Overview of Magnesium Silicate

Magnesium Silicate is a mineral-based compound made from magnesium, silicon, and oxygen. It belongs to the group of magnesium silicate minerals and is usually supplied as a fine powder. The chemical formula of magnesium silicate is MgSiO₃, and its CAS number is 1343-88-0.

Magnesium Silicate is well-known for its capacity to absorb water and oil, remaining solid and stable, and not reactivity readily with other substances. These characteristics make it suitable for a wide range of controlled and industrial applications.


Application of Magnesium Silicate

1. Pharmaceutical Applications

In the pharmaceutical industry, magnesium silicate powder is used as an excipient and adsorbent. It helps powders mix evenly and flow better during tablet and capsule production. It also helps control extra moisture and oils.

It is often used together with Talc and Colloidal Silicon Dioxide to improve product consistency.

2. Cosmetic & Personal Care Applications

Magnesium Silicate is commonly used in face powders, foundations, creams, and lotions. It helps absorb excess oil and gives products a smooth and soft feel.

In many cosmetic products, it is mixed with Kaolin Clay and Zinc Oxide to improve oil control and skin comfort.

3. Food & Industrial Applications

In food processing, Magnesium Silicate is used to stop powders from clumping. It helps keep spices, seasoning mixes, salt, and other dry food products free-flowing.

In industrial use, Magnesium Silicate works as a filter aid and processing material. It is used in paints, coatings, and chemical manufacturing to help control moisture and improve product quality.
