Alubra® sodium stearyl fumarate from DuPont is a comparatively hydrophilic lubricant widely used in capsule and tablet formulations. The fumarate moiety of Alubra® increases its melting temperature, which allows for greater functionality at high press speeds while the stearate chain maintains the lubricity of the compound and supports low ejection forces. Alubra® is also less susceptible to over-blending contributing to more flexible process conditions and reduced waste due to over blended batch failures.
Alubra® is an effective tablet binder alternative to traditional lubricants and can reduce over-lubrication and incompatibilities with certain APIs across various dosage forms.
