Magnesium aluminum silicate is a complex silicate refined from naturally occurring minerals. It is used in a variety of cosmetics and skincare products to improve the texture and function of the formulation.

Magnesium aluminum silicate is a naturally occurring mineral derived from silicate ores of smectite clay. It is refined to a powdery, white solid for use in cosmetics and pharmaceutical applications. Due to the large size of its molecules, magnesium aluminum silicate is unable to be absorbed into the skin, making it ideal for make up products. Magnesium aluminum silicate is often used in products that have a high pH level.

Safety: The safety of magnesium aluminum silicate has been assessed by the Cosmetic Ingredient Review Expert Panel, a group responsible for evaluating the safety of skincare and cosmetic ingredients. Because of its solid particle form, some studies have shown that this ingredient could be irritating if contact is made with the eyes.
