Pure talc has a ctahedral crystal structure in which an octahedral brucite [Mg(OH) 2] sheet is sandwiched between two tetrahedral siloxane S 2 O 5 sheets. This structure is electrically neutral and will bond to an adjacent layer only through van der Waals forces. Thus, talc undergoes cleavage very readily, is very soft, and has a soapy feel.
What is Talc? Talc is a naturally occurring mineral, scientifically referred to as hydrated magnesium silicate. This naturally occurring silicate mineral boasts a unique crystal structure that makes it both soft and absorbent. Talc has found a myriad of uses across industries.

Talc is the perfect example of that. Because talc is a mineral, it's technically considered natural, right? But that certainly does not make it safe. To be sure that a product doesn't have talc, natural and organic labels are not enough. You need to look specifically for talc-free or read the ingredients list to ensure it's not on there.

Magnesium Silicate (Ultra Fine Talc) From Wikipedia, the free encyclopedia. Talc (derived from the Persian via Arabic talq) 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.
Talc - Mg 3 Si 4 O 10 (OH) 2 Allegedly named in 1546 by Georgius Agricola (Georg ) from Arabic "talq", pure, probably alluding to the color of its powder. Talc has the chemical formula - Mg 3 Si 4 O 10 (OH) 2.It is probably best know for its low hardness, although it has a micaceous structure, it is so easily deformed, that crystals are rarely seen.
Talc is usually green, white, gray, brown, or colorless. It is a translucent mineral with a pearly luster. It is the softest known mineral and is assigned a hardness of 1 on the Mohs Hardness Scale. Talc is a monoclinic mineral with a sheet structure similar to the micas. Talc has perfect cleavage that follows planes between the weakly bonded ...
