Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

In water sodium sulfate completely dissociates into sodium and sulfate ions. The ions cannot hydrolyse. In anaerobic environments sulfate is biologically reduced to (hydrogen) sulphide by sulphate reducing bacteria, or incorporated into living organisms as source of sulphur, and thereby included in the sulphur cycle. Sodium sulphate is not reactive in aqueous solution at room temperature.

Significant bioconcentration is not expected. Sodium and sulphate ions are essential to all living organisms and their intracellular and extracellular concentrations are actively regulated. Sodium sulphate is not expected to adsorb onto soil and sediment. From Source: SODIUM SULPHATE CAS N°: 7757-82-6 OECD SIDS April 2005

Environmental Exposure and Fate.

 

In anaerobic environments sulfate is biologically reduced to (hydrogen)sulfide by sulfate reducing bacteria, or incorporated into living organisms as source of sulfur. Sodium sulfate is not reactive in aqueous solution at room temperature. In moist air sodium sulfate will take up water (hygroscopic) to form hydrates. Sodium sulfate is also soluble in glycerol, but insoluble in alcohol. Sodium sulfate has no oxidising properties, is not explosive and is non-flammable.
