Applicant's summary and conclusion
- Conclusions:
- In a GLP-compliant study in accordance with EC A.5 and OECD 115 using the OECD harmonized ring method, the surface tension of an 1 g/L aqueous solution of the substance has been determined as 74.7 mN/m at 20°C. Because this is not < 60 mN/m, the substance is not surface active.
