Product Overview
Sodium sulfate anhydrous (Na₂SO₄) is a highly versatile inorganic salt with significant industrial applications. Our 99% purity grade is a refined, free-flowing white crystalline powder that serves as a fundamental Detergent Builder in cleaning formulations and an essential Textile Auxiliary Agent in fabric processing. This anhydrous form offers superior stability, consistent chemical composition, and high solubility compared to hydrated variants.
Detergent Builder Applications
In detergent manufacturing, sodium sulfate anhydrous serves multiple critical functions:
- Provides bulk and density to powdered detergents for standardized dosing
- Prevents caking and improves free-flowing characteristics
- Enhances surfactant efficacy by increasing ionic strength in wash water
- Helps suspend soil particles to prevent redeposition on fabrics
- Regulates viscosity and aids in uniform granule formation during production
The 99% purity ensures minimal impurities that could cause clumping, reduced flowability, or equipment corrosion.
Textile Auxiliary Applications
In textile processing, sodium sulfate anhydrous functions as an essential electrolyte and exhausting agent:
- Promotes better dye uptake and uniform coloration on cellulose fibers
- Enhances colorfastness and reduces dye consumption
- Prevents premature dye migration in textile printing
- Serves as a leveling agent for even shade distribution
- Less corrosive than sodium chloride to stainless steel equipment
Additional Applications & Quality Assurance
Beyond primary uses, this versatile compound serves in glass manufacturing (fining agent), pulp and paper production, animal feed, pharmaceuticals, and thermal energy storage systems.
Our quality assurance includes rigorous testing of assay, moisture content, water-insoluble matter, chloride content, iron content, and pH. Available in 25 kg bags, 1-ton bulk bags, and bulk hopper truck deliveries to support continuous manufacturing operations.
