Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The representative test item of aluminium zirconium chloride hydroxide is characterised as a powder, with ca. 95 % of the material consisting of particles smaller than ca. 140 µm. The median particle size is D50 = 25.4 µm (D10 = 8.2 µm, D90 = 67.9 µm). Approx. 5 % of the material consist of larger particles with sizes in the range of ca. 300-800 µm. These may be primary particles or agglomerates of smaller particles.
The dustiness of this test sample was determined to be ca. 109 mg/g (ca. 11%). The MMAD of airborne dusts generated from this material is estimated as 25.4 µm (with a geometric standard deviation of 2.8). The fractional deposition in the respiratory tract of humans was estimated as follows: head: 50.12%, tracheobronchial region: 0.40%, pulmonary region: 0.64%.
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.
