A glidant that keeps cohesive powders moving through the hopper and feed boot. Add at 0.25–1% when a formulation bridges or rat-holes, for even fill and consistent tablet weight.

Improves how evenly a blend fills the die cavity, batch after batch, without bridging or clumping in the hopper.
Used at just 0.25–1% of the blend — more doesn't improve flow further and just displaces active ingredient.
The standard fix when a cohesive powder hangs up in the hopper instead of feeding into the die consistently.
Confirm performance for your specific formulation with your own testing before a production run.

It acts as a glidant, improving how freely the powder blend flows into the die — the standard fix for weight variation caused by inconsistent fill.
0.25–1% of the total blend is typical. Too much doesn't help flow further and just displaces active ingredient.
Powder can bridge or rat-hole in the hopper, causing weight variation from tablet to tablet. See how powder flowability affects tablet compression for the full diagnosis.
4.7 out of 5, based on 3 reviews.
Fixed our powder flow issues at just under 1%. Noticeable difference in weight consistency.
Small addition, big improvement in hopper flow for our denser blend.
Does the job as a glidant. Took some trial and error to find our ideal ratio.
