Applicant's summary and conclusion
- Conclusions:
- The OECD harmonized ring method was used for the determination of the surface tension of the reaction mass containing mainly 1,2-Dichloropropane.
The surface tension of a test solution at a concentration of 1 g/l in water and at 20°C was 71.4 mN/m. According to this, the test substance is considered not to be surface active.
