What is the more common name of hydrated magnesium silicate?
Synthetic magnesium silicate Synthetic magnesium silicate Synthetic magnesium silicates are white, odorless, finely divided powders formed by the precipitation reaction of water-soluble sodium silicate (water glass) and a water-soluble magnesium salt such as magnesium chloride, magnesium nitrate or magnesium sulfate. The composition of the precipitate depends on the ratio of the components in the reaction medium, the addition of the correcting substances, and the way in which they are precipitated. The molecular formula is typically written as MgO:XSiO, where X denotes the average mole ratio of SiO to MgO. The product is hydrated and the formula is sometimes written MgO:XSiO•HO to show the
Synthetic magnesium silicate other monographs for Food Grade synthetic magnesium silicate specify a mole ratio of 2MgO:5SiO. The most common use for Food Grade synthetic magnesium silicate is as an active filter aid for adsorption of color, free fatty acids and other polar compounds from used frying oils. 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. In 1990, the safety of synthetic magnesium silicate was reviewed by the Scientific Committee on Food (SCF) together with that
