Industrial and Food Grade Sodium Sulfate Usage Differences
1. Basic Introduction of Sodium Sulfate Sodium sulfate, commonly known as Glauber’s salt, is a high-stability, cost-effective inorganic salt raw material with huge demand in global industrial manufacturing and commercial processing. It is divided into industrial grade and food grade, two types of products with completely different production processes, impurity standards and application scopes, which are not interchangeable. It is a basic auxiliary raw material essential for daily chemical, textile, papermaking, food processing and other industries, with stable chemical properties and wide industry adaptability.


2. Key Differences Between Food Grade & Industrial Grade – Industrial Grade Sodium Sulfate: Adopts conventional industrial production technology with relatively loose impurity control standards. It is mainly used for industrial auxiliary production, including detergent and soap manufacturing, float glass processing, textile printing and dyeing, papermaking filling, rubber auxiliaries and daily chemical production, focusing on basic industrial performance. – Food Grade Sodium Sulfate: Undergoes secondary high-temperature refining and ultra-fine filtration, with strict detection and limit control on heavy metals such as lead, arsenic and mercury. It fully complies with international food safety regulations, and is specially used for food processing assistance, ingredient stabilization and food texture adjustment, with extremely high safety standards.
3. Production & Quality Control Advantages To avoid cross-contamination and grade mixing risks, we implement segmented standardized production. Food grade and industrial grade sodium sulfate have independent production workshops, professional testing laboratories and classified dry storage warehouses. Each batch of products is sampled and tested strictly before delivery to ensure accurate grading, zero quality mixing and stable batch consistency. All test reports and qualification certificates are complete, fully meeting international procurement standards.
4. Customer Value & Procurement Guarantee We strictly distinguish product grades to help global buyers accurately select products according to usage scenarios, effectively avoiding production losses and qualification problems caused by wrong grade selection. With stable supply capacity and standardized quality control system, we provide high-compliance sodium sulfate products for global industrial manufacturers and food processing enterprises, reducing customer procurement risks and improving production efficiency.
