Talcum Powder and Cancer | American Cancer Society
Most concerns about a possible link between talcum powder and cancer have focused on: If people who have long-term exposure to talc particles at work, such as talc miners, are at higher risk of lung cancer from breathing them in. If talcum powder applied regularly in the genital area increases the risk of ovarian cancer.

Plate sizes in talc deposits can be as low as 1 μm and as high as 100 μm. While the largest size plates give the highest aspect ratio, they can have deleterious effects on other composite properties, and a top size of no more than about 12 μm with an average size of less than 5 μm is generally preferred.

Talc | SpringerLink
1 Geology. Talc is hydrated magnesium silicate (Mg 3 Si 4 O 10 (OH) 2 ); however, it may contain mineral impurities such as chlorites and fibrous amphiboles, calcite, magnesite, and dolomite. Talc has a characteristic perfect-basal exfoliation known as lamellarity or platiness due to low- to moderate-grade metamorphism during its formation.

U.S. Talc—Baby Powder and Much More
Talc is a hydrous silicate mineral composed of magnesium (Mg), silicon and oxygen (SiO2,silica), and water. Its chemical formula is Mg3Si4O10(OH)2. Talc is relatively pure in composition but can contain small amounts of aluminum, iron, manganese, and titanium. Talc can be white, apple green, dark green, or brown, depending on its composition.
