They are made from mineral sources such as clay and sodium carbonate. Because compounds come from the earth they may contain trace amounts of heavy metals. The levels of heavy metals in Ultramarines are regulated by the FDA, and the small amounts that may eventually be in cosmetic or personal care products do not pose a risk to human health.
