Applicant's summary and conclusion
- Conclusions:
- The surface tension at 20°C of an aqueous substance solution at 1 g/L was determined to be 73.0 mN/m.
- Executive summary:
Using the OECD harmonized ring method in a GLP study according to EC A.5 and OECD 115, the surface tension at 20°C of an aqueous substance solution at 1 g/L was determined to be 73.0 mN/m. According to the EC A.5 the substance is not surface active.
