Description of key information

not surface active

Key value for chemical safety assessment

Surface tension:
72
in mN/m at 20°C and concentration in mg/L:
2.08

Additional information

The surface activity was determined by OECD ring method according to EU Method A.5. The measured concentration of the test substance solution (2.08 mg/L) is far more than the water solubility (0.078 mg/L). The suspension was prepared by stirring an excess of the test substance in water and subsequent filtration. Therefore, the solution is considered to be a saturated solution and the study is considered to be acceptable.
