Sodium sulphate is the sodium salt of sulphuric acid. It is a white crystalline solid of formula Na2SO4 Sodium sulphate is soluble in water and glycerine but is insoluble in ethanol. It is chemically very stable, being unreactive to most oxidising or reducing agents at normal temperatures. When dissolved in water it produces a neutral pH solution. Widely used to remove residual water from organic solvents during purification steps. Acts as a filler or bulking agent in powder laundry detergents. Helps control product viscosity and flow in both detergents and some cleaning pastes. Uses include de-frosting windows, in carpet fresheners and starch manufacture. It is also used in many powdered cleaners including laundry powders, destaining powders, carpet cleaners etc.
Glass industry: Removes air bubbles from molten glass (fining agent)
Textiles: Used in dyeing processes to promote even dye absorption on fabrics.

Sodium sulphate anhydrous (Na2SO4) is a neutral, free-flowing white powder used across detergent, textile and process industries.
- Detergent and powder blending — the standard inert filler and flow aid
- Textile dyeing — levelling agent that helps dyes strike evenly
- Glass manufacture — fining agent
- Laboratory and process drying of organic liquids
Specification and pack sizes
Minimum 99% Na2SO4, anhydrous, supplied in 25kg bags. Consistent particle size for reliable blending and metering. Pallet quantities available.
Handling and storage
Non-hazardous under CLP. Avoid breathing dust and store dry — the anhydrous form readily absorbs moisture. SDS available on request.
Frequently asked questions
What is the difference between anhydrous sodium sulphate and Glauber’s salt?
Glauber’s salt is the decahydrate (Na2SO4·10H2O) — the same compound holding ten waters of crystallisation. Anhydrous material is nearly three times stronger weight for weight.
Why is sodium sulphate used in dyeing?
It moderates the rate at which dye leaves the bath, so colour strikes level across the fabric instead of patchy. Dose depends on dye class and shade depth.
Is sodium sulphate hazardous?
It is one of the more benign industrial chemicals — not classified as hazardous, though sensible dust control applies as with any fine powder.
