Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Workplace exposure to silicic acid, aluminium salt is neither regulated on the EU level nor in any of the member states. Therefore, the limits of inhalation exposure to silicic acid, aluminium salt at the workplace are based on the general limit values for dust (TRGS 900, June 2008): The existing OEL for dust is 3 mg/m³ (alveolar fraction) and 10 mg/m³ (respirable fraction). It is proposed to adopt the more critical value of 3 mg/m³ as DNEL. This approach is in compliance with the ECHA "Guidance on information requirements and chemical safety assessment. Chapter R.8: Characterisation of dose [concentration]-response for human health", May 2008.
Silicic acid, aluminium salt is corrosive to eyes. However, no dose response data are available to derive DNELs. Therefore this hazard is addressed in a qualitative way by the advice to wear suitable personal protective equipment, including goggles, gloves and protective clothing.

Additional information - General Population
Silicic acid, aluminium salt is used in inclusion into or onto matrices. Therefore a risk potential to the general population is not expected at all.
Since exposure of the general public is not relevant, DNELs for the general population were not derived.
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).
