*Suitable for lubricants of razole drugs, which are easy to react with magnesium stearate and cannot use magnesium stearate as lubricant.
*As a regulator and stabilizer, such as baked foods, floured thickened foods, baked potatoes and processed grains, with dosage for 0.2 %~ 1.0% of the food weight.
·Improved drug stability
· Shorter disintegration times
. Faster dissolution rates
. Enhanced lubrication efficiency
. Harder tablets in comparison to tablets produced with magnesium stearate
· Faster formulation development and scale-up
Incompatibility: Incompatible with chlorhexidine acetate.
