Product Specification

Sodium Sulphate — Na₂SO₄

Sodium Sulphate Anhydrous is a white, odourless crystalline powder — a highly water-soluble neutral salt used as a detergent filler, textile dyeing leveling agent, glass fining agent and chemical intermediate. We supply detergent/industrial, textile, glass and reagent (LR/AR) grades, each confirmed on the lot Certificate of Analysis.

Grade selection: Specify detergent grade as a filler/builder, textile grade (Glauber’s salt) as a dyeing leveling agent, glass grade as a fining agent, or reagent (LR/AR) grade for laboratory and drying use. We match the grade to your process and certify it on the COA.

Grades & Variants

Available Grades

The same anhydrous salt, supplied to differing purity and particle profiles for each end use.

Grade	Assay	Key Limit	Typical Use
Detergent / Industrial	99% min	Chloride ≤ 0.3%	Detergent filler & processing aid
Textile (Glauber’s Salt)	99% min	Low iron	Dye leveling & exhaustion
Glass	99% min	Low insolubles	Fining agent, bubble removal
Reagent (LR / AR)	99.5% min	Chloride ≤ 0.01%	Laboratory, drying agent, extraction

Applications

Key Industry Uses

Where buyers across Africa, the GCC and South Asia deploy sodium sulphate.

Detergents & Soaps

Filler and processing aid in powder detergents; improves flowability, bulk density and formulation consistency.

Textile Dyeing

Leveling agent (Glauber’s salt) that drives even dye uptake and exhaustion in cotton and viscose dyeing.

Glass Manufacturing

Fining agent that removes air bubbles and scum from molten glass, improving clarity and quality.

Pulp & Paper

Make-up chemical in the kraft pulping process for paper and board manufacture.

Chemical Processing

Raw material for sodium sulphide and sodium silicate, and a laboratory drying agent for solvents.

Dyes & Pigments

Diluent and standardising agent in the manufacture of dyes and pigments.

Packaging

Safety & Handling

Storage & Handling

Sodium Sulphate is not classified as dangerous for transport and is low-hazard, but keep it dry.

🌧️

Keep Dry

The anhydrous salt draws moisture and can cake. Store sealed, off the floor, in a dry area.

🧤

Low Hazard

Non-toxic and non-corrosive; not IMDG regulated. Standard dust hygiene is sufficient.

🚫

Segregate from Strong Acids

Incompatible with strong acids and light metals (aluminium, magnesium). Store apart.

📄

GHS SDS Supplied

GHS-compliant Safety Data Sheet with every quotation; COA on request.

Africa, GCC & Asia Demand: Detergent powder plants across East and West Africa and South Asia, textile dyeing houses, and glass and chemical manufacturers in the GCC. SNJ Exim supplies sodium sulphate alongside soda ash and other detergent inputs so buyers consolidate sourcing with one Indian exporter.

Buyer FAQ

Common Questions

What grade of sodium sulphate do you export?▾

We supply detergent/industrial, textile (Glauber’s salt), glass and reagent (LR/AR) grades. State your application and target standard; the exact limits are confirmed on the lot Certificate of Analysis.

Is your sodium sulphate anhydrous or decahydrate?▾

Our standard export product is the anhydrous form (Na₂SO₄, 99% min). Decahydrate (Glauber’s salt crystals) can be supplied on request.

Is sodium sulphate hazardous for sea shipment?▾

No. It is not classified as dangerous goods under IMDG and ships as general cargo. A GHS SDS is supplied with every shipment.

What purity can you supply?▾

99% min as standard, and 99.5% min (reagent grade) with tighter chloride and iron limits on request — each certified on the lot COA.

What packaging is available?▾

25 kg and 50 kg HDPE/PP bags and 1000 kg FIBC jumbo bags, palletised for clean container stuffing. Private-label and custom labelling available on agreed volumes.

What is the minimum order quantity?▾

One full container load (~26–27 MT per 20′ FCL). Sample quantities can be arranged for verified industrial buyers.

What is the difference between sodium sulphate and soda ash?▾

Sodium sulphate (Na₂SO₄) is a neutral salt used as a detergent filler and dye leveling agent; soda ash (Na₂CO₃) is an alkali used in glass, detergents and pH control. We export both.

Which countries do you export sodium sulphate to?▾

Kenya, Nigeria, Tanzania, Ethiopia, South Africa, the UAE, Saudi Arabia, Oman, Bangladesh, Sri Lanka, Vietnam and Egypt, with full export documentation on every container.

Export Markets & Commercial Terms
