Sodium Stearyl Fumarate is a high-performance hydrophilic lubricant specifically designed for pharmaceutical tablet and capsule manufacturing. This pharmaceutical grade excipient effectively reduces friction between the punch and die walls during the compression process.

It offers superior chemical stability and a high melting point, making it highly compatible with sensitive active pharmaceutical ingredients (APIs). Unlike traditional lubricants, it minimizes over-lubrication issues and maintains optimal dissolution rates.

This inert additive is particularly effective in effervescent tablets and moisture-sensitive formulations due to its unique solubility profile. It ensures consistent tablet hardness and improves overall manufacturing efficiency in high-speed industrial production.

Sodium Stearyl Fumarate

  • Tablet Lubrication: Used to prevent adhesion of granules to tooling and facilitate smooth ejection during high-speed tablet compression.
  • Effervescent Formulations: Acts as a specialty lubricant that provides better solution clarity compared to metallic stearates in water-soluble products.
  •  Capsule Filling: Enhances powder flow and distribution, ensuring high dosage uniformity in hard-shell capsule manufacturing.

Inhalation of dust may cause respiratory irritation, while direct contact may lead to eye irritation. Operators should utilize N95 respirators, safety goggles, and nitrile gloves to ensure safe handling during bulk processing.
