Magnesium Aluminium Silicate is a high-quality, pharmaceutical-grade powder widely used in pharmaceutical applications as a thickener, stabilizer, suspending agent, and antacid. This odorless, fine white or off-white powder exhibits excellent chemical stability and disperses efficiently in aqueous solutions, though it remains insoluble in water. Designed with a layered silicate mineral structure, it possesses a pH range of 9.010.0 and a refractive rate of 1.521.54, ensuring reliable functionality across diverse formulations. Its molecular formula, AlMgSiO(OH)nHO, highlights its precise chemical composition, which includes magnesium oxide, aluminium oxide, silica, and water. With a density of 2.12.8 g/cm, it functions effectively as a swelling and suspending agent. Magnesium Aluminium Silicate is suitable for pharmaceutical, cosmetic, and food-grade applications (depending on specifications) and has a shelf life of 35 years when stored at room temperature. Note that the material decomposes before melting, maintaining its structural and functional integrity under standard conditions.
