Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Additional information
The density of the test material was investigated in accordance with the standardised guidelines OECD 109, EU Method A.3 and EPA OPPTS 830.7300 under GLP conditions using a gas comparison stereopycnometer.
The density and relative density of the test material were determined using the gas comparison stereopycnometer. With this method the volume of the test material is measured in helium gas in a calibrated cylinder. The study was awarded a reliability score of 1 in accordance with the principles for assessing data quality set forth by Klimisch et al. (1997).
The test material was heated at a temperature of 120 °C for 44 minutes. The sample cell was filled with the liquefied test material and cooled in a desiccator under vacuum with silica gel as drying agent at 19.8 ± 0.1 °C in the dark for 45 minutes. The mean density and relative density of the test material were then calculated. Measurements were performed at 20.0 ± 0.5 °C.
Under the conditions of this study, the density of the test material was determined to be 1.03 g/cm³ at 20 °C. The relative density was 1.03.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
