Applicant's summary and conclusion

Conclusions:
The surface tension of an aqueous solution of the substance was determined to be 29.7 mN/m (at 25°C).
Executive summary:

Using the OECD harmonized ring method in a non-GLP study according to OECD 115, the surface tension of an aqueous solution of the substance was determined to be 29.7 mN/m (at 25°C). According to the EC A.5 guideline the substance is considered to be surface active.
