Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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.

Description of key information
Experimental result: 1.4787 g/cm3 at 20°C, 1.4907 g/cm3 at 25°C (extrapolated); D20/4 = 1.4908
Handbook data: 1.531 at 25°C (CRC), d20=1.5351 (Merck index), d20=1.5351 (Dose), d0=1.535 (Sax's), d=1.535 (Cond.Chem.Dict.)
Key value for chemical safety assessment
- Relative density at 20C:
- 1.52
Additional information
An experimental study was conducted, that can be related to the EC guideline, on the dehydrated substance (purity not specified). Density measurements were recorded between 24 and 55°C. Values at 20 and 25°C were calculated from the linear regression. Relative density was calculated from ratio to standard water density at 4°C.
Supporting litterature data from five handbooks are consistent between each other, despite differences in reference temperature, but are significantly higher than the experimental result.
The retained key value is the mean of the three available values for relative density 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.
