Magnesium Stearate, identified by CAS number 557-04-0, is a chemical compound of significant importance across multiple industries. Chemically, it is the magnesium salt of stearic acid, with the molecular formula C36H70MgO4. This white, fine powder is characterized by its unctuous feel and a faint, characteristic odor. Understanding its chemical structure and properties is key to appreciating its diverse functionalities.

The molecular structure of Magnesium Stearate features a magnesium cation (Mg2+) balanced by two stearate anions. Stearic acid, a saturated fatty acid, imparts the compound with its hydrophobic nature and lubricating properties. This makes it an excellent choice for applications where friction reduction is critical, such as in the pharmaceutical industry for tablet manufacturing. When you buy Magnesium Stearate, you are acquiring a material optimized for reducing adhesion between powder particles and manufacturing equipment.

Its physical properties are also notable. It is insoluble in water and ethanol but exhibits some solubility in warm alcohols and hydrocarbons. This limited solubility contributes to its effectiveness as an anti-caking agent and its ability to form stable emulsions in certain applications. The fine powder form enhances its dispersibility and surface area coverage, crucial for its performance as a glidant and texture enhancer in cosmetics.

The functionality of Magnesium Stearate extends to its roles as a binder, emulsifier, and stabilizer in various formulations. In the food industry, it ensures product homogeneity and prevents caking. In industrial settings, it serves as a release agent in plastics and rubber.
