Description of key information
The determination of the surface tension of an aqueous solution of the test substance was based on the OECD Guideline No. 115 "Surface Tension of Aqueous Solutions" (1995). The surface tension of test substance in water was determined according to the ring method to be 72.7 mN/m at 20.0 ± 0.5 °C.
Key value for chemical safety assessment
- Surface tension:
- 72.7
- in mN/m at 20°C and concentration in mg/L:
- 1 000
