Characteristics and Application :

The chemical compound silicon dioxide, also known as silica (from the Latin silex), is an oxide of silicon and has been known for its hardness since antiquity. Silica is most commonly found in nature as sand or quartz, as well as in the cell walls of diatoms. It is a principal component of most types of glass and substances such as concrete. Silica is the most abundant mineral in the earth's crust.

Commonly used in cosmetic face powders, silica imparts a smooth texture to the skin and allows the powder to blend evenly over the face as well as enhancing the aesthetic and functional quality of the product.
