Conclusions:

The aqueous solution of the test item had a mean surface tension of 70.2 mN/m.
As the surface tension was higher than 60 mN/m, the test item had no surface-active properties.

Executive summary:

The determination of the surface tension of an aqueous test substance solution was performed in accordance with the European Commission Regulation (EC) No. 440/2008, A.5 Surface tension and OECD guideline no. 115, Surface tension of aqueous solutions. The aqueous solution of the test item had a mean surface tension of 70.2 mN/m. As the surface tension was higher than 60 mN/m, the test item had no surface-active properties.

Description of key information

The aqueous solution of the test item had a mean surface tension of 70.2 mN/m.

As the surface tension was higher than 60 mN/m, the test item had no surface-active properties.
