Talc, hydrated magnesium silicate, is typically a white or grey powder. It has a formula of H2Mg3(SiO3)4 or Mg3Si4O10(OH)2. Talc’s particular qualities such as its ability to absorb oils, odors (some of which are in fact oils), and moisture, as well as its softness and general chemical inertness, make talc a popular mineral in many manufacturing industries including: rubber, plastic, ceramics, coatings, and personal care. *Some talc powders are very fine easily become air-borne; caution should be used when handling them so as to avoid the inhalation of the material.

Plastic & Rubber
Depending on the components of the master-batch, talc can provide plastics and rubber materials with additional desirable properties, and in some cases, such as certain plastics, color as well.

Personal Care
Although talc is most well-known for its usage in baby powder, it can also be found in many other personal care and cosmetic products. Most notably, sunscreen, skin foundation & powders, and lipstick.

Additional Notes:
* Some reservoirs of talc may have slightly different mineral compositions where one or several minerals are substituted by another. Below is a quick run-down of common substitution that may occur:
– Al/Ti > Si
– Al/Fe/Mn > Mg
– Small amounts of Ca > Mg
* Different impurities in talc create different colored talcs. Colors include various shades of green, pink, and yellow.
* Soapstone, is a soft rock mainly consisting of talc. Human utilization of soapstone goes far back in time. Modern day users recognize 2 main types of soapstone: artist soapstone and architectural soapstone. Artistic soapstone is very soft and can be easily manipulated using very simple tools. Architectural soapstone contains less talc and is typically rather hard; it is used to create counter tops, fire places surroundings, sinks, tiles, and many other house objects while maintaining and utilizing talc’s natural chemical inertness, non-porous, non-hazardous properties.
