Key value for chemical safety assessment
- Relative density at 20C:
- 0.875
Additional information
There are two reliable density data for the substance. Relative density value of 0.8755 at 20°C was reported for the substance in two handbooks of reliable data which has been subject to peer review and in which the original sources are traceable. The results are considered to be reliable and used as weight of evidence. In another secondary source to which no reliability could be assigned, the substance was reported to have a density value of 0.867 g/cm3 at 20°C.
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.
