Talc is a soft, hydrous compound composed of magnesium silicate. For centuries it has been used as a body powder as it acts as a shield, protecting sensitive skin from moisture and external irritants. Today, it is increasing in popularity for use in many cosmetic products - blushes, powder compacts and eye shadows. In pharmaceuticals, talc is an ideal excipient, used as a glidant, lubricant and diluent.
