Lubristar- Sodium Stearyl Fumarate

Lubristar- Sodium stearyl fumarate (SSF) is an inert, hydrophilic, tablet lubricant, useful in situations where other lubricating agents (i.e., magnesium stearate) fail to provide tablets of adequate stability, hardness, content uniformity, disintegration and dissolution rate. SSF is used similarly as magnesium stearate with a same lubrication efficiency. However, due to less hardness, and insufficient tablets stability provided by conventional lubricating agents, SSF is very effective. It has good compatibility with APIs such as fluvoxamine, and a perfect lubricant for high-performance formulations. SSF is used in various application such as wet granulation, dry granulation, and direct compression. Some of the properties of SSF include anti-adherent, hydrophilic, control particle size, lamellar structure, less sensitivity to blending time, high consistency compared to magnesium stearate.
