Sodium Stearyl Fumarate (SSF)

Innovative Lubrication Solutions

Estab Pharmaceuticals is at the forefront of innovation with Sodium Stearyl Fumarate (SSF), a next-generation, specialized, less hydrophobic lubricant. It offers exceptional lubrication without compromising the dissolution profile, tablet hardness, or other critical functional attributes.

With performance largely independent of processing variables like blending time and lubricant concentration, Estab Pharmaceuticals' SSF is ideal for applications such as melt-in-mouth tablets, effervescent formulations, and metal-sensitive drugs. Our commitment to excellence ensures reliable and efficient solutions for the evolving pharmaceutical industry.

Avoids problems like active incompatibility, over-lubrication, and film formation in effervescent tablets.
Useful to provide adequate stability, hardness, content uniformity, disintegration, and dissolution rate.
Improves the disintegration and friability characteristics of the tablets.
Less retardant effect on dissolution rate than Magnesium Stearate, even after extended mixing or blending.
