Sodium Sulfate Anhydrous 99% is a premium-grade inorganic compound essential for industrial manufacturing processes. This free-flowing white crystalline powder serves as a critical raw material in detergent formulation and paper production, offering consistent chemical properties and reliable performance.
Alias:
Anhydrous sodium sulfate, saltpeter (decahydrate)
English Name:
Sodium Sulfate, Anhydrous
Chemical Formula:
Na₂SO₄
Molecular Weight:
142.04
CAS:
7757-82-6
Product Overview
Sodium sulfate anhydrous, known industrially as Yuanming fěn or thenardite, is manufactured under strict quality control protocols via the Mannheim process or natural mineral refining. With a high purity level of 99% and minimal impurities such as chloride, iron, and moisture, this compound features neutral pH, high water solubility, and excellent storage stability. Its versatility makes it ideal for applications requiring ionic strength, sulfate ion supply, or inert filler properties.
Detergent Builder Applications
In detergent manufacturing, sodium sulfate anhydrous serves as a crucial Detergent Builder with multiple functions:
Acts as filler and processing aid to standardize product measurements
Prevents caking and ensures free flow during production and storage
Enhances detergent efficiency by increasing ionic strength in wash water
Regulates viscosity in liquid detergent slurries before spray drying
Helps counteract water hardness by sequestering calcium and magnesium ions
Reduces concentration requirements for expensive active ingredients
Our 99% pure sodium sulfate helps control raw material costs while maintaining product consistency, meeting stringent quality standards for global detergent manufacturers.
Papermaking Agent Applications
Within the pulp and paper industry, sodium sulfate anhydrous functions as a fundamental Papermaking Agent:
Serves as makeup chemical to replenish sulfur losses in kraft process recovery cycles
Reduces to sodium sulfide for breaking down lignin and separating cellulose fibers
Acts as leveling agent in paper coating formulations for improved pigment dispersion
Enhances sheet smoothness, printability, and brightness
Aids in electrolyte balance and flotation efficiency for ink removal in recycling
Used as fining agent in glass manufacturing and leveling electrolyte in textile dyeing
Environmental & Safety Information
Sodium sulfate anhydrous is environmentally benign with low toxicity and high biodegradability in aqueous systems. It does not contribute to eutrophication, aligning with green formulation trends. The compound is non-flammable and non-explosive, though dust control measures are recommended during handling.
Packaging & Support: Available in 25 kg bags, 1-ton supersacks, or bulk hopper shipments. Complete technical documentation including Safety Data Sheets (SDS) and certificates of analysis (CoA) provided. Supported by reliable logistics and responsive technical service.
