Magnesium silicate is widely used across various industries. In the pharmaceutical field it is used as an excipient in tablets and powders. In the food industry it functions as an anti-caking agent in powdered products. It is also used in cosmetics to enhance texture and absorb oil and in industrial processes such as filtration purification and as a filler in paints and plastics.

The primary purpose of magnesium silicate is to act as an absorbent anti-caking agent and stabilizer. It helps improve the texture flow and shelf life of products by preventing clumping and absorbing excess moisture or oils.

Magnesium silicate has a fine powdery texture and is chemically stable insoluble in water and capable of absorbing oils and moisture. It may exist in different forms including hydrated and anhydrous varieties depending on its preparation and use.
