Applicant's summary and conclusion
- Conclusions:
- The aqueous solution of the test item had a mean surface tension of 71.59 mN/m. As the surface tension was higher than 60 mN/m, the test item had no surface-active properties.
- Executive summary:
The surface tension of the aqueous solution at 20 °C had a mean value of 71.59 mN/m. The test item had no surface-active properties.
