Description of key information

In a determination of physico-chemical properties study the test material has been determined to be 63.5 mN/m at 22.2 ± 0.5°C. The test material is considered not to be a surface-active material.
The determination was carried out using a White Electrical Institute interfacial tension balance and a procedure based on the ISO 304 ring method. With the exception of the following deviation, the experimental procedure used complied with that specified in Method A5 Surface Tension of Commission Regulation (EC) No 440/2008 of 30 May 2008.
Deviation: The surface tension result was not corrected using the Harkins-Jordan correction table as the correction is not applicable to the apparatus used. This deviation has been considered not to have affected the integrity of the study
Substances showing a surface tension lower than 60 mN/m should be regarded as being surface-active.
