Applicant's summary and conclusion
- Conclusions:
- The OECD harmonized ring method was applied for the determination of the surface tension of CH04207.
The surface tension of a test solution at a concentration of 1 g/L in water and at 20°C was 38.12 mN/m. According to this, the test item is considered to be surface active.
