Microtalc is a hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2. Its high purity, lamellarity and high whiteness makes it an important component in the creation of pharmaceutical products.

In pharmaceuticals, talc is used primarily as carrier. It is hypoallergenic, inert and can serve as a perfect glidant in pill manufacturing. Microtalc Pharma has a consistent particle size distribution which is crucial in pharmaceuticals. Microbial properties are improved for all products by on site heat treatment. ​Microtalc Pharma grades are all produced in Amsterdam, The Netherlands.
