About Talcum Powder - Safety - Facts about Talc

Talcum powder is the refined, powdery form of the softest mineral on earth: talc. Talc is an “inert” ingredient, meaning it does not generate a chemical reaction when ingested or used on the skin. People have taken advantage of its natural smoothness, safety and absorbency since ancient Egyptian times. 1.
