Magnesium Stearate
Magnesium Stearate is a white, hydrophobic powder that is non-toxic and insoluble in water, with limited solubility in alcohol and ether. It has a melting point of approximately 120-130°C and can decompose at higher temperatures. This compound is known for its excellent lubricating properties and is commonly used as a flow agent in powder formulations, helping to improve the consistency and prevent clumping. In the pharmaceutical industry, magnesium stearate is widely utilized as an excipient in tablet manufacturing, enhancing the processability of active ingredients. Additionally, it serves as a release agent in various applications, including plastics and coatings, to facilitate easy removal from molds.
