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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
The physical and chemical properties taken into account for the Chemical Safety Assessment are:
Appearance of the substance: |
The substance is marketed as slurry (water content up to 60%) or as granular solid (water content up to 25%). The dried form is a solid. |
Melting point/freezing point: |
The initial freezing point of the marketed form is < 0° C (the substance is dispersed in water). The melting point of the substance (dry fraction) is > 300° C (dry residue of the slurry at 600° C is 39 -40% w/w). |
Boiling point: |
The initial boiling point of the marketed form is > 100° C (the substance is dispersed in water). The determination of the boiling point of the substance (dry fraction) is not required, because of the high melting point (> 300°C). |
Density: |
The density of the slurry is 1200 -1600 g/L. |
Vapour pressure: |
Vapour pressure of the marketed form (acqueous dispersion) is that of water; the determination of the vapour pressure of the substance (dry fraction) is not required, because of the high melting point (> 300°C). |
Water solubility: |
0.84 g/L (for the substance /dry fraction). The pH of the saturated solution (0.84 g/L) is 12.8. |
Viscosity: |
10 – 60 cPs (for the slurry) |
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.
