Magnesium silicate monohydrate (Talc), referred to as talcum powder, is a mineral composed of hydrous magnesium silicate that has served diverse industrial and consumer purposes for centuries. Magnesium silicate monohydrate (Talc) possesses several noteworthy properties, including moisture-absorption capabilities, low electrical conductivity, and high thermal stability. It is non-toxic, non-flammable, and non-irritating, rendering it highly suitable for numerous applications. Nevertheless, it is hypothesized that Magnesium silicate monohydrate (Talc) functions as a physical barrier, impeding the absorption of moisture and other substances. Magnesium silicate monohydrate (Talc) may interact with proteins and other molecules, potentially inducing alterations in their structure and activity.
