agriculture and food
Talc is an effective anti-caking agent, dispersing agent and die lubricant and therefore helps animal feed and fertilizer plants to function more efficiently. In premixes and agricultural chemicals, it makes an ideal inert carrier. Talc also is used as an anti-stick coating agent in a number of popular foods including chewing gum, boiled sweets, cured meats, and for rice polishing. In olive oil production, as a processing aid, it increases yield and improves the clarity of the oil.

Talc is a phyllosilicate which imparts a wide range of functions to floor and wall tiles and sanitaryware, tableware, refractories and technical ceramics. In traditional building ceramics (tiles and sanitaryware), it is used essentially as a flux, enabling firing temperatures and cycles to be reduced.In refractory applications, chlorite-rich talc is transformed into cordierite to improve thermal shock resistance. For steatite ceramics, talcs with a microcrystalline are the most appropriate. During firing, the talc is transformed into enstatite, which possesses electro-insulating properties.  As for very low iron content talcs, they are particularly suitable for use in frit, engobe and glaze compositions.

Talc confers a whole range of benefits to coatings. In interior and exterior decorative paints, they act as extenders to improve hiding power and titanium dioxide efficiency. Talc's lamellar platelets make paint easier to apply and improve cracking resistance and sagging. They also enhance matting. In anti-corrosion primers, talc is used to improve corrosion resistance and paint adhesion. Talc also brings benefits to inks, jointing compounds, putties and adhesives.

Talc is used in both uncoated and coated rotogravure papers where it improves printability as well as reducing surface friction, giving substantial improvements in productivity at the paper mill and print house. It also improves mattness and reduce ink scuff in offset papers. Used as pitch control agents, talc "cleans" the papermaking process by adsorbing any sticky resinous particles in the pulp onto their platy surfaces, thereby preventing the agglomeration and deposition of these on the felts and calenders. As opposed to chemical pitch-control products that pollute the process water, talc is removed together with the pulp, enabling the papermaker to operate more easily in closed-circuit. In specialty papers such as colored papers or labels, talc helps to improve quality and productivity.

personal care
As it is soft to the touch and inert, talc has been valued for centuries as a body powder. Today it also plays an important role in many cosmetic products, providing the silkiness in blushes, powder compacts and eye shadows, the transparency of foundations and the sheen of beauty creams. In pharmaceuticals, talc is an ideal excipient, used as a glidant, lubricant and diluent. Soap manufacturers also use talc to enhance skin care performance.
