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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Al3+is the predominant aluminium form at low pH (less than 5.5). As pH increases above 5.5, aluminium-hydroxide complexes formed by hydrolysis become increasingly important and dominate aqueous aluminium speciation . Al3+, depending on the composition of the medium and pH, may form Al(OH)3 or Al2O3 or AlCl or AlNO3 or AlSO4.
According to the solubility studies, the major elements found at the maximum solubility are 1054 mg/l Al and 856 mg/l Ca, for 100 g of the tested substance, ie approximatively 1%. By oral route, Aluminium chloride could be formed in the stomach, thus a read-across was made with this salt.
This GLP study was performed in accordance with OECD Test Guideline (TG) 422. Male and female Wistar rats were exposed to Al chloride basic at dose levels of 40, 200, and 1000 mg/kg body weight.
No reproduction, breeding and early post-natal developmental toxicity was observed in rats at 1000 mg/kg body weight for males and females.
Conclusion : Based on the reported results, a NOAEL for reproduction, breeding and early post-natal developmental toxicity was suggested at a level of 1000 mg/kg bw.

The study has been performed at the maximum exposure dose of 1000 mg/kg bw by oral route with aluminium chloride. No effect were seen.
Consequently, the substance is not classified .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.
