The term "talc" has four complementary meanings:

• Talc is a mineral: it is hydrated magnesium silicate.
• Talc is a rock known as steatite or soapstone, which is composed of varying proportions of the mineral talc, often combined with other minerals such as chlorite and carbonate.
• Talc is an industrial raw material in powder form, which is used in a wide range of applications.
• Talc is a cosmetic powder. This is its most widely known application—but one of the smallest in terms of consumption.
