- Executive summary:
In a reliable study performed according to relevant guidelines (e.g. OECD 109) compliant with GLP, the density of the submission substance at 20°C was determined using the pycnometer method.
The density of the test item at 20ºC was 0.946 g/cm^3 (0.946 x 10^3 kg/m^3).
The relative density (D20/4) was determined as 0.946.
The individual measurements (n=2) were obtained with a deviation of = 0.01 g/cm^3.
