Custom Manufacturing, Project Outsourcing, your Trusted Partner from China
NINGBO INNO PHARMCHEM CO.,LTD. is pleased to announce the availability of our high-quality Pharmaceutical Grade Magnesium Stearate (CAS No. 557-04-0). As a leading pharmaceutical excipient, Magnesium Stearate is indispensable in the production of solid dosage forms like tablets and capsules, playing a critical role in ensuring manufacturing efficiency and product quality.
Magnesium Stearate is a white, fine, free-flowing powder. It is characterized by a slight odor and feels creamy to the touch. Chemically, it is a salt consisting of magnesium and a mixture of solid organic acids, primarily stearic acid and palmitic acid. Its insolubility in water, ethanol, or ether is a key property that contributes to its functionality in formulations. The molecular formula for Magnesium Stearate is C36H70MgO4, and its EINECS number is 209-150-3.
In pharmaceutical manufacturing, Magnesium Stearate serves multiple vital functions. Primarily, it acts as a lubricant, preventing ingredients from sticking to the punches and dies of tablet presses or the machinery used in capsule filling. This lubrication reduces friction, which is essential for smooth and continuous high-speed production processes and helps achieve consistent tablet weight and hardness.
Beyond lubrication, Magnesium Stearate also functions as an anti-adhesive. It prevents the adherence of powder mixtures to equipment surfaces, minimizing downtime for cleaning and improving yield. Its role as a glidant is also significant, though it can have complex effects on powder flow depending on its concentration and the blend properties. When used correctly, it can improve the flow characteristics of powder mixes, ensuring uniform filling of dies and capsules.
Our Pharmaceutical Grade Magnesium Stearate meets stringent quality standards, complying with major pharmacopoeias including USP, BP, EP, and CP. We ensure rigorous quality control checks are performed, including tests for identification, solubility, loss on drying, chlorides, sulfates, lead, cadmium, and nickel, as well as the relative content of stearic and palmitic acid. These measures guarantee a product of consistent purity and performance.
Understanding the diverse needs of our clients, NINGBO INNO PHARMCHEM CO.,LTD. offers Magnesium Stearate in various packaging options, typically in 10kg or 15kg kraft bags or fiber drums. Proper storage is crucial; we recommend storing the product in a cool, dry place below 30°C, protected from humidity and pressure, to maintain its two-year validity period.
At NINGBO INNO PHARMCHEM CO.,LTD., we are committed to providing high-quality pharmaceutical excipients. If you are looking for a reliable Magnesium Stearate manufacturer or supplier, we invite you to contact us. We can provide detailed specifications, discuss pricing options, and facilitate the process to buy or purchase the required quantity for your production needs.
