Sample 2: 6.8

Conclusions:

The surface tension of the test material was assessed according to OECD guideline 115 and determined to be in the range 65.5 to 66.5 mN/m at 20.2 ± 0.5 °C with a 1,03 to 1.06 g/L solution of test material in water. The test material is considered not to be surface active.

Executive summary:

The surface tension of a 1.03 to 1.06 g/L solution of test item in water has been determined to be in the range 65.5 to 66.5 mN/m at 20.2 ± 0.5 °C, using a ring method, designed to be compatible with Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008 and Method 115 of the OECD Guidelines for Testing of Chemicals, 27 July 1995. The test item is considered not to be surface active.
