Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Aluminium Zirconium Chloride Hydroxide is typically produced and placed on the market in the EU in solution form (ca. 27 -51% aqueous solutions). Such solutions are colorless to slightly yellow and odorless. The sole use of this substance is the production of wet/moist cosmetic formulations (e. g. for antiperspirant sticks, roll-ons and creams). Some amounts of Aluminium Zirconium Chloride Hydroxide are imported into the EU in powder form (usually within mixtures). Powders are generated by spray drying the solutions to reduce weight during transport. After receipt at the user, powders are turned into solutions or slurries for the use mentioned above. In consequence, the most relevant route of exposure for workers (and the general population) is via skin contact.
Nevertheless, for product stewardship reasons and to address certain REACH data requirements, a spray dried powder of pure Aluminium Zirconium Chloride Hydroxide has been prepared. Such a product is not commercially available. The powder sample was used for testing for boiling and melting point, relative density, particle size distribution and dust generation tendency (dustiness).

Additional information
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.
