Magnesium Stearate CAS 557-04-0

What is Magnesium Stearate CAS 557-04-0

Magnesium Stearate CAS 557-04-0 is a white, fine powder widely used as a pharmaceutical lubricant, anti-caking agent, and mold-release agent. Chemically, it is known as Magnesium Octadecanoate or Stearic Acid Magnesium Salt, derived from the combination of magnesium and stearic acid. This compound plays a crucial role in various industries, especially in pharmaceuticals, food processing, and cosmetics.

Chemical Composition and Properties

Magnesium Stearate is a magnesium salt of stearic acid with the chemical formula C36H70MgO4. It appears as a smooth, hydrophobic powder that is insoluble in water but soluble in alcohol and ether. Its key properties include:

• Molecular Weight: 591.27 g/mol
• Appearance: White to off-white fine powder
• Melting Point: 88–90°C
• Purity: Typically above 98% for food and pharmaceutical grades
• Functions: Acts as a lubricant, anti-adherent, and flow enhancer

These properties make it valuable for maintaining product consistency and preventing ingredients from sticking during manufacturing.

Production and Sourcing

Magnesium Stearate is produced by reacting stearic acid, a natural fatty acid commonly extracted from plant-based oils or animal fats, with magnesium salts such as magnesium oxide or magnesium carbonate. This process yields a plant-based magnesium stearate variant preferred in allergen-free and vegan formulations.

Reliable sourcing involves:

• Using high-purity raw materials free from contaminants
• Ensuring consistent particle size for smooth processing
• Meeting stringent good manufacturing practices (GMP) for pharmaceutical and food-grade quality

Blissam sources Magnesium Stearate from trusted suppliers ensuring top-grade magnesium stearate powder that meets USP and FCC standards.
