Applicant's summary and conclusion
- Conclusions:
- The OECD harmonized ring method was applied for the determination of the surface tension of the substance, in accordance with OECD 115 (1995) and EU Method A.5 (2008) and according to GLP principles. The surface tension of a test solution at a concentration of 1 g/L and at 20°C was 70.8 mN/m. According to this, the substance is considered not to be surface active.
