Applicant's summary and conclusion
- Conclusions:
- The final value for the surface tension at 20 °C is W - 67.7 mN/m. The substance is not considered to be surface active.
- Executive summary:
Study conducted to EU test guidance 84/449/EEC part A5 using the ring method, in compliance with GLP.
An aqueous solution of the substance with a concentration of 1 g/l was prepared. Six measurements at a temperature of 20 °C, every 5 min, were done
The mean value, multiplied the calibration factor yields:
WF = W F = 67.97 mN/m
The final value for the surface tension at 20 °C is:
W - 67.7 10-3 N/m
The substance is not considered to be surface active.
