Additional information

The surface tension of the test material was determined in accordance with the standardised guideline EU Method A.5 using a tensiometer and following the plate method. Under the conditions of the study, the surface tension of an aqueous solution (1 g/L) of test material, at 20.0 °C, was determined to be 66.1 mN/m. The test material is not considered to be a surfactant.

The study was performed in line with GLP and accepted standardised guidelines with a good level of reporting. The study was assigned a reliability score of 1 according to the criteria of Klimisch (1997) and considered suitable for assessment as an accurate reflection of the test material.

The available data are considered to be complete and the result determined, 66.1 mN/m at 20.0 °C and a concentration of 1 g/L, was taken forward for risk assessment.
