Talc
Coloring:
Talc is a silicate-containing magnesium mineral known by the chemical formula Mg3Si4O10 (OH) 2. This mineral always has impurities with it, which of course is a pure mineral in nature, but it is very rare. Impurities associated with talc are usually manganese oxide, quartz, carbon, and iron, and due to their acidic properties, although poorly soluble in acid. Talc is fatty, slippery, and soft due to its high density and weak molecular bond, and if the density of talc increases, it is used as soapstone. Talc can be used in a variety of industrial coatings, especially primers, and this material gives a wide range of benefits to paint coatings. The plastic shape of the talc particles improves the suspension of solids in the can and helps the liquid paint to stick to the wall without falling.
Grounded talc particles come in many forms, but sheet particles are more common. Particle diameters vary from 5 to 10 micrometers, but there are micronized types that have opaque and antifouling properties. Talc is used in protective paints when high strength is required.
Cosmetic:
Talc is a natural mineral material. It is the softest known mineral from which the smallest powders are made and is used in almost everything from dyes to fabrics and medicines and of course cosmetics.
In fact, in all kinds of cosmetic productions, rich pigments are used that cannot be used directly on the skin. For this reason, it is necessary to use a kind of diluent to dilute these pigments, and talcum powder is used as a dilator, which is used to produce a variety of cream powders, lipsticks, and all kinds of shadows Used. Also, hair conditioners and body conditioners contain some talcum powder.
Medicinal:
Talc is used in the pharmaceutical industry as an oil and lubricant. In pharmacy, talc is used as a filler to facilitate the flow of tablet granules in funnels, to separate compressed pieces from each other, and to easily separate the granules from inside the boxes, and as a lubricant in the coating of tablets. Talc used in this industry must be pure, free of bacteria, must not contain iron oxide, dolomite, carbon, and other impurities.
This talc is asbestos-free and has an extraordinary purity and rarity.
