How Does Sodium Sulfate Anhydrous Fit Into Pharmaceutical Markets?
It primarily functions as an inert diluent and filling agent in tablet formulations, particularly in solid oral dosage forms. The inert nature ensures stability and compatibility with active pharmaceutical ingredients (APIs). Its hygroscopic property is utilized in controlled-release formulations.
Regulatory Status
Both the U.S. Food and Drug Administration (FDA) and European Medicines Agency (EMA) list sodium sulfate anhydrous as generally regarded as safe (GRAS) for pharmaceutical use. The substance must meet pharmacopeial standards such as USP, EP, or JP specifications, covering purity, moisture content, and impurity profiles.
