is a tablet lubricant for use in traditional and orally disintegrating tablets (ODT), effervescent formulas, or in formulas where the active is incompatible with Magnesium Stearate. SSF is an inert, hydrophilic to provide tablets of adequate stability, hardness, content uniformity, disintegration and dissolution rate. SSF is used as a lubricant in capsule and tablet formulations at 0.25%-2% w/w concentrations.

SSF has superior performance when compared to Magnesium Stearate

• Higher tablet hardness
• Lower ejection forces
• Less impact on disintegration times
• Less sensitive to blending time
• Semi-soluble so lower residue when in solution or effervescent
• Especially effective in ODT Tablets
• Faster formulation development and scale-up
• High degree of API compatibility
• No adverse effect on bioavailability

Use of Sodium Stearyl Fumarate

• to improve drug stability
• to avoid metallic taste of Magnesium Stearate
• for Organic Salts
• for Carbonyl-Carboxylgroup APIs
• for Sulfogroup APIs
• for high-speed direct compression
