Talc is a mineral composed primarily of magnesium, silicon and oxygen. It is a substance often found in cosmetic and personal hygiene products including baby powder, adult body powders and facial powders. Talc helps absorb moisture, freshen materials, and reduce friction to prevent rashes. Although talc has been widely used for decades, lawsuits that have come to the surface claim serious health complications linked to its use. In fact, recent studies have reported that talc increases the risk of ovarian and endometrial cancers by approximately 30 percent.
