Applicant's summary and conclusion

Conclusions:
The surface tension of a 90% satured aqueous solution of the test item Cumin NItrile at 20°C was determined to be 59.69 mN/m (standard deviation +/-0.05 mN/m). Due to the fact that the surface tension is < 60 mN/m the test item is classified as surface-active substance.
