Applicant's summary and conclusion

Conclusions:
In this test conditions, the surface tension of a 90% saturated aqueous solution of the test item CERVOLIDE at 20°C was determined to be 49.8 mN/m
Due to the fact the surface tension is < 60 mN/m, the test item is classified as surface active substance.
Executive summary:

The surface tension of an aqueous solution with a concentration of 90% saturated concentration of CERVOLIDE was determined according to the OECD Guideline 115.

The surface tension of a 90% saturated aqueous solution of the test item CERVOLIDE at 20°C was determined to be 49.8 mN/m.

Due to the fact the surface tension is < 60  mN/m, the test item is classified as surface active substance.
