Description of key information
The surface tension of the substance was determined in a GLP study according to test method EC A.5 and OECD guideline 115 to be 62.6 mN/m at 20.0°C following the ring method (K1; Younis, 2017).
Key value for chemical safety assessment
- Surface tension:
- 62.6
- in mN/m at 20°C and concentration in mg/L:
- 1 000
