Does Talc Cause Cancer?

Dec 16, 2021Talc, technically known as hydrous magnesium silicate, is a mineral that's naturally found in the earth. It's made up of magnesium, silicon, oxygen, and hydrogen. In its natural state, talc may contain the mineral asbestos, a substance known to cause cancer, especially when inhaled. In 1976, manufacturers of cosmetic and personal-care

Mineral Discovery

Talc is a hydrated magnesium silicate. Talc deposits form from the transformation of high magnesium rocks by siliceous hydrothermal fluids. Most talc originates from the alteration of dolomite, or ultramafic intrusive rocks. Following this process, talc is always found in combination with other mineral(s).

reduced to two theories. The first hypothesis states that talc is a secondary mineral because it is thought that talc is derived from exposure to magnesium silicates, such as pyroxenes and amphiboles. Then water is inserted into the solution, creating a hydrous magnesium silicate (Loomis, 1948). Incidentally, that is the chemical name for talc.

Talc (Soap Stone) is the softest mineral known and formed by thermal metamorphism of siliceous dolomite rocks. It is having sheet structure of magnesium sandwiched between two layers of silica and the smooth water repellent surface of each particle slide against one another, resulting in soapy feel and exhibiting pearly luster.

Talc can become contaminated with these fibers during the mining process because asbestos (also a naturally-occurring mineral) is found in nature in close proximity to talc. This is why the selection of talc mining sites is so important, as is screening all talc batches for the presence of asbestos fibers.
