Applicant's summary and conclusion
- Conclusions:
- The surface tension of an aqueous substance solution at 1 g/L was determined to be 67.11 mN/m (at 20°C).
- Executive summary:
The OECD harmonized ring method was used in a GLP study based on EC A.5 and OECD 115. The surface tension of an aqueous substance solution at 1 g/L was determined to be 67.11 mN/m (at 20°C). According to EC A.5 the substance is not surface active.
