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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Storage stability and reactivity towards container material
Administrative data
Link to relevant study record(s)
Description of key information
The substance is stable on storage and does not react with its container.
Additional information
Storage Stability at different temperatures (-18°C, 20-25°C, 35°C, 54°C) in a polypropylene bags were measured by Sigms-Aldrich Chemie Gmbh, and the results show that the substance is stable on storage and does not react with its container.
The following decomposition rate have to be expected at:
- moderate climate <1 % (rel.) per year
- tropical climate <1 % (rel.) per year
According to “ANNEX IX- STANDARD INFORMATION REQUIREMENTS FOR SUBSTANCES MANUFACTURED OR IMPORTED IN QUANTITIES OF 100 TONNES OR MORE, study for Stability and reactivity is only required if stability of the substance is considered to be critical.
Expert Judgement
Aluminium sulphate is stable under normal ambient and anticipated storage and handling conditions of temperature and pressure. Aluminium sulphate is stable if stored under dry, cool conditions. Incompatible with oxidising agents.
However, it is hygroscopic and when exposed to moisture in air it decomposes.
Aluminium sulphate is stable on storage and does not react with its container under normal conditions of use and storage.
Therefore testing for stability and reactivity towards container material does not need to be performed.
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).
