Conclusions:

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 73.2 mN/m. According to this, the test item is considered not to be surface active.

Executive summary:

The surface tension of a test solution at 90% of the test item saturation solubility in water and at 20°C was 73.2 mN/m. According to this, the test item is considered not to be surface active.

Description of key information
