      Product Detail  


    Medical Grade Magnesium Stearate with CAS No.557-04-0 is a white fine hydrophobic powder synthesized from stearic acid and magnesium salt through refined purification and pharmaceutical-grade processing, fully complying with USP, EP and BP pharmacopoeia standards. It features uniform particle size, good fluidity, low moisture absorption, neutral mild chemical property and excellent lubricating, anti-adherent and flow-aiding functions, without irritation to human skin and digestive tract.
    Its core advantage lies in ultra-high purity and strictly controlled heavy metals, ash, microbial limits, residual solvents and free fatty acid indicators, eliminating impurity risks for oral pharmaceutical preparations. As the most widely used pharmaceutical excipient, it can effectively reduce friction between powder particles during tableting and capsule filling, prevent raw materials from sticking to punch dies and capsule shells, improve powder flowability, and make tablets surface smooth with uniform weight difference. Meanwhile, it will not interfere with the dissolution rate and stability of active pharmaceutical ingredients, compatible with most medicinal raw materials.
    Besides solid oral medicines including tablets, hard capsules, granules and chewable pills, medical grade magnesium stearate is also applicable to health supplements, vitamin tablets, effervescent tablets and cosmetic oral care products. Different from industrial grade products, this medical grade undergoes sterile treatment and microbial inspection in clean workshops, with no pathogenic bacteria detected. It is stable under normal sealed storage conditions, hard to agglomerate and long shelf life. Our factory implements full-process quality tracking and provides complete COA, pharmacopoeia compliance documents for global pharmaceutical manufacturers and health food enterprises to support registration and export customs clearance.
