What Is Magnesium Stearate Powder?
Bulk magnesium stearate powder is a white, fine, and odorless powder composed of magnesium salts of stearic acid, a natural fatty acid commonly derived from vegetable oils or animal fats. It is widely recognized in the pharmaceutical, food, and nutraceutical industries as a lubricant, anti-caking agent, and flow enhancer.
In supplement manufacturing, Magnesium Stearate is essential for ensuring smooth tablet pressing and capsule filling, preventing ingredients from sticking to machinery and improving overall product quality and consistency.
Is Magnesium Stearate Safe?
Magnesium stearate cas number: 557-04-0 is GRAS (Generally Recognized as Safe) and approved by FDA and EFSA for use in food and dietary supplements. It is non-toxic, non-irritating, and stable, making it suitable for long-term supplement formulations.
What is The Source of Magnesium Stearate?
Magnesium Stearate is typically plant-derived (from palm oil or hydrogenated vegetable oil) to meet clean-label and vegetarian requirements. Reputable suppliers like Maxmedchem Factory supply 99% stearic acid and combine it with magnesium oxide or magnesium hydroxide under controlled manufacturing conditions.
Manufacturing Process of Magnesium Stearate Powder
The industrial production process of Magnesium Stearate includes:
Raw Material– High-purity stearic acid (C₁₇H₃₅COOH) and magnesium source (MgO or Mg(OH)₂).
Chemical Reaction – Stearic acid reacts with magnesium oxide or hydroxide in a controlled temperature environment.
Precipitation and Washing – The product is filtered and washed to remove impurities.
Drying and Milling – The compound is dried and finely milled to achieve a uniform powder texture.
Quality Control – Tested for purity, moisture, particle size, and heavy metal content to meet USP, EP, and FCC standards.
Our process guarantees consistent particle distribution, smooth flow, and superior compressibility, ideal for high-speed tablet and capsule manufacturing.
