Results and discussion

Surface tension
Key result
Remarks on result:
not determinable because of methodological limitations
Remarks:
The water solubility of the test substance was determined to be less than 1 mg/L. The method guidelines state that substances with a water solubility less than 1 mg/L need not be tested for surface tension.

Applicant's summary and conclusion

Conclusions:
The surface tension was not determined according to Method A.5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for the Testing of Chemicals, 27 July 1995 since the water solubility was determined to be less than 1 mg/L. The method guidelines state that substances with a water solubility less than 1 mg/L need not be tested for surface tension.
