  • Applications

    Talc (powder), containing no asbestos fibers, CAS 308076-02-0, is a versatile filler and processing aid used across multiple industries. In cosmetics and personal care, it serves as a lightweight powder base and slip agent in loose powders and formulations. In polymers and plastics, talc acts as a filler and reinforcing extender to improve dimensional stability, heat resistance and workability. In coatings and inks, it provides matting and texturing effects as a functional filler. In pharmaceuticals, talc is often used as a glidant and processing excipient to improve powder flow and tablet manufacture. In household products, talc is included in powder formulations, cleaners and polishes as a mild filler and carrier. In industrial manufacturing, talc can function as a carrier, release aid, or filler to reduce costs and tailor rheology. Subject to local regulations and formulation limits.
