Sodium Sulphate

Updated: Dec 30, 2023

Sodium sulfate (also known as sodium sulphate or sulfate of soda) is the inorganic compound with formula Na2SO4 as well as several related hydrates. All forms are white solids that are highly soluble in water.


Sodium sulfate is mainly used for the manufacture of detergents and in the Kraft process of paper pulping, although it has many other uses. About half of the world's production is from the natural mineral form of the decahydrate (mirabilite), and half from by-products of chemical processes. It is mainly used as a filler in the manufacture of powdered home laundry detergents and in the Kraft process of paper pulping for making highly alkaline sulfides.


Applications :

The largest use is as filler in powdered home laundry detergents

Used in the Kraft process for the manufacture of wood pulp

Sodium sulfate is used as a fining agent in glass industry, to help remove small air bubbles from molten glass. It fluxes the glass and prevents scum formation of the glass melt during refining.

Sodium sulfate is added to increase the ionic strength of the solution and so helps in "levelling", reducing negative electrical charges on textile fibers so that dyes can penetrate evenly in textile industry

In the laboratory, anhydrous sodium sulfate is widely used as an inert drying agent, for removing traces of water from organic solutions


Safety : Although sodium sulfate is generally regarded as non-toxic, it should be handled with care. The dust can cause temporary asthma or eye irritation; this risk can be prevented by using eye protection and a paper mask. Transport is not limited, and no Risk Phrase or Safety Phrase applies.
