Cosmetic Grade Talc Powder Udaipur, Rajasthan

Talc is a naturally occurring mineral whose chemical name is hydrated magnesium silicate (h2mg3(sio3)4). It is formed by metamorphosis of sedimentary rocks namely dolomite, pyroxenite, amphibolite and serpentine.

Pyrophylliteis a naturally occurring mineral. Its chemical name is hydrated aluminium silicate alsi2o5oh or al2o3.4sio2.h2o. Thus, it contains 28.3% al2o3, 66.7% sio2 and 5% h2o.

Calcite, as the name suggests is a naturally occurring mineral calcium carbonate (caco3). Its composition is identical to that of limestone but the latter occurs as sedimentary beds.calcite is present extensively in rajasthan, india, where anand talc is located. It is found in veins traversing various rock types particularly within the aravalli and ajabgarh series, which are ancient mountain ranges of rajasthan. Calcite veins 30 to 150 cm thick, running uniformly sometimes for long distances, are usually found. Calcite of very high brightness of upto 99% is found in rajasthan.

Dolomite structure is formed by an ionic interaction of mg2+ (magnesium cation), ca2+ (calcium cation), and co32- (carbonate anion). For every two carbonate anions there is one magnesium cation and one calcium cation, thereby making the structure electrically neutral.

Feldspar comprises of group of aluminum silicate that contains sodium (naalsi3o8), potassium (kalsi3o8)or calcium(caal2si2o8).feldspars are the most abundant mineral in earth’s crust, making up more than 60% of the crust.

Kyanite is a typically blue silicate mineral, commonly found in aluminium rich metamorphic or sedimentary rocks. Kyanite is a member of the alumino-silicate series, which includes the polymorphs, alusite and sillimanite, which have the same chemical composition (al2o3.sio2) as alusite and sillimanite but it is distinguished from those two minerals by its physical properties.

Sillimanite is an alumino-silicate mineral with the chemical formula al2sio5. It is one of the three allotropic varieties of mineral corresponding to the formula al2o3 sio2. The other two are an adalusite and kyanite. They all contain 63.2% al2o3 and 36.8% sio2. They are distinguished from one another by their modes of occurrence and physical and optical properties.
