What is hydrated silica?

The

hydrated silica dioxide consists of chemical silicon oxide in a form that is bound to water molecules. The water content of hydrated silica oxide may vary, and if silica is completely dissolved in water, the compound is called silicate acid. In nature, hydrated silica occurs in various forms, for example as a diatomaceous country and as opals. Hydrated silica can also be made and then usually contains plenty of water for the production of white gelatin, which lacks taste and odor and which can be used as mild abrasive and to increase viscosity or thickness of different products. This substance is non -toxic and commonly used in products of toothpaste, cosmetics and body care.

silicon, also known as silica and which has a chemical recipe SIO _{2, is metaloid, which means that it has some of the metal characteristics and some of the characteristics of non-metal. It must not be confused with a silicone that is a polymer. Silicon is one of the most common CHemic elements on the ground and in the form of silicon oxide are located in sand, quartz, flint, granite and many other minerals.}

in the form of hydrated silica oxide is also found in cell walls of the algae -called diatomas. DIATOMACEOUS EARTH, type of soft, sedimentary rocks mined for various industrial use, consists of hardened sediments of fossilized diatoms. It is also found as opals, a type of gem that consists of silicon oxide with water containing water, which is usually 6-10%.

very common use for produced hydrated silica is as a toothpaste component, valued for its abrasive properties that help remove plaque and number. In a conventional dental heel, hydrated silica often mills until the grain has a diameter of about 8 microns. For use in special bleaching toothpastes, grains are somewhat larger, commonly 10 microns in diameter, which gives an abrasive effect. In older tsDiatomaceous land was used for the same purpose for the same purpose. This substance is also used in various personal care products, such as creams for skin, deodorants and face peel.

In chemistry, hydrated silica is sometimes referred to as an inert substance, which means it is not chemically reactive. This substance is unknown that it is toxic or causes cancer and food and drug management (FDA) in the United States classified it as generally recognized as safe (gras). It is important not to confuse this type of silica oxide with silica crystalline oxide, a toxic substance.
