Talcum powder is made from the mineral talc, which primarily consists of magnesium, silicon, and oxygen. Talc is a soft mineral composed of hydrated magnesium silicate with the chemical formula Mg3Si4O10(OH)2\text{Mg}_3\text{Si}4\text{O}{10}(\text{OH})_2Mg3​Si4​O10​(OH)2​. It is mined from the earth and then ground into a fine powder. This powder absorbs moisture and reduces friction, making it useful for keeping skin dry and preventing rashes. Talcum powder can be white, green, or gray with a soapy texture. In cosmetics and consumer products, talc is widely used as a moisture absorber and lubricant. While talc itself is naturally occurring, some talc deposits may contain asbestos, a known carcinogen, which has led to health concerns. However, cosmetic-grade talc used in products is supposed to be free from detectable asbestos. Talcum powder has been commonly used in baby powders, body powders, and various cosmetic products.
In summary, talcum powder is made from finely ground talc, a natural mineral composed mainly of hydrated magnesium silicate.
