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 [Council Regulation (EC) No 440/2008] with the ring method.

Surface tension (at 20 °C): 37.3 mN/m

(Employed concentration: 1.0126g/l, age of solution 17 h)

Description of key information

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 [Council Regulation (EC) No 440/2008] with the ring method. Surface tension (at 20 °C): 37.3 mN/m.

According to Council regulation 440/2008 the test substance should be regarded as being a surface-active material.
