Additional information
Three reliable measured relative density studies are available for the submission substance. A measured relative density of 0.9414 at 20.5 ± 0.5°C was determined for the substance using a pycnometer method in accordance with EU Test Method A.3 and in compliance with GLP. The result is considered to be reliable and is selected as key study.
Also, a relative density of 0.943 at 20°C was determined for the substance using a buoyancy method in accordance with EU Method A.3 and in compliance with GLP. In addition, a relative density value of 0.9428 at 20°C was also obtained for the substance. The key study has been selected as the most recent study.
In available secondary sources to which reliability could not be assigned, relative density values of 0.94219 at 20°C and 0.94009 at 25°C were reported for the substance. The supporting studies are in good agreement with the key study.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
