/L concentration. The key value is the result at 20 degrees C.
