Synthetic magnesium silicate/Formula
What is silicate magnesium?
Magnesium silicate is a compound of magnesium oxide and silicon. It is the magnesium salt of silicic acid containing an unspecified amount of water. The molecular formula can be expressed more clearly as MgSiO3.
Where is magnesium silicate found?
Magnesium silicate is the primary component of talc, a common ingredient in cosmetics and personal care products. According to the International Nomenclature of Cosmetic Ingredients, talc is ‘powdered native, hydrous magnesium silicate, sometimes containing a small portion of aluminum silicate.
What is magnesium silicate common name?
talc
Magnesium silicate (MgSiO3) when hydrated is most commonly known as “talc”. In the pharmaceutical industry it is used as an anticaking agent to improve powder flow in tablet compression. Talc is used cosmetically in talcum and baby powder as an adsorbent.
How do you make magnesium silicate?
Magnesium silicate (synthetic) is manufactured by the precipitation reaction between sodium silicate and a soluble magnesium salt. The aqueous suspension of the precipitate is filtered and the collected solid washed, dried, classified for particle size and packaged.
How do you activate magnesium silicate?
The process of making highly active decolorizing magnesium silicate comprising mixing an aqueous solution of sodium silicate with sodium chloride, heating the mixture until a precipitate begins to form, adding magnesium chloride, and then heating the mixture until magnesium silicate is formed.
What is made from magnesium silicate?
Talc is a hydrated magnesium silicate that is commonly used in the manufacture of leather, rubber, paper, textiles, and ceramic tiles as well as iron and nickel products.
Is magnesium silicate edible?
Various national and international regulations allow use of this material as an anti-caking agent in a wide variety of powdered foods. When used as a food additive, it is safe to ingest synthetic magnesium silicate.
What is baby powder used for?
These powders are often used to prevent or treat diaper rash around infants’ bottoms and genital areas. Women also commonly use these powders on their genitals to reduce feminine odors. Adult men and women may also use baby powder on other parts of their body to soothe rashes or ease friction on the skin.
Where can talc be found?
Most of the talc deposits in the United States are in metamorphic rocks on the eastern side of the Appalachian Mountains and in rocks metamorphosed in convergent terranes of Washington, Idaho, Montana, California, Nevada, and New Mexico. Deposits of talc are also found in Texas.
Is magnesium silicate water soluble?
Synthetic magnesium silicates are insoluble in water or alcohol. The particles are usually porous, and the BET surface area can range from less than 100 m2/g to several hundred m2/g.
