Description of key information

Surface tension of a 0.00780 g/L solution of test material was determined to be 70.8 mN/m at 22.0 ± 0.5 ºC and the substance was not considered to be surface active.

Key value for chemical safety assessment

Additional information

The surface tension of the test item was determined to be 70.8 mN/m (7.80 x 10-3g/L solution) at 22.0 ± 0.5 °C, using a ring method based on ISO 304, 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 initial sample solution test material concentration was marginally higher than that determined during the definitive water solubility test but this finding was not considered to have impacted the validity of either test. The test item was considered not to be surface-active.
