Conclusions:

Surface tension (at 20°C): 38.0 mN/m

The test item is considered to be surface-active.

Executive summary:

The surface tension of aqueous solutions of the test item was determined according to OECD guideline no. 115 [adopted on 27 July 1995] and EU test method A.5 [Directive 92/69/EEC, Official Journal L 383 A 1992] with the ring method.

Surface tension (at 20°C): 38.0 mN/m. The test item is considered to be surface-active.

The test(s) used to generate this report was(were) carried out in compliance with the principles of Good Laboratory Practice (GLP) in accordance with the currently valid German Chemical Substance Act (Chemikaliengesetz – ChemG), the underlying Commission Directive 2004/10/EC of 11 February 2004 and the relevant OECD decision of the council on 26 November 1997 and that the results fully reflect those found in the study.
