Magnesium silicate (Talc)
Certifié ISO 9001:2015 & ISO 14001:2015 · Fournisseur pour laboratoires et industries depuis 2000 · Certificat d’Analyse (CoA) pour chaque lot
Magnesium silicate, commonly known as talc, is a naturally occurring mineral composed of magnesium, silicon, and oxygen. It is widely used as a filler in paper, paint, and plastics, as well as in cosmetics, pharmaceuticals, and as a lubricant in industrial applications. This fine, powdery substance is chemically stable, inert, and non-toxic, making it ideal for applications requiring purity and safety. Magnesium silicate (CAS 1343-88-0) has the molecular formula Mg₃Si₄O₁₀(OH)₂ and a molecular weight of 379.24 g/mol. It is stored at ambient conditions with no signal word classification. Molekula supplies magnesium silicate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.

Questions fréquentes
What is magnesium silicate (talc) commonly used for?
Magnesium silicate (talc) is widely used as a filler in paper, paint, and plastics; as a lubricant in cosmetics and pharmaceuticals; and in ceramics, roofing materials, and as a food additive (e.g., anti-caking agent).
What is the chemical formula and molecular weight of magnesium silicate (talc)?
The chemical formula is **Mg₃Si₄O₁₀(OH)₂** (not MgO₃Si; talc is a layered silicate mineral), and the molecular weight is approximately **379.27 g/mol** (the provided MW of 100.39 likely refers to a simplified or anhydrous form—verify exact form).
How should magnesium silicate (talc) be stored?
Store talc in a cool, dry, and well-ventilated area at ambient temperature, protected from moisture to prevent clumping or degradation.
What grades or purity levels of magnesium silicate (talc) does Molekula supply?
Molekula supplies **technical-grade talc** (industrial applications) and **pharmaceutical/food-grade talc** (where applicable), with purity levels typically ≥95% Mg₃Si₄O₁₀(OH)₂. Confirm specific grades for your use case.
Can Molekula supply magnesium silicate (talc) in bulk quantities?
Yes, Molekula can supply talc in bulk (e.g., 25kg bags, 1MT+ super sacks, or bulk containers), depending on order volume and logistics. Contact us for bulk pricing and lead times.
What documentation comes with a magnesium silicate (talc) order?
Each order includes a **Certificate of Analysis (CoA)**, **Material Safety Data Sheet (MSDS)**, and **batch-specific documentation** (e.g., heavy metals testing for food/pharma grades). Additional certifications (e.g., FDA, REACH) are available upon request.
