Sodium sulfate (CAS Number 7757-82-6 for anhydrous form, 7727-73-3 for decahydrate form, chemical formula Na₂SO₄) or sodium sulphate represents a versatile inorganic salt compound composed of two sodium ions, one sulfur ion, and four oxygen ions. The compound exists in various forms including anhydrous (called Yuanming powder or salt cake), decahydrate (called Glauber's salt or mirabilite), and other hydrate forms. Sodium sulfate serves diverse industrial applications across detergent manufacturing as processing aid and filler in powdered detergent production (historically consuming approximately 50% of global production), paper and pulp industry as kraft pulping cooking agent in sulfate process, glass manufacturing providing sodium oxide content for glass composition, textile industry for dyeing and printing processes, chemical manufacturing as raw material producing sodium sulfide, sodium carbonate, and other sodium compounds, and pharmaceutical applications as laxative. Global production occurs through two primary routes: approximately two-thirds as byproduct from chemical manufacturing processes particularly hydrochloric acid production via Mannheim or Hargreaves processes (combining sodium chloride with sulfuric acid) and rayon fiber manufacturing, and approximately one-third through mining of natural sodium sulfate deposits or extraction from salt lakes. The compound demonstrates important industrial utility but faces evolving demand patterns as consumer preferences shift toward compact or liquid detergents not containing sodium sulfate, affecting traditional primary application segment.
North America shows growth rates of 3.5%-4.3%, led by the United States where established kraft pulp production, mature chemical manufacturing, significant glass industry, and detergent manufacturing support steady consumption. Searles Valley Minerals Inc. operates natural sodium sulfate production from California deposits, representing high-quality natural source production. The region demonstrates mature market with stable replacement demand, specialty application growth, and declining traditional detergent applications offset by other industrial uses.
