Calcium Stearate
Premium pharmaceutical grade lubricant and anti-adherent agent for tablet and capsule manufacturing.
Premium pharmaceutical grade lubricant and anti-adherent agent for tablet and capsule manufacturing.
Calcium Stearate is a white, waxy powder that serves as an excellent lubricant and anti-adherent in pharmaceutical formulations. It prevents sticking during tablet compression and provides smooth flow properties in manufacturing processes.
