Sodium sulfate

Sodium sulfate (CAS 7757-82-6 ), also known as sodium sulphate, is an inorganic salt sourced in anhydrous form for use across industrial processing, pharmaceutical manufacturing, and food applications. It functions primarily as a diluent, processing aid, and carrier in formulations where a chemically neutral, water-soluble mineral salt is required for stability and consistency. In detergent manufacturing, it acts as a filler and flow-control agent in powdered formulations, improving bulk density and dispensing consistency. Kraft pulp mills use it as a make-up chemical. It is used in the sulfate pulping process to maintain the chemical balance of the recovery cycle. Textile dyeing operations rely on it to regulate dye uptake on cellulosic fibers, improving color uniformity. In pharmaceutical solid-dose manufacturing, it serves as an excipient and desiccant component, supporting moisture control in tablet and powder formulations across various batch processes. Sodium sulfate is supplied as a white anhydrous powder or granule, with the decahydrate form available for specific applications. Standard grades include food-grade ( FCC ) and industrial use. Pharmaceutical-grade options include USP and Ph. Eur. standards to ensure high purity. Packaging typically ranges from 25 kg bags to bulk quantities depending on grade and application requirements.
