Description
Talc (CAS 14807-96-6, EC 238-877-9, HS 25262020) is a naturally occurring magnesium silicate mineral supplied under trade designations including IT FT, 5000A, 5000S, 850JS, and 15MOO. It carries no E-code designation and is classified within the Salts & Minerals category.
In plastics and polymer compounding, talc functions as a nucleating and stiffening filler, accelerating crystallisation and improving dimensional stability in polypropylene systems. In pharmaceutical tablet manufacturing, it acts as a glidant and lubricant, reducing interparticle friction to improve powder flow through compression equipment. Personal care formulators use it to modify skin feel and control sebum absorption on application.
Talc is available in multiple particle-size grades suited to pharmaceutical (Ph.Eur. compliant), cosmetic, and industrial applications. It falls under REACH registration requirements within the EU. Procurement teams should confirm grade-specific compliance documentation, including Ph.Eur. monograph conformity where pharmaceutical use is intended.
