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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

- Transformation / dissolution:
Full test at 1 mg/L and pH 6 + 8:
The dissolved concentrations of chromium were lower than 0.5 µg/L at pH6 &8 after 7 and 28 days.
The dissolved concentrations of iron were below LOD (~0.35 µg/L) after 7 days at pH6 &8 and below 0.6 µg/L after 28 days at both pH.
The dissolved concentrations of titanium were lower than 0.1 µg/L at pH6 &8 after 7 and 28 days.
The dissolved concentrations of zinc were below 4 µg/L at pH6 &8 after 7 and below 5 µg/L at pH6 &8 after 28 days.
Full test at 100 mg/L and pH 8 for 7 days revealed maximum soluble concentrations of 4.42 µg/L Cr, 23.3 µg/L Zn, < 0.463 µg/L Fe and < 0.042 µg/L Ti.
Additional information
Studies conducted in accordance with EU guidelines are available for: appearance, melting point, relative density, particle size distribution, dustiness and transformation / dissolution.
Waivers are proposed for boiling point, vapour pressure, partition coefficient, surface tension, flash point, auto flammability, flammability for solids, pyrophoric properties, flammability in contact with water, explosiveness, oxidising properties.
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.
