  • Applications

    Magnesium Trisilicate (CAS 14987-04-3) is an inorganic magnesium silicate used as an absorbent and processing aid across several industries. In cosmetics and personal care, it acts as an oil-absorbent powder and a carrier for actives to improve dispersion and stability of formulations in products such as powders and deodorants. In pharmaceuticals, it serves as an excipient and adsorbent carrier in tablet and suspension formulations. In coatings and inks, it is used as a filler and carrier for actives to help distribute components and stabilize formulations. In polymers and plastics, it can function as a filler or processing aid to improve handling and dimensional stability. In cleaning and household products, it may serve as a desiccant or oil-absorbing/moisture-absorbing additive to enhance texture and performance by absorbing oils and moisture.
