New paper from Ghent university. 

External lubrication is a highly valuable alternative lubrication method as it minimizes the negative impact on tablet properties encountered when using internal lubrication. In current study, experiments were performed with automated external lubrication systems implemented in a compaction simulator and rotary tablet press using three lubricants (magnesium stearate (MgSt), sodium stearyl fumarate (SSF) and glyceryl dibehenate (DBHG)).

In conclusion, the potential of external lubrication for implementation on production scale tableting equipment and during scale-up was demonstrated for multiple lubricants.
