Applicant's summary and conclusion

Conclusions:
The substance's surface tension was 71.5 mN/m at 20°C. As the result was greater than 60 mN/m, the test item was not considered to be surface active.
Executive summary:

The substance's surface tension was studied in accordance with EU Method A.5 and OECD Guideline 115 via a GLP-certified laboratory. Using the OECD harmonized ring method the substance (9 0% solution concentration) surface tension was evaluated to be 71.5 mN/m at 20°C. As the result was greater than 60 mN/m, the test item was not considered to be surface active.
