Basic Information

Product Description

Product   Name ： Sodium sulfate

CAS No:  7757-82-6

Form:  powder

Product Application

Detergent Industry (Traditional Major Use) :

Filler & Processing Aid : A key component in synthetic detergents (laundry powder) as a filler, anti-caking agent, and processing aid ​ to improve powder flowability and bulk density.

Glass Industry :

Finishing/Refining Agent : Used as a refining agent ​ in glass melting. Decomposes at high temperatures, releasing gases that help remove fine bubbles from the melt. Also provides a sodium source.

Pulp & Paper Industry :

Kraft Pulping Process : An important chemical for replenishing sulfur and sodium ​ in the chemical recovery cycle of the sulfate (kraft) pulping process.

Textile Dyeing Industry :

Leveling & Exhausting Agent : A critical auxiliary in the dyeing process, especially for direct, sulfur, and vat dyes, improving dye utilization and levelness.

Chemical Synthesis :

Raw Material : Used in manufacturing sodium sulfide, sodium silicate, ultramarine, and other sodium-based chemicals.

Pharmaceuticals & Food (Requires High-Purity Grades) :

Pharmaceutical Excipient : Used as a diluent and filler.

Food Additive : Used as a processing aid and anti-caking agent (limited use).

Other Applications :

Sodium silicate (water glass) production, animal feed supplement, cement accelerator, heat storage medium in cooling systems.

Packaging

25 kg/ bag

Storage

Store in a cool, dry, and well-ventilated warehouse . Protect from rain and moisture. Due to its slight hygroscopicity, keep containers tightly sealed to prevent caking. Store separately from foodstuff chemicals.
