Sodium Stearyl Fumarate Market Summary
Introduction
Sodium Stearyl Fumarate (SSF, CAS No.: 4070-80-8) represents a specialized pharmaceutical excipient serving critical functions in solid dosage form manufacturing. This white, odorless powder functions primarily as a lubricant and anti-adherent agent in tablet and capsule formulations, typically applied at 0.5-2.0% w/w concentration. The compound offers superior performance characteristics compared to traditional lubricants such as magnesium stearate, particularly regarding its hydrophilic nature that improves tablet wettability, accelerates disintegration, and enhances dissolution rates without adversely affecting drug bioavailability. Sodium Stearyl Fumarate is FDA-approved as a regulator and stabilizer for direct addition to human food products at 0.2-1.0% by weight. Notable pharmaceutical applications include formulations for Ibuprofen, Aspirin, Clarithromycin, Ramipril, Zolpidem, Amlodipine, Nifedipine, Omeprazole, and oral antiviral medications. The global pharmaceutical excipients market, within which SSF operates, demonstrates sustained expansion driven by increasing demand for high-quality pharmaceuticals, advancing drug formulation techniques, and growing emphasis on patient compliance through improved dosage forms.
