Target condition according to 


guideline: 



Actual condition according to 


the study: 



Validity criteria met: 



A solution of the substance is prepared in distilled water. The concentration of this solution should be 90 % of 


the saturation solubility of the substance in water; when this concentration exceeds 1 g/ L, a concentration of 1 g/ L is used for testing.  



A concentration of 1 g/ L was used for testing as the water solubility of the test substance is 16.9 g/L. 



yes 



The measurement shall be made at approximately 20°C and shall be controlled to within ± 0.5 °C. 



Temperature during the measurement was 20.0 °C. 



yes 



The measurement results: individual readings, their arithmetic mean and the corrected mean; concentration of the solution should be stated. 



All values are reported. 



yes 


Conclusions:
The surface tension is 58.03 mN/m at 20.0 °C with a concentration of the test solution of 1.0 g/L. The test substance is surface-active.
Executive summary:

In a GLP study according to 92/69/EEC Method A.5, the surface tension of the test substance in water was determined using the ring method. The surface tension is 58.03 mN/m at 20.0 °C at a concentration of the test solution of 1.0 g/L. The testsubstance is surface-active.

Description of key information
