Pharmatalc® Pharmaceutical
Talc Supplier UK

Pharmatalc® is a magnesium silicate mineral with a monoclinic crystal structure, milled to a fine, platy powder at our South African production partner's Johannesburg processing facility. Batches are irradiated in accordance with EN ISO 11137-1 by a sterilisation facility certified to EN ISO 13485, with a certificate of irradiation supplied for every batch.

Where standard industrial talc grades (MicroTalc®) serve industrial, coating and construction applications, Pharmatalc® is positioned for use in the manufacture of pharmaceutical products, personal care products and food products. The talc raw material is tested quarterly by an independent laboratory for asbestos (NIL detected) and heavy metals.
