Talc is a mineral composed of hydrated magnesium silicate with the chemical formula H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. It occurs as foliated to fibrous masses, its monoclinic crystals being so rare as to be almost unknown. It has a perfect basal cleavage, and the folia are non-elastic, although slightly flexible. It is sectile and very soft, with a hardness of 1 (Talc is the softest of the Mohs' scale of mineral hardness). It has a specific gravity of 2.5–2.8, a waxlike or pearly luster, and is translucent to opaque. Its colour ranges from white to gray or green and it has a distinctly greasy feel. Its streak is white.
Talc is a metamorphic mineral resulting from the alteration of silicates of magnesium such as pyroxenes, amphiboles, olivine and other similar minerals. It is usually found in metamorphic rocks, often of a basic type due to the alteration of the minerals mentioned above.
A coarse grayish-green talc has been called soapstone or steatite and has been used for stoves, sinks, electrical switchboards, etc. Talc finds use as a cosmetic (talcum powder), as a lubricant, and as a filler in paper manufacture. Talc is used in baby powder, an astringent powder used for preventing rashes on the area covered by a diaper (see diaper rash). Most tailor's chalk is talc, as is the chalk often used for welding or metalworking.

talcum powder
n.
A fine, often perfumed powder made from purified talc for use on the skin.
Talc
A hydrated magnesium layer silicate (phyllosilicate) with composition close to Mg3Si4O10(OH)2. Talc commonly is white, but it may appear pale green or grayish depending on the amount of minor impurities. Talc has a greasy feel and pearly luster, and has been used as one of the hardness standards for rock-forming minerals with the value 1 on the Mohs scale. Because talc is soft, it can be scratched by fingernails. See also Hardness scales.
Talc frequently occurs in magnesium-rich metamorphosed serpentinites and siliceous dolomites. Talc-rich rocks include massive soapstones, massive steatite, and foliated talc schists.
Talc is a good insulating material. It has been commonly used in industry as a raw material for ceramics, paints, plastics, cosmetics, papers, rubber, and many other applications. See also Silicate minerals.

Think the world has gone mad concerned with raising children. You cant do this and this when it was ok for all of us we survived didn't we. The main reason with talc is what people said before they can inhale it and can be quite dangerous. I don't use anything on my daughter due to bad eczema. The doctor recommended that we do not use any lotions expect those prescribed by doc and nothing else. As all this can cause skin irrations.

From the talc fairy. You put a dirty diaper under your pillow and the next morning you wake-up and find a container of baby talcum powder in its place. The more loaded the diaper the bigger the container!

I always assumed it was ground up babies just like the name says

It used to be finely ground glass but I don't know what they use now.
