Applicant's summary and conclusion
- Conclusions:
- An aqueous solution of the test item Ukanol FR 70 was prepared for the test. The concentration of this solution was determined using HPLC analysis with 56.59 mg/L.
The surface tension of the solution was determined as 62.26 mN/m at 20.2 °C. This value was measured at equilibrium after approx. two hours. The measured values in equilibrium were higher than 60 mN/m, therefore, the test item Ukanol FR was classified as not surface active. - Executive summary:
The surface tension of an aqueous solution of Ukanol FR 70 was determined according to OECD test method 115 (plate method).
