Description
Calcium Carbonate (CaCO3) is a chemical compound that occurs in the form of minerals in extensive sedimentary rocks like limestone, chalk, marble, travertine, tufa, etc. After the extraction of these rocks, it has to go through mining or quarrying processes to obtain a finely ground powder. Calcium carbonate powder either has opaque or clear bright white color. This powder usually appears as odorless and colorless crystals.
The chemical structure of calcium carbonate is thermodynamically stable under normal conditions. This carbonic salt of calcium is used therapeutically as an antacid during gastric problems, phosphate buffer in hemodialysis, and also to treat low blood calcium levels in the body. It is also used in pharmaceutical industries as it is beneficial for treating health conditions like osteoporosis, hypoparathyroidism, osteomalacia, and latent tenancy.
Due to the opaque appearance of pure Calcium Carbonate Powder, it is also used in color cosmetics. Many skincare products use it as the main ingredient since it is specially formulated to control the oiliness of skin due to its dry and powdery texture. Calcium carbonate powder to render a matt finish to the end products makes it an important component of makeup products like face powder, lipstick, foundation, face masks, etc.
