1343-88-0
Product name: Magnesium Silicate
English alias: Talc (when referring to the hydrated form); synthetic magnesium silicate;
CAS: 1343-88-0
Molecular formula: MgO3Si
Appearance: White, fine, odorless powder
Package: 20kg/bag, 25kg/bag
Magnesium Silicate is an inorganic compound that occurs naturally as minerals like talc, sepiolite, and others. The synthetic form is widely valued for its exceptional adsorption capacity, chemical inertness, and high surface area. It is a versatile material functioning as an anti-caking agent, carrier, adsorbent, and rheological modifier. Its excellent oil absorption properties make it particularly useful in a wide range of industrial applications, from plastics and paints to food and pharmaceuticals.

1. Adsorbent & Carrier: Widely used as a free-flowing and anti-caking agent in powdered foods, seasonings, and pharmaceutical preparations. Acts as a carrier for fragrances, flavors, and active ingredients.
2.Paint & Coatings: Functions as a flatting (matting) agent and extender pigment to improve suspension, sanding, and durability in paints and industrial coatings.
2. Plastics & Rubber: Used as a filler and reinforcing agent in plastics (like PP, PE) and rubber compounds to improve stiffness, heat resistance, and dimensional stability.
3.Pharmaceuticals: Commonly used as a glidant and anti-adherent in tablet manufacturing to ensure smooth powder flow and prevent sticking during compression.
4.Agriculture: Serves as a carrier for pesticides and herbicides, improving their distribution and adherence to plant surfaces.
5.Personal Care: Found in cosmetics like powders, blushes, and eyeshadows for its absorbency, smooth texture, and ability to improve spreadability.
Magnesium silicate is generally recognized as safe (GRAS) for use in food by the FDA and is considered non-toxic. It is chemically inert and non-irritating to the skin under normal conditions of use. Inhalation of fine powder dust should be avoided as it may cause respiratory irritation. Always handle with appropriate personal protective equipment (PPE) in industrial settings.
Store in a cool, dry, and well-ventilated area.
Keep the container tightly closed to prevent moisture absorption and contamination.
Avoid contact with strong acids.
Magnesium silicate is typically supplied in 20 kg or 25 kg multi-layer paper bags with inner plastic lining.
Also available in bulk bags (e.g., 500 kg, 1000 kg) upon request.
Classified as non-hazardous for transport.
