Additional information

The key study (Walker, 2008) was performed under GLP conditions and in accordance with standardised guidelines. The study was assigned a reliability score of 1 in accordance with the principles for assessing data quality as defined by Klimisch (1997). Based on the surface tension, determined to be 29.8 mN/m, and an assessment of the emulsification properties and chemical structure of the substance, the test material was determined to be a surface active material.
