- 1 g/L
Applicant's summary and conclusion
- Conclusions:
- The OECD harmonized ring method was applied for the determination of the surface tension of CH03938.
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 71.2 mN/m. According to this, the test substance is considered not to be surface active.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
