Our state-of-the-art SGS laboratory with more than 20 specialists with professor-level knowledge ensures batch-to-batch consistency with rigorous testing procedures for heavy metals, microbiological profiles and particle size dispersion.

Product Introduction

Our product is the gold general of pharmaceutical excipients. It is an ultra-nice white powder with accurate hydrophobic residences. That is a high quality boundary lubricant that has a purity specification of ninety nine%. It's far formulated to alleviate friction related manufacturing problems in high speed pill compression and capsule filling operations. The optimal particle size distribution of the product with D50 between 5-15 micron enables a uniform dispersion in all your formulations. This flexible excipient is ideal for pharmaceutical, nutraceutical and cosmetic applications wherein reliable anti-adherent and glidant houses are had to guarantee production consistency. Produced to stringent cGMP standards and delivered fast within 3-7 working days directly from our European warehouse.

Third-Party Test Report

Heavy Metal Analysis: Our independent SGS testing confirms Lead content below 0.5ppm, Arsenic under 0.5ppm, and Mercury less than 0.1ppm, exceeding USP and European Pharmacopoeia safety thresholds for pharmaceutical applications.

Microbial Safety: Eurofins laboratory validation shows Total Plate Count ≤ 1000 CFU/g with total absence of E. coli, Salmonella and harmful organisms, guaranteeing your products satisfy the tightest hygiene standards.

Particle Size Distribution: The laser diffraction analysis shows a consistent 80-100 mesh rating. This guarantees excellent mixing homogeneity and predictable flow properties in automated dosing equipment.

Specifications

Magnesium Stearate Powder Advantages

Excellent Lubrication Performance: Our product has a BET measured specific surface area (SSA) of 10-18 m²/g and forms an ultra-thin monomolecular film around the active ingredients, reducing ejection forces by up to 60% and preventing tablet capping or lamination defects in high-speed rotary presses.

Multi-Compendial Compliance: Produced to meet USP/NF, EP, JP, and FCC criteria at the same time, so you don't need to reformulate when entering different regulatory markets and can speed up your worldwide product launch deadlines.

Optimised Fatty Acid Profile: Our extraordinarily regulated ratio of stearic to palmitic acid at 50:50 offers a homogeneous crystalline structure and predictable compressibility, ensuing in regular tablet hardness and dissolution profiles from batch to batch at some stage in the manufacturing method.

Magnesium Stearate Powder Application

High-Speed Tablet Manufacturing: Important for manufacturing lines exceeding 100,000 tablets consistent with hour, this excipient at zero.25-5.Zero% w/w attention prevents die wall adhesion, removes sticking to punch faces, and ensures clean tablet ejection even beneath extreme compression forces.

Capsule Filling Operations: Converts hard sticky natural extracts and hygroscopic mineral blends into unfastened flowing powders with normalised bulk density for correct dosing disc filling and weight uniformity compliance in completely automatic encapsulation structures.

Cosmetic Pressed Powder Formulations: Serves as a premium texturising agent for eyeshadows, blushes and compact foundations, providing waterproof 'long-put on' features, even as improving pores and skin adherence, shade payoff and sensory slip traits.

Production Process

Step 1 - Raw Material Verification: High-purity food-grade stearic and palmitic acids undergo comprehensive identity testing using Fourier-Transform Infrared Spectroscopy (FTIR) and fatty acid profiling via Gas Chromatography.

Step 2 - Precision Saponification: Pre-qualified fatty acids react with Magnesium Stearate Powder in controlled temperature reactors under continuous pH monitoring and nitrogen blanketing.

Step 3 - Multi-Stage Purification: The response mixture undergoes sequential washing cycles with pharmaceutical-grade water, followed by using vacuum filtration to remove residual reactants and ionic impurities.

Step 4 - Controlled Drying: Wet cake transfers to validated fluid bed dryers operating at precisely regulated temperatures below 80°C to prevent polymorphic transformation.

Step 5 - Micronization and Classification: Dried material passes through jet mills and air classifiers calibrated to produce target particle size distribution between 5-15 microns D50.

Step 6 - Quality Release Testing: Representative samples from each batch undergo comprehensive analysis including ICP-OES for elemental composition, microbial testing, heavy metal screening, and particle size verification.

FAQ

Q: What's the encouraged use level of the product in pill components?

A: Most medicinal drugs encompass from zero.25% to 2.0% w/w. The most useful degree would rely on your specific system mix , compression speed and system factors . Our technical group can be capable of endorse you in keeping with your production parameters.

Q: Is your product licensed vegetarian/vegan?

A: Yes, our magnesium stearate is crafted from plant primarily based stearic acid resources and is vegan licensed. Complete office work is to be had to returned your product labelling claims.

Q: How does particle size have an effect on lubrication performance?

A: smaller particles (5-10 microns) provide better surface insurance and anti-adherent characteristics, while slightly bigger debris (10-15 microns) can improve waft with out sacrificing the hardness of tablets. We will offer unique grades to satisfy your necessities.
